The so-called Pharmaceutical Intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a pharmaceutical production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for the synthesis of pharmaceuticals.
Our country needs more than 2,000 kinds of raw materials and intermediates for chemical industry every year, and the demand is over 2.5 million tons. After more than 30 years of development, the chemical raw materials and intermediates required for the country's pharmaceutical production can basically be matched, and only a small part of it needs to be imported. Moreover, due to my country's abundant resources and low raw material prices, many intermediates have been exported in large quantities.
On the one hand, product updates in this field are fast. Generally, after a product has been on the market for 3 to 5 years, its profit margin will drop significantly. This forces companies to continuously develop new products or continuously improve production processes in order to maintain a high production profit; on the other hand, due to the production profit of pharmaceutical intermediates Higher than chemical products, the production process of the two is basically the same, so more and more small chemical companies have joined the ranks of producing pharmaceutical intermediates.

In terms of resolution, the definition of HD network high-speed ball has achieved a qualitative leap, providing users with more picture pixels and showing more abundant picture details. Liang Ge, Product Manager of Tianjin Yaan Technology Electronics Co., Ltd., said that compared with the analog and standard speed domes, the resolution of the megapixel high-speed ball is generally more than 720p, which avoids the original monitoring picture is not very clear, even In some places, there is a phenomenon where the fuzzy resolution is not clear.
Under the premise of ensuring the improvement of resolution, the HD network high-speed dome can expand the monitoring range of coverage, which means that the coverage of a high-definition camera is equivalent to several times that of an analog high-speed ball, which can provide users with more details of events or reduce the speed The number of balls used. For example, in a safe city or a place requiring extensive coverage, the previous ordinary ball machine may require 200 units, while the use of high-speed network high-speed ball only needs 100 units, 18 times the speed of 720p network high-speed ball coverage is equivalent to 36 times The D1 effect was mentioned by Zou Yufan, training consultant for ANZ China Network Communications Technology Co., Ltd. in China.
In addition, it is worth noting that the high-definition network high-speed ball can also provide users with timely and effective monitoring services through the addition of intelligent analysis functions. It is more convenient for positioning and tracking in outdoor complex environments. In the high-definition network high-speed ball more typical intelligent analysis technology includes motion detection, face recognition and so on. For example, based on behavior analysis technology, intelligent analysis functions such as personnel focus, traffic detection, over-the-line detection, and alarm real-time upload functions can be implemented. 'Hu Ping, product manager of Hikvision mentioned. At the same time, on the basis of high-definition image quality, it can be combined with face analysis functions to match the application of facial data in the database. If some of the key locations are found to be robbery incidents, they can be traced more quickly and accurately. Or, it analyzes the flow of customers and goods in shopping malls and supermarkets, and provides managers with analysis of the flow of people and businesses. Chen Yong, product manager of product monitoring and control of product solutions at Panasonic Corporation (China) Co., Ltd., mentioned.
In addition, some manufacturers such as Panasonic to ensure that the peripheral pixels of the high-speed ball image can also reach the level of high-definition, built-in image correction software, can quickly rotate or sphere generated image correction.
The development trend of high-speed network surveillance high-speed ball is not at all drastic
As we all know, the reason why high-definition network high-speed ball gradually shines on the market, precisely because the market put forward the demand for high-definition surveillance. Moreover, compared to the traditional analog high-speed ball, the HD network high-speed ball has a high-definition picture, a wider coverage, easy-to-expand performance, and intelligent analysis functions, and can meet the high demands of users in the market.
