【正文】 easefree areas of construction in order to further accelerate the development of swine industry realizes space and conditions. 2, the international markets at present, annual volume of trade in live pigs in the world year around 18 million, about 6 million tons of pork trade. A large exporter of pork is mainly the EU and North America,importing countries mainly in Asia, Japan, and Korea, and Singapore, the Philippines, Hong Kong and other countries and regions, as well as Russia, about 3 million tonnes were imported. It is predicted that the world meat consumption increase of 80% in Asia in the future, our country has obvious geographical advantages, export potential. With the advancement of live pigs superiority industry belt construction, animal disease ...LED research throughout the world was mature enough, why do scientists have LED the light source at all? LED in thermal light has many advantages: small size, low power consumption, long service life, high brightness, low calorie, green, rugged, changing, hightech tip. Industry in the city, the urban landscape lighting brightness do not pursue, but the art of creative design, low power LED product should be able to find his place. LED beam angle is small, directional strong local accent lighting can be made. Problem is to provide designers with a large enough scope, demand should also be beauty in appearance. You can say for sure, LED lighting will lead in the future of fashion and trendy. In agriculture, usually by using artificial light sources are fluorescent lamps with high pressure sodium lamps. In recent years, with photoelectric technology of development, glow diode (LED) of brightness and efficiency also significantly improve, makes this light in facilities agricultural production in the of application into feasible, especially on closed can regulation of facilities agricultural environment (as plant factory, Organization training room, and plant growth box,) is a very right of artificial light. for, main introduced has LED in facilities agricultural in the of application and the development trend [1]. Landscape lighting, do not pursue the brightness, but the art of creative design, LED products should be able to find it es in. Glow angle small of LED direction sex strong, can for local focus lighting。 in package material in the added into scattering agent can achieved 175 degrees of glow angle for larger range within of lighting, problem is currently city night lighting in the units too pursuit high brightness to to Designer provides enough big of select range, currently in city night lighting engineering in the mon of LED light main has: linear glow lamps, and decorative lawn lamp, and landscape lamp, and ball bubble, and water Xia lamp, and ground lamps: to buried lamp, and glow tiles, and stone lamp, and The use of solar energy LED lighting [2]. LED medical applications of research at the international level in the 1990 of the 20th century, the 1993 United States Space Agency (NASA) first LED research on biomedical applications. Its contents include: the use of LED light soothing astronaut fatigue, injury, used for Photodynamic therapy of tumors and reduce skin inflammation, ulcers, promotion of wound healing as well as facial skin rejuvenation, wrinkle, spot removal, treatment of sores, and so on. Launched LED medical applications are Israel and the United Kingdom. Through extensive clinical practice, experts agree that LED the international biomedical munity medical equipment is by far the most alternative of HeNe laser phototherapy devices, has an extremely wide range of development foreground in medical applications [3]. LED circuit design is very important, no drive LED you39。ll never be too light. Each manufacturers by with LED are is as of, different of at is drive circuit of different, good of drive circuit can makes its work time more long, play more of role, save more of energy, LED pared Yu General of incandescent by with power more less, but can issued also of light, using years also more long, are because has various high performance quality of circuit makes LED... application of the Chinese language application for proxy bidding agency application system. bidding agent applications should be submitted by the Agency included in the 5th chapter of the content, and than select file asked to provide appropriate documentation. proxy application shall affix its official seal coding and page by page in the specified location. Agent a copy of the application shall have to number the pages and signed original copy (copy) (including supporting documents), and copy should be exactly the same. application there shall be no loose pages. agent application should be plete with indelible ink (powdered) prints, the agent shall not alter any page of the application. bidding agencies offer should be based on the interim measures for the management of tendering agent39。s service charges (meter prices [2022]1980) rules of the Nih, tender agent service charges using the difference progressive billing rate. Charges in accordance with the tendering agent39。s service charges and, in conjunction with the provisions of the specific circumstances of the project shall not be floating up and downfloating range must not exceed 20%, otherwise the application cannot pass pliance checks, be invalidated. Due to bidding agency selection and principalagent contracts signed during charging base bid amount has not yet been produced, it can only be according to the rates of price, bid and the bid amount determines after the end, controlled response rates calculated shall pay tender fee (tender agency fee accounts for the actual bidding agent item for fares). Than the selected person tendering agent39。s service charge control the upper and lower limits, Cap for the State Development Planning Commission of the interim measures for the management of tendering agent39。s service charges (meter prices [2022]1980) of tendering agent39。s servi
