Agricultural non-point pollution is formed by 4 processes of rainfall runoff, soil erosion, surface solutionstripping and soil solution seepage.
农业非点源污染主要由降雨径流、土壤侵蚀、地表溶质溶出和土壤溶质渗漏4个过程形成。

Suitable conditions of stripping palladium with ammonium chloride-(ammonia) solution are also studied.
也考察了氯化铵的氨水溶液反萃取钯的适宜条件。
