　　Online celebrity Gewei in Hechi and the 3rd Gepo Festival in Simeng Township, donglan were held in Simeng Sports Park recently, which was the third online celebrity Gewei held since the opening of online celebrity Chuangchuang Camp in Hechi, attracting more than 10,000 people from all counties (districts) in the city.

　　In recent years, the Information Office of Hechi Municipal Committee has taken the initiative to give full play to its functional advantages, with the help of the internet, taking strengthening the construction of network celebrities as the focus and innovation point to promote the construction of network civilization. By building the "online celebrity Creation Camp", the online celebrity House was established, and the "online celebrity Song Fair" was held to unite and unite the online forces such as online celebrity and Media V, tell the story of Hechi well, spread the sound of Hechi well, shape the image of Hechi well, and gather positive energy for the development of Hechi.

　　Be a good "online celebrity" housekeeper and carry forward the new trend of social civilization

　　"This time in online celebrity, there should be a competition for the hegemony of the Zhuang King of Songs", "Our’ Twilight Plan’ public welfare activities can take photos of local longevity elderly people for free" and "Longevity elderly people can’t hold activities to replenish food and prolong their lives" … The curtain of the cultural tourism brand activities of "March 3 Hechi Carnival in Guangxi" has not yet been opened, and the Hechi online celebrity Creation Camp has already become lively.

　　The Network Information Office of Hechi Municipal Committee insists on the Party’s management of the Internet, and incorporates the construction of network celebrities into the main points of the work of the Network Information Committee of the Municipal Committee. As a concrete measure to promote the network civilization work in the whole city, it continues to strengthen the role of network celebrities, and strengthen the contact and friendship of network celebrities through special investigations, seminars and exchanges, and build concentric circles online and offline. We have organized and carried out a series of online theme publicity activities, such as "Hechi online celebrity Hechi Beauty", "Yunshuo Magnificent and Charming Hechi" and "Shaking the New Hechi", focusing on the development of cultural tourism, rural revitalization, online public welfare and other fields, and created thousands of new media works to promote the new trend of online civilization. Up to now, Hechi online celebrity database has collected more than 150 online celebrities with more than 50,000 fans, including more than 10 online celebrities with more than 1 million fans.

　　Be a good housekeeper and bridge the gap for the development of positive energy. Since 2023, more than 30 people, including Xiaojiang Media and Hechi Tribe, have been recommended to participate in e-commerce gatherings, cultural tourism promotion and other activities to help Hechi cultural tourism promotion, agricultural product sales and charity, so that online celebrity and the activists can achieve a double harvest of "flow" and "realization".

　　Be a good "online celebrity" guide and encourage social responsibility.

　　Hechi City has played a leading role in the organization of the Party Committee of the Internet industry, and strengthened the ideological and political guidance for famous online celebrities and enterprises. The Information Office of the Municipal Party Committee and other departments have successively conducted lectures in Internet companies such as Lida E-commerce Logistics Co., Ltd. and Yizhou Forum, constantly rallying ideological consensus and enhancing the political identity, ideological identity, theoretical identity and emotional identity of online celebrities to the Party.

　　The "Hechi City Network Civilization Proposal" was issued to the whole city to guide the local media and network celebrities to consciously fulfill their social responsibility obligations. Hechi tribe, Zhuang township Xiao Mo and other media and network celebrities created and launched more than 1,000 high-quality works such as "Is this the taste of Hechi # Guangxi # Returning to Hechi for the New Year #", and Xiaojiang Media’s online public service advertisement "Even though there are 2020 difficulties, there are still 2021 kinds of persistence (dedicated to you who persist during the epidemic)". Internet celebrities such as Tan Lianqiao and Xiao Fan have devoted themselves to online public welfare undertakings. Online public welfare projects such as the "Neem Flower 1+1 Education Project" in Du ‘an and the "Partner Program" in Dahua Wild Lily have benefited children in mountainous areas, and online public welfare has continuously infiltrated people’s hearts.

　　Hechi City encourages social responsibility by guiding network celebrities to give full play to their own characteristics and advantages, which has laid a solid foundation for promoting Hechi, promoting Hechi and revitalizing Hechi with the help of the Internet.

　　Do a good job of "online celebrity" stylist and set an advanced typical benchmark.

It has set up a column of online celebrity Creation Camp on Hechi.com, organized reporters to conduct an exclusive report on positive energy online celebrity, launched more than 10 daily series of positive energy reports by online celebrity, such as "Mini Brother in Luocheng", and planned to launch a series of video works "New Life in Singing", a folk song with unique Hechi characteristics, to tell the daily stories of online celebrity in Hechi, spread the good voice of the Internet, and guide the cyberspace to form a positive atmosphere.

　　Hechi City pays attention to the demonstration and guidance of network celebrities. By taking activities such as "Five Hundred" and "Strive to be a good netizen in Bagui" as the starting point, and taking the New Media Federation and online celebrity Creation Camp as the positions, it has done a good job in selecting typical trees for netizens. In recent years, it has recommended more than 20 network celebrities such as Gao Dongfeng and Hu Liufang as "good netizens in Bagui" models, moral models, the most beautiful people and good people around them. In addition, in recent years, phenomenal online celebrity, such as Waina, Wu Enshi and rural Xiaojing, have emerged in Hechi, becoming the flag pole of Hechi "online celebrity".

　　In this year’s "V Viewing the New Countryside and Seeing the Changes in Hometown-Hechi New Media Entering Donglan Simeng Public Welfare", online celebrities, light and shadow sculptors and other public welfare organizations took photos of the birthday girl and more than 10 pairs of long-lived elderly people, leaving a precious mark on the old people’s half-century caring for each other. With the flashing of flashing lights, moving and sweet smiles were captured one by one, making the atmosphere of the whole event happy and romantic.

　　Nowadays, the celebrity of positive energy network in Hechi City is gradually becoming an "important online force" for Hechi to further promote the construction of network civilization, becoming a disseminator of positive energy, a recorder of the times, a watcher of fairness and justice, and a promoter of social progress.

What is a digital video camera?

　　Digital Video camera is DV, which is the abbreviation of Digital Video. Translated into Chinese, it means "Digital Video". It is a digital video format jointly developed by many famous home appliance giants such as Sony, Panasonic, Shengli, Sharp, Toshiba and Canon. However, in the joint development of a digital video format. However, in most cases, DV stands for digital camera. According to the purpose of use, it can be divided into: broadcast-grade models, professional-grade models and consumer-grade models. According to the storage medium, it can be divided into: magnetic tape type, optical disk type, hard disk type and memory card type.

Development course of digital camera

　　It has been 16 years since the first digital camera was born in 2011. During these 16 years, digital cameras have undergone tremendous changes. The storage media range from DV to DVD to hard disk, with a total pixel of 800,000 to 5 million, and the image quality ranges from standard-definition DV(720×576) to high-definition HDV(1920×1080).

The first DV camera was born in 1995.

　　In July, 1995, Sony released the first DV camera DCR-VX1000. Once released, DCR-VX1000 was widely adopted by TV journalists and producers all over the world. This product uses Mini-DV format tape, adopts 3CCD sensor (3 1/3 inch, 410,000 pixel CCD), 10x optical zoom and optical anti-shake system, and the price at the time of release is as high as 4,000 yuan. DCR-VX1000 is a major change in the history of imaging. Since then, civil digital cameras have entered the digital age.

The first DVD camera was born in 2000.

　　In August 2000, Hitachi introduced the first DVD camera DZ-MV100. At that time, this product could only be recorded by DVD-RAM. Hitachi first brought DVD as a storage medium into a digital camera, and used an 8cm DVD-RAM burning disc as a storage medium, which got rid of the inconvenience of DV tape and was a major innovation after DV camera. However, at that time, not many people paid attention to this product. DZ-MV100 was only sold in Japan, and it was hard to find a trace in the domestic market. It was recognized that DVD cameras should be widely promoted by Sony three years later.

In 2004, the first micro hard disk camera was born.

　　In September, 2004, JVC launched the first batch of 1-inch micro hard disk cameras MC200 and MC100, and the hard disk began to enter the field of consumer digital cameras. The capacity of the two hard disks is 4GB, and the video images taken are compressed by MPEG-2, so users can flexibly change the compression rate to extend the shooting time. The adoption of hard disk media makes it extremely convenient for digital cameras to exchange information with computers. Both MC200 and MC100 and several subsequent 1-inch micro hard disk cameras can flexibly replace micro hard disks. By June, 2005, JVC released the Everio G series with 1.8-inch high-capacity hard disk camera. The maximum capacity reached 30GB, and the volume was well controlled, and the price remained at the level of similar DV cameras.

In 2004, the first HDV 1080i HD camera was born.

　　In September 2003, Sony, Canon, Sharp and JVC jointly formulated the HD camera standard HDV. In September 2004, Sony released the first HDV 1080i high-definition camera HDR-FX1E. The recording resolution of HDV reached 1440×1080, and the horizontal scanning line was doubled compared with that of DVD, and the definition was revolutionized. HDR-FX1E, including the HDV cameras introduced later, used the original ones.

In 2010, the first 3D camera was born.

　　Up to now, the 3D revolution has all revolved around Hollywood blockbusters and major sports events. With the advent of Panasonic HDC-SDT750 3D camera, this technology is one step closer to home users. Panasonic HDC-SDT750 is the world’s first 3D camera. After the launch of this camera, we can capture every unforgettable moment of life with 3D lens in the future, such as children’s first step, university graduation celebration and so on. Panasonic released the HDC-SDT750 3D camera on July 28th, 2010. The official price is RMB 11,998 (excluding 3D lens). It is designed with dual lenses and equipped with Panasonic’s high-end series of 3mos image sensors. (What is a 3D camera? )

Working principle of digital camera

　　The basic principle of digital camera is simply the transformation and transmission of optical-electrical-digital signals. That is to say, the light signal is converted into current through the photosensitive element, and then the analog electric signal is converted into digital signal, and the information obtained after processing and filtering by a special chip is restored to be the dynamic picture we see.

　　The photosensitive element of digital video camera can convert light into charge, which is converted into digital signal through analog-to-digital converter chip. There are two main types: one is widely used CCD (Charge Coupled Device); The other is CMOS (complementary metal oxide conductor) device.

　　Characteristics of digital camera

　　High-definition analog cameras record analog signals, so the image definition (also called resolution, resolution or resolution) is not high. For example, the horizontal definition of VHS cameras is mainly 240 lines, and it is best to mention that Hi8 models only have 400 lines. DV records digital signals, and its horizontal resolution has reached 500~540 lines, which can be comparable to professional cameras.

　　The bandwidth of chroma and brightness signal of DV is almost six times that of analog camera, and the bandwidth of chroma and brightness is one of the most important factors that determine the image quality, so the color of the image shot by DV is more pure and gorgeous, and it has reached the level of professional camera.

　　The signal recorded on the lossless reproduction DV tape can be transcribed countless times, and the image quality will not be degraded at all, which is beyond the reach of analog cameras.

　　Small size and light weight Compared with analog cameras, the size of DV cameras is greatly reduced, generally only about 123mm×87mm×66mm, and the weight is greatly reduced, generally only about 500 grams, which greatly facilitates the users’ size is only 74.7mm×61.9mm×26.9mm and the weight is only 90 grams, which is even lighter than most mobile phones.

Digital camera classification

　　I. Classification according to the purpose of use

　　1. Broadcast-grade models:

　　These models are mainly used in the field of radio and television, with high image quality and comprehensive performance, but with higher price and larger volume, they have the highest definition, the largest signal-to-noise ratio and the best image quality. Of course, the price of several hundred thousand yuan is not acceptable to ordinary people. For example, Panasonic AJ-HPX3100MC and other models.

　　2, professional models:

　　These models are generally used in professional TV fields other than radio and television, such as audio-visual education, and the image quality is lower than that of broadcast cameras. However, in recent years, some high-end professional cameras have surpassed the old models of broadcast cameras in many aspects, such as performance indicators, and the price is generally between tens of thousands and hundreds of thousands of yuan.

　　Compared with consumer models, professional DV is not only cooler and more eye-catching, but also much higher in configuration, such as the use of lenses with better quality performance and the larger size of CCD, which is more prominent in imaging quality and adaptability to the environment. For friends who pursue image quality, the surprise brought by the improvement of image quality can’t be measured by money at all. Such as Sony’s HXR-NX5, the price is around 34,000.

　　3. Consumer-grade models:

　　This type of camera is mainly suitable for home use, and it is used in non-business occasions with low image quality requirements, such as home entertainment, etc. This type of camera is small in size, light in weight, easy to carry, simple in operation and cheap in price. It can be used to make VCD and DVD of personal family in occasions with low requirements, and the price is generally in the order of several thousand yuan to ten thousand yuan. Such as Sony’s HDR-XR160E.

　　If we subdivide the home digital cameras, they can be roughly divided into the following categories: entry-level DV, mid-range consumer-grade DV and high-end quasi-professional DV products.

　　Second, according to the classification of storage media

　　1, tape type:

　　Refers to the digital video camera with Mini DV as the recording medium, which was first developed by more than 10 manufacturers in 1994. Record high-quality digital video signals through a 1/4 inch metal vapor deposition tape.

　　2, CD-ROM:

　　Refers to the DVD digital camera, the storage medium is DVD-R, DVR+R, or DVD-RW, DVD+RW to store dynamic video images, which is simple to operate and easy to carry, and there is no need to worry about overlapping shooting during shooting, let alone wasting time to rewind or play back, especially it can be played immediately through the DVD player, which saves the trouble of post-editing.

　　DVD media has the highest security and stability among all media digital cameras at present. It is neither as easy to wear and tear as tape DV, nor as demanding as hard disk DV for shock prevention. The disadvantage is that the price of DVD is slightly higher than that of tape DV, and the time for recording is relatively short.

　　3, hard disk:

　　Refers to a digital video camera that uses a hard disk as a storage medium. It was first introduced by JVC in 2005, using micro hard disk as storage medium.

　　Hard disk cameras have many advantages, and large-capacity hard disk cameras can ensure long-term shooting, so that you will not have any worries when traveling. When you get home, you can transfer the shooting materials to the computer, and you no longer need the complicated and professional video acquisition equipment as in the era of MiniDV tape camera. You can easily export the materials just by connecting with the computer through USB cable, so that ordinary family users can easily experience the fun of shooting and editing video films.

　　Like CF card, micro hard disk is smaller than DVD, and its service time is the most impressive among many storage media. However, due to the short time of hard disk DV, there are still many shortcomings, such as poor shock resistance and so on. With the further decline of prices, the number of people in need will inevitably increase in the future.

　　4. Memory card type:

　　Refers to the digital video camera using memory card as storage medium, such as the popular "X Easy Shooting" product. As a transitional simple product, it is rare in the market now.

　　Three, according to the type and number of sensors.

　　1. Sensor types: CMOS and CCD.

　　CCD: Charge Coupled Device image sensor, which is made of a high-sensitivity semiconductor material, can convert light into charge, which is converted into digital signal by an analog-to-digital converter chip.

　　CMOS: Complementary metal-oxide semiconductor, like CCD, is a semiconductor that can record light changes in digital cameras.

　　At the same resolution, CMOS is cheaper than CCD, but the image quality produced by CMOS devices is lower than CCD. So far, most consumer-grade and high-end digital cameras on the market use CCD as sensors; CMOS sensors are used in some cameras as low-end products, but some high-end products also use special CMOS as light sensors, such as several high-end CMOS models of Sony.

　　2. Number of sensors: single CCD and 3CCD.

　　The number of image sensors is the number of CCD or CMOS sensors of digital cameras. Most digital cameras use a single CCD as their sensors, while some middle and high-end digital cameras use 3CD as their sensors.

　　Single CCD means that there is only one CCD in the camera and it is used for photoelectric conversion of brightness signal and color signal. Because a CCD completes the conversion of brightness signal and chroma signal at the same time, the captured image can not meet high requirements in color reproduction.

　　3CCD, as its name implies, is a camera using three ccds. We know that if light passes through a special prism, it will be divided into three colors: red, green and blue, and these three colors are the three primary colors used in our TV. Through these three primary colors, all TV signals including brightness signals can be generated. If a CCD is used to receive each color and convert it into an electrical signal, and then an image signal is generated after circuit processing, a 3CCD system can be formed, which can display the primary colors of the image almost intact, and there will be no color error caused by camera deduction.

　　It’s the season to enjoy pineapple at will, and its sweet fragrance is everywhere in fruit shops and mobile fruit carts on the street, which is irresistible! However, many people have had this experience: pineapple will "sting"! Not only will its coat and crown on its head prick hands, but its flesh will also sting its mouth! Our oral cavity will be strongly stimulated, resulting in tingling, acidity and itching of oral mucosa and gums. What’s more, it suffers from bleeding, inflammation, redness and swelling around the mouth and lips. This is why people often soak pineapples in salt water first — — Reduce the intensity of its "sting mouth".

　　Why do pineapples sting?

　　Because pineapple is so "smart", in order to prevent humans and other creatures from eating it, it not only wears a barbed armor, but also hides three heavyweight weapons in the flesh.

　　The first heavy weapon: calcium oxalate needle crystal

　　Calcium oxalate needle crystal is the physical killing means of pineapple. Under the microscope, the bundle of calcium oxalate needle crystal wrapped by pulp tissue cells is like countless dense needles. They have a very powerful characteristic: they are insoluble in water. So it is not easy to be dissolved by our saliva!

　　When we chew pineapple pulp, we will destroy the tissue cells of the pulp because of the grinding of teeth, which is equivalent to opening the door to these invisible sharp needles that originally locked them. Once these sharp needles are released into the mouth, they will mercilessly "plunge" into any mucosal tissue they touch. With our continuous chewing, calcium oxalate needle crystals can be "pushed" into our tongue, inner wall of mouth, throat and gums, which are soft, delicate and have no resistance.

　　The second weapon: bromelain

　　This enzyme can be extracted from the pulp, peel and even stem of pineapple. Little friends who often cook must be familiar with this enzyme, because it is an important "second party" of tender meat powder. The common tender meat powder is either papain or bromelain.

　　Proteases, as the name implies, can decompose protein. On the one hand, bromelain will activate the "PAR" protease "alarm" in oral epithelial cells and free nerve endings, and after being activated, it will awaken the nerve pathway that can trigger itching. On the other hand, bromelain itself does destroy the protein of our oral mucosa — — It is achieved by decomposing and "cutting" the connective proteins between cells.

　　In this way, the defense network of oral mucosal cells is "relaxed" and the barrier protection is weakened, which makes it easier for some pathogens to take an opportunity to trigger inflammation or immune response.

　　Knowledge small link:

　　In fact, many fruits and vegetables contain both calcium oxalate crystals and proteases, such as papaya, spinach and figs. When we eat these fruits and vegetables, we won’t have obvious irritation, because the calcium oxalate crystals they contain are not needle-shaped, but oval or dumbbell-shaped and other non-lethal irregular shapes, so they won’t hurt our oral mucosa.

　　But kiwifruit is an exception. Calcium oxalate crystals in kiwifruit pulp are also needle-shaped, and kiwifruit also contains cysteine proteolytic enzyme. Therefore, when we eat kiwifruit, we will feel tingling more or less. Therefore, kiwifruit is also a kind of fruit that can "eat people", but it is not as fierce as pineapple, probably because its weapons and equipment are not as good as pineapple.

　　The third weapon: organic acids

　　The sour taste produced by organic acids such as citric acid, malic acid and quinic acid contained in pineapple not only stimulates our taste receptors, but also stimulates the pain receptors in the oral cavity. Combined with the first two weapons of pineapple, the lethality is self-evident.

　　The "killer" to conquer pineapple

　　How many have you learned?

　　In order to conquer the killer of pineapple and make it a delicious dish for human beings, our ancestors summed up several stunts for us:

　　1. Salt water soaking: This is the most common treatment method, which is said to "destroy bromelain". However, this principle is controversial and unsolvable, because sodium chloride in table salt is not a heavy metal salt, so it can’t denature protein. At best, some organic acids in pulp can be dissolved in water by soaking in salt water, thus reducing the stimulating effect of organic acids. Moreover, it is a bit salty to be sweet — — A small amount of salty taste can increase the taste buds’ perception of sweetness, which makes us feel "Wow! So sweet and beautiful! "

　　Of course, some people support that salt can reduce the activity of bromelain, and tell us through laboratory research data that different concentrations of salt water can really improve the problem of pineapple sting to varying degrees. When the concentration of saline increased significantly (from 0% to 3.5%, and then to 7% and 10.5%), the activity of bromelain decreased gradually. But what is the principle, it seems that it has not been verified.

　　2. Pepper salting: This is a classic way to eat in Guangdong, Guangxi and Hainan. It is sweet, sour, salty and spicy, and it is very delicious. As for whether the pain caused by spicy taste overwhelmed the acupuncture pain of pineapple in the end, or whether capsaicin and salt together inhibited the activity of bromelain, it is hard to say. I really expect someone to study this topic well to solve my confusion.

　　3. Heating: As a protein afraid of heat, bromelain can’t continue to show off at high temperature. When pineapple pulp is heated above 60 degrees Celsius, bromelain will be inactivated and calcium oxalate needle crystals will be dissolved to some extent. This is also the reason why pineapple pulp in delicious foods such as pineapple goo old meat and pineapple rice won’t make us feel stung. However, after heating to this temperature, the crisp, tough and cool taste of the pulp may be discounted, and interested friends can try it.

　　However, there must be some friends who refuse to heat the pineapple and are too lazy to soak it in salt water. So, how can you enjoy the delicious pineapple and relieve the pain of your mouth? The following two items are for reference — —

　　1. Make a quick decision: don’t eat slowly for a long time, and don’t give pineapple black weapons a chance to kill you fully;

　　2. Rinse your mouth in time: rinse your mouth immediately after eating pineapple to reduce the residence time of calcium oxalate needle crystals and bromelain in your mouth. If you like, you can rinse it several times, and the effect will be better. Text/Liu Suiqian (popular science worker, clinical nutritionist, member of China Nutrition Society)

　　With the advantages of long snow period, good snow quality and diverse terrain, Xinjiang has built a number of high-standard ski resorts, forming two major ice and snow tourist belts, Tianshan Mountain and Altai Mountain, which are popular areas for ice and snow sports in China.

　　The Altay Mountain Ice and Snow Tourism Belt, which is dominated by Altay region, is located in the northernmost part of Xinjiang. Altay is known as the "origin of human skiing", and the snow season can reach 7 months throughout the year, which is very suitable for carrying out ice and snow sports.

　　Starting from the snow season in 2021, Peng Chao, a senior snow friend from Beijing, rented a wooden house in Hemu Village, deep in Altai Mountain, Xinjiang, as the team’s work site in the next few years. The team mainly carries out skiing equipment evaluation and popular science skiing knowledge, and is well-known among domestic skiers. Peng Chao said that Altay region is located in the world’s ice and snow resources ‘ Golden latitude ’ All the natural advantages of other international ski resorts are available here. During his stay in Hemu, he and other members of the team promoted the knowledge of avalanche risk avoidance and advocated the concept of safe and sustainable mountaineering and skiing.

For the platform operator, as long as the customers in the store scan the code to link WiFi successfully, you will get a profit, and this part of the profit is calculated automatically. Your profit is settled by Tencent’s traffic, and the following will form the effect of automatic operation. When others connect WiFi, you will get a profit, and the system operator will just enjoy the profit.
