After the optimal design, some parameters of the impeller such as entrance angle and diameter and have been changed. The improved impellers efficiency and cavitation performance are better than the former one.

通过对叶轮入口处的流场分析，证实了该泵性能下降是由汽蚀造成的推测；基于速度系数法建立了叶轮优化的数学模型，通过得到的流场数据和该数学模型对原叶轮进行了优化设计，优化结果对叶片的入口角和叶片的入口直径等参数进行了改进，优化后的叶轮达到了提高泵的汽蚀性能和效率的目的。

The authors stress that they cannot prove whether antibodies against MOG and MBP have demyelinating capacity or whether they represent an epiphenomenon of myelin destruction.

作者强调，他们不能证明抗MOG和抗MBP抗体是否具有使髓鞘脱失的能力，或它们是否表示髓鞘受到破坏的现象，作者表示，抗MOG和抗MBP抗体的分析对于临床上出现分离症状的患者而言，是迅速、低廉，和精确的早期临床预测法，可以预测多重硬化症的发展，而这项研究结果对于咨询和推测发生第一次髓鞘脱失之患者是否患有多重硬化症，是相当重要的。

Therefore, we hypothesized that apoptosis is a significant mechanism of injury to duct epithelium.

Despite all of this, autobiography remains a useful tool for ethnological research: such personal reminiscences and impressions, incomplete as they may be, are likely to throw more light on the working of the mind and emotions than any amount of speculation from an ethnologist or ethnological theorist from another culture.

除了这些，自传对种族研究来说还是一个有用的工具：这种个人的回忆和印象，尽管可能不完整，比起一个另一种文化的种族学家或者种族理论家的任何大量的推测，更有可能揭示思想和感情的作用。

They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .

因此从处理效率和环境化学意义两方面考虑，结合本课题组在不同铁形态（包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等）的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础，本论文选择了四类共9种典型的内分泌干扰物（雌二醇（E2）、雌酮（E1）、17α-乙炔基雌二醇（EE2）己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯），研究了它们在Fe-草酸盐配合物体系中的光降解效果，推测其降解机理，探索环境内分泌干扰物光氧化处理的新体系，同时为预测其在环境中的光降解行为提供了依据。
