Primary results are shown as followings: 1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation. The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。

通过实证检验发现，我国金字塔结构下民营上市公司的治理效应有以下特征：控制权与公司价值显著负相关，说明实际控制人掌握的控制权越大，公司价值越低；现金流权与公司价值显著负相关，这可能与我国民营上市公司控股股东的"掠夺性分红"行为有关；现金流权与控制权的分离率和公司价值负相关且未通过显著性检验，这可能与控股股东的"掠夺性分红"行为有关，也可能与市场的不完善、信息披露的不充分等有关；股权制衡度与公司价值显著正相关，说明我国民营上市公司的股权制衡机制能够产生一定程度的效果；实际控制人参与管理情况与在控股股东单位任职的董事比例和公司价值的关系均未通过显著性检验；公司规模与公司价值显著负相关；ROE对公司价值没有解释力。

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.
