The thesis analyzed chiefly on on law of physical sign disposition of deficiency of spleen-QI in pedo-eczema.Using pykno-analysis, data has been analyzed. We got 23 physical signs of statistical significance,and had non-conditional logistic regression analysis to them. We got 11 physical signs of great value in pedo-eczema diagnosis,including dim-coloured anthema, athrepsy body, weak pulse, diarrhea , etiolate complexion,light texture of tongue,soft skin, house-wife hand,dim qichi, fissured tongue, bluish tendon in shangen etal.And contrast with former diagnostic criteria of deficiency of spleen-QI published by TCM administration bureau, unearch part of the unnoticed physical signs.

论文着重分析了小儿湿疹脾气虚证的体征分布规律，采用频数分析方法，对数据进行统计学分析，分析出其中具有统计学意义的23项体征，并对其进行非条件性logistic回归分析，得出对小儿湿疹诊断具有重要价值的疹色暗淡，形体消瘦，脉无力，便溏，面色萎黄，舌质淡，尺肤松软，手掌纹理增多，气池暗，裂纹舌，山根青筋等11项体征，并与以往国家局的脾气虚证证候诊断标准对照，从而发掘出部分以往未被重视的体征。

The first synthetic route uses 1,2,4-trimethoxybenzene and chloroacetonitrile in forming 2,4,5-trimethoxy-a-chlor-acetophenone under the anhydrous condition, then the intermediate condensates with papaverine forming the core pyrro[2,l-a]isoquinoline, followed by formation and lactonization to form the lactone ring. The second synthetic route uses prepared aldehyde with prepared ethyl nitroacetate by Knoevenagel condensation to obtain 2-Nitro-3-(2,4,5-tris-methoxy-phenyl)-acrylic acid ethyl ester and 2-Nitro-3-(2,4,5-tris-benzyloxy -phenyl)-acrylic acid ethyl ester etal intermediates. The lamellarin skeleton could arise from condensation of the papaverine and these intermediates by Michael reaction, the ester group is provided for subsequent lactonization. The third synthetic route uses coumarin or indan-l,3-dione derivatives and papaverine to form lamellarin under basic conditions.

Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.
