The results show that:1) the mean salinity of the NYSCWM center has a slightly decreasing trend,which is not consistent with the high salinity center; 2) both the southern salinity front and the halocline of the NYSCWM display a weakening trend,which indicates that the difference between the NYSCWM and coastal water decreases; 3) the Yellow Sea Warm Current intrusion,the E-P flux of the northern Yellow Sea,and the strength of the winter monsoon will affect the NYSCWM salinity during the following summer.展开更多

Yet consensus on the issue has almost never been reached among theorists and practitioners. In this paper, a detailed comparison between academic and professional assessment has been made mainly in terms of text type, assessment criteria and models. It is believed that a ＂one size fits all＂ model across academy and industry is neither possible nor necessary. However, the gaps in between could be narrowed down by increasing communication and cooperation between theorists and practitioners, who are advised to turn their focus to translator＇s competence and evaluation process.展开更多
文摘The establishment of agricultural products quality and safety cooperation mechanism and the research demonstration center in the Asia-Pacific reg coordinating each other, is not only of great ening cooperation with countries in Asia-Pacific region and for agricultural production safety of those countries in Asia- Pacific region, but also very necessary for our country to build a responsible image in the quality and safety of agricultural products, protection of the benefit of agriculture-related enterprises, increasing exports, ensuring imported food safety and China＇s national food security, as Well as nice exploration of establishing the global agricultural＇ products quality and safety cooperation center.
