| 3 | NON-EQUILIBRIUM SEGREGATION OF SOLUTE TO GRAIN BOUNDARIES显示文摘In consideration of the local equilibrium among vacancies,solute atoms and vacancy-soluteatom complexes and the influence of equilibrium grain boundary segregation,theoretical dy-namic formulas for non-equilibrium grain boundary segregation of solute have been derivedon the basis of the vacancy-dragging mechanism.Theoretical calculation by computer hasbeen carried out for the non-equilibrium segregation of boron to austenitic grain boundariesduring isothermal holding and continuous cooling after heating at high temperatures.The re-suits agree well with those obtained from experiments. | CHU Youyi ZHANG Sanhong HE Xinlai KE Jun(T.Ko) University of Science and Technology Beijing,China CHU Youyi Professor,The Nonferrous Metals Society of China,Room 602,B12,Fuxing Road,Beijing 100814,China | 1990 | Acta Metallurgica Sinica(English Letters)1990，3，1： | 0 |
| 4 | FULL TIME-SPACE GOVERNANCE STRATEGY AND TECHNOLOGY FOR CROPLAND NON-POINT POLLUTION CONTROL IN CHINA显示文摘Ensuring food safety while reducing agricultural non-point source pollution is quite challenging,especially in developing and underdeveloped countries.Effective systematic strategies and comprehensive technologies need to be developed for agricultural non-point source pollution control at the watershed scale to improve surface water quality.In this review,a proposal is made for a full time-space governance strategy that prioritizes source management followed by endpoint water pollution control.The 4R chain technology system is specifically reviewed,including source reduction,process retention,nutrient reuse and water restoration.The 4R chain technology system with the full time-space governance strategy was applied at the scale of an administrative village and proved to be a feasible solution for reducing agricultural non-point source pollution in China.In the future,a monitoring system needs to be established to trace N and P transport.Additionally,new smart fertilizer and intelligent equipment need to be developed,and relevant governance standards and supportive policies need to be set to enhance the efficacy of agricultural non-point source pollution control. | Lihong XUE Jingjing DUAN Pengfu HOU Shiying HE Yingliang YU Yanfang FENG Fuxing LIU Linzhang YANG | 2023 | Frontiers of Agricultural Science and Engineering2023，10，4： | 0 |
