What person, how to cultivate people is developing the socialist education enterprise in our country must solve fundamental problem. College students is a national valuable human resources, are the hope of nation, the future of our motherland. To make university students grow up to be the cause of socialism with Chinese characteristics qualified builders and reliable successors, we not only need to vigorously improve their scientific and cultural quality, and actively improve their ideological and political quality. College students' ideological and the political education content system of the science building is refers to according to the requirements of college students' ideological and political education goal, to constitute elements of ideological and political education content should be reasonable configuration, make each other, permeate each other, in order to realize the content of organic integration and collaborative development.展开更多

Until now, there is limited information available regarding the study of water quality criteria in China. It is imperative to launch national-level systematic WQC studies that focus on the regional characteristics of China and provide scientific support for the enactment or revision of water quality standards and environmental management. This article reviews the concept of WQC and discusses the methodology and global progress of WQC research. The article also summarizes the key scientific issues in WQC research, including species sensitivity distribution, toxicological endpoint selection, and models selection. Furthermore, we can adopt the derivation method used in the USA and divide WQC into acute and chronic criteria. Finally, considering the current status of WQC research in China, we point out important directions for future national studies, including the selection of native species and the comprehensive use of models.展开更多
