Research result indicated that the cooperative effect between swell and precursor is main factor for the nanoparticle loaded in Nafion, and moreover, polarity of solvent and water content in Nafion also affects the load largely. To improve away the surface concentration of CdS nanocrystal on two side of membrane for general preparation, thioacetamide was first used as a precursor instead of inorganic sulfur source(H2S and Na2S) in synthesis of CdS nanocrystal. The assembly mechanism for several sulfur source had been studied, and CdS/Nafion with the character of homogeneous disperse had been prepared, which is fit for mass transmission in photocatalitic reaction. Following the investigation of several crystallizing way, simple and reliable hydrothermal-crystallizing was found. According to this way, maximal TiO2 load in Nafion achieved 43%. Activity of TiO2/Nafion or CdS/Nafion as a photocatalyst was explored initially for disintegrating liquid contamination. Maximal decompose rate achieved 86% under condition of this research.

研究结果表明：Nafion膜对纳米粒子负载量的主要影响因素是溶胀作用与前驱体协同效应，同时溶剂极性和薄膜含水量对负载量也影响相当大；本课题首次使用硫代乙酰胺代替传统无机硫源（H2S、Na2S）合成CdS纳晶，研究了各种硫源的组装机理，克服了常规技术存在的CdS纳晶趋于膜表面富集的缺点，得到了有利于光催化传质需要的体相均匀分布CdS/Nafion；研究了多种Nafion膜内纳米粒子晶化途径，找到了简单可靠的水热晶化法，TiO2纳晶最高负载量达43％；初步探索了TiO2/Nafion、CdS/Nafion作为光催化剂降解水中模拟污染物的活性，在本实验条件下最高降解率达86％。

The article discusses the purpose and significance of the subject. it is dictated definitely that if we depend on the exhausting gas from engine to diagnose the fault of automobile by applying the neural network model.the result reduces the contamination of the exhausting gas of the used vehicle on our environment, abridges repair time, decreases the repair master's labor intensity and improves labor efficiency.Meanwhile,it is in favor of the management of the I/M system.

本文对该课题研究的目的和意义进行了探讨，明确提出如果能根据汽车尾气参数值，应用神经网络模型判断发动机的故障，这将大大减少了汽车尾气对大气环境的污染，缩短维修时间，降低工人师傅的劳动强度，提高劳动效率，同时也有利于I/M制度的管理。
