Soil microbial biomass and activities of invertase and urease all tended to decrease after pot-culture experiment, while the correlations between these biochemical properties and field ages were similar to those before this experiment, suggesting that rice cultivation without fertilization consumed part of soil microbial biomass, decreased soil enzyme activities correlated with C and N transformation, and affected soil nutrients status disadvantageously.

温室盆栽试验之后，水稻土的微生物生物量及酶活性与利用年限之间的关系规律和种植水稻之前基本一致，且整体上又趋于下降，即无施肥条件下种植水稻转化利用了土壤部分微生物生物量，并减弱了与碳氮转化相关酶的活性，对保持水稻土的营养水平造成不利影响。

Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.

Silicon phthalocyanine dihydroxide was prepared from silicon phthalocyanine dichloride through two methods. The first was alkali treating that meaned silicon phthalocyanine dihydroxide was treated in the ethanol solution containing sodium methylate .The second was acid treating meaned precipitating its solution in concentrated sulfuric acid into ice water. The product yield of the second method was 77.0％, which was higher than the method of alkali treating.
