Chishui River, a first-order south tributary of upper Yangtze River, extends cross Sichuan, Yunnan and Guizhou provinces and is famous as the “eco-river with a lot of endemic fishes”, “Beauty River with natural scenic landscapes”, “Chinese famous liquors river with Maotai” and “hero river”. According to the existing problems in Ecological Environment of the Chishui River, the ecological compensation mechanism was established and the compensation of the main watershed ecology, ecological compensation object, ecological compensation standards and ecological compensation ways were determined, for protecting the environment requirements of the rare and unique fish and Liquor industry production of Yangtze River.
This article aims to conduct a systematic review of studies on teaching of Spanish as a foreign Language (ele) for the specific purpose of foreign trade in Vocational and Applied Education in China between 2000 and 2019. A search in the two most well-known and used bibliographic bases in China (China National Knowledge Infrastructure -cnkiand wanfang data) allows to identify the thematic areas on study so far: ele curricular development; the role of foreign languages in the training of professionals in foreign trade; and activities and strategies for teaching. There is still a very recent interest (especially since 2009) in this field of study. The results draw an overview of the emergence of different challenges, including the study of communication and learning needs of ele for different professional performances.
This paper elaborates the control of environmental factors in the modern industry and agriculture, and according to the problem that the temperature and the humidity is hard to control automatically, this paper puts forward the design of the greenhouse automatic control system based on MSP430 single chip microcomputer. This design mainly introduces the overall design scheme of the automatic control system, and the use of the properties of various hardware based on MPS430, which mainly include temperature transmission sensor DS18B20 and the humidity transmission sensor CHR01. And then use the environmental control factor algorithm and numerical conversion fuzzy algorithm, so as to realize the temperature and humidity control system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
