Based on literature cite and expert＇ s interviewing etc. this text makes analysis to the present resource-using condition of the coliseum in the economy-oriented society, and puts forward related countermeasures of the coliseum＇ s development as reference to decision makers.展开更多

The results indicate that subsided water areas are polluted in different degree. Some physicochemical indexes of subsided water areas are increased with the development of the subsidence and are changed with the changing of the season. The concentration of As, Cd, Cu, Pb, Se, Zn of subsided water areas is less than national fishery, and surface water quality standards of China , except Hg. And the quality of subsided water hasn＇t been polluted by heavy metal seriously. Analyzing and appraising the quality of the subsided water can give a reasonable data as basis in using the subsided water resource.展开更多

文摘Constructing a conservation-oriented society is a very urgent mission for China at present, and how the large-scale athletic events carry through economical principle and policy is the topic that each physical worker needs research. Based on literature cite and expert＇ s interviewing etc. this text makes analysis to the present resource-using condition of the coliseum in the economy-oriented society, and puts forward related countermeasures of the coliseum＇ s development as reference to decision makers.
文摘The subsided water areas with different times of subsidence are chosen to monitor the physicochemical indexes and heavy metal elements. The results indicate that subsided water areas are polluted in different degree. Some physicochemical indexes of subsided water areas are increased with the development of the subsidence and are changed with the changing of the season. The concentration of As, Cd, Cu, Pb, Se, Zn of subsided water areas is less than national fishery, and surface water quality standards of China , except Hg. And the quality of subsided water hasn＇t been polluted by heavy metal seriously. Analyzing and appraising the quality of the subsided water can give a reasonable data as basis in using the subsided water resource.
