Slope stability FEM analysis and retaining wall design：a case study of clinker in Benxi of Liaoning

Stability is always the most important problem after high slope was excavated. The study analyzed the stress and strain inside the slope by Finite Element Method （FEM） and carried through stress distribution and failure zone, then analyzed the stability of the slope using three different methods and came to the conclusion that it is in unstable condition, so the designed retaining wall was put forward which makes the slope stable.     

石英砂选矿厂尾砂综合利用研究

为了实现石英资源的综合利用和保护环境，对原来的石英砂生产工艺进行了改造，降低了石英尾砂中的杂质含量，基于石英砂中SiO2含量高，粒度细的特点，开发出了以石英尾矿为原料生产石英粉的新工艺，所得产品符合无碱玻纤和釉料熔块工业的要求。     

硼酸铝制备熔块中硫酸钾浸溶动力学

用明矾与硼和硫酸钾在１１５０℃下合成硼酸铝晶体,得到圆柱型绕结块。对于在水中,不同搅拌速率（１００－８００ｒ／ｍｉｎ）、温度（２０－８０℃）和酸度（盐酸０．１－２．０ｍｏｌ／Ｌ,硫酸０．１－１．０ｍｏｌ／Ｌ）时熔块中硫钾的浸溶动力学进行了研究,用Ｓｔｕｍｍ和Ａｖｒａｍｉ方程计算,给出了动力学方程及活化能。
