Then, Through the analysis to the groundwater pollutant component in mine area, it utilizes the theory of fuzzy math to appraise the groundwater quality in mine area, which relatively conforms with facts, and realizes electronic process of fuzzy appraisal with Matlab procedure. 然后通过对矿区地下水污染物组分的分析,利用模糊综合评判法,对矿区地下水水质做出了比较合乎实际的评价,并实现了模糊评价的电算化。
The third part is mainly about the research of questioning in math class of middle school. Analyze some problems in class questioning and point the facts that affect the optimization of class questioning. 第三章是初中数学课堂提问的相关研究,通过课堂观察分析当前课堂提问存在的问题,并指出影响课堂提问优化的因素。
