A method for determinating the activities of pectinase was proposed in this paper. It can produce the red-brown amino compounds when 3,5-dinitrosalicylic acid and aldehyde were heated together. The amino compounds had maximum absorbency at 540nm. In certain range, there was a good linear relationship between the amount of reducing sugar and the color of the reaction mixture.

针对QB1502-92标准测定方法测定高活力果胶酶、固定化果胶酶活力存在的实验误差大，重现性及灵敏度差的缺陷，提出了利用3，5-二硝基水杨酸与醛糖共热产生棕红色的氨基化合物，在一定范围内还原糖的量和含有呈色氨基化合物的反应液颜色深浅成正比的原理，在540nm下测其吸光度，从而计算出果胶酶活力的测定方法，并对测定步骤、影响因素及测定中可能出现的问题进行了试验研究。

There was no color, music, weather, andpeople didn't have real feelings.

由于这些缺陷，公民们没有了生活中的享受，而且，其结果是，他们不会象我们一样珍惜生命。

Crystallites in the form of a round hollow column were present in the matrix of the ablated surface.

提出了运用运输问题方法求解小规模基本物流网络设计的方法，同时弥补了已有研究中无法解决的网点建设费用问题以及忽视了物流费用规模经济问题的缺陷； 6。

Based on the theory of fuzzy mathematics,the improved fuzzy optimum model was established,and an integrated selection method,which combined quantitative index with qualitative index of the enterprises of engineering project authorized management,was developed.

通过运用模糊数学的相关优选理论，建立了改进的模糊优选模型，给出了一种在代建制下对代建单位进行定性、定量综合评选的方法，在定性指标的量化处理上用模糊一致矩阵克服了传统方法的缺陷。

AHP and entropy method were combined together as synthetical evaluation index, which overcame the problem of dependability produced by single method in practice.

在评价指标权重方面，采用层次分析法和熵值法相结合的方法计算各评价指标权重，克服了单一方法在实际应用中得到的可信度存在一定偏差的缺陷，提高了评价结果的精度和可信度。

The matrix organizational structure combined the advantages of the former two, and overcame their disadvantage.

但是，矩阵式组织结构也存在权限模糊、命令不统一等缺陷，这是我们在设计EPM的组织结构时应该避免问题。

In chapter 4, employing the molecular dynamics simulations, we study the melt-ing transitions in driven vortex lattices with commensurability between arrays ofvortices and defects.

在第四章中，采用分子动力学模拟，研究了在涡旋与钉扎缺陷之间匹配条件下的驱动涡旋晶格的融熔转变。

It is shown that the mechanical properties including Young's modulus, tensile strength, critical strain and stress under buckling can be enhanced with the decreasing of intershell spacing. The shear strength can be enhanced by 2-3 orders of magnitude when the intershell spacing is reduced to 20%, which is also dependent on commensuration. Zigzag-type carbon nanotubes have higher shear strength. The axial stress in tubes when the load transferring from outmost tube to inner tube is observed as well.

研究了单壁纳米管束横截面的六方化失稳现象，给出各种管径的面内压力－应变关系曲线；每条曲线都给出一个明显的拐点而且有很强的非线性；线弹性模量与参考构形有关，也受管直径的影响；分析了管束横截面的晶格不稳定性特征，表明晶格的缺陷能够明显的减小临界值；模拟了在不同应变下纳米管束对静水压的反应，发现不同压力下的截面形态不同，在很高压力下相邻管之间会形成化学键。
