Phthalic acid esters are widely used in the many fields of industry. So many countries including China have come to pay attention to them and make up the codes for limiting the content in some products such as textile. By combining international codes, the thesis selects coating and textile that have close relative with people as objections. The research results are as follows:1. The thesis has established the textiles preparation method by a series of experimentations such as extraction solvent, extraction time, solid-phase extraction. The average recoveries of eleven phthalates are from 80.30% to 98.00%, and the relative standard deviations from 0.59% to 2.56%, the results show that this method is accurate and credible.2. The thesis set up the simultaneous determination of benzene, toluene, xylenes and phthalates in coatings.

邻苯二甲酸酯类化合物被广泛地应用在工业领域的各个方面，国际上已经开始重视邻苯二甲酸酯作为一种内分泌干扰素的危害性，对在一些产品中的用量作出了限制，但没有具体的分析测定方法，本论文结合国际法规选择了与人们生活密切相关的涂料和纺织品来研究其中邻苯二甲酸酯类环境激素的测定方法，研究内容如下：(1)通过对提取溶剂、提取方式、提取时间的选择实验以及固相萃取的一系列条件实验，首次建立了纺织品中测定邻苯二甲酸酯类环境激素的前处理方法，并对分析方法作了准确度、精密度验证。

RT-PCR was a sensitive and stable method. It would be useful for large-scale diagnosis.A length cDNA of CEVd had been cloned into plasmid vector. Biotinylated probes were prepared from these plasmid DNAs. CEVd were examined from the positive and netative materials by Dot-blotting hybridization and imprint-hybridization. The result was exposed to x-ray film. Singles were detected for positive materials spots probed with probe, indicating that under the reaction conditions the probe hybridized with the target viroid specifically.

核酸杂交法检测：利用已经克隆的美国柑桔裂皮类病毒cDNA序列，制备生物素标记的核苷酸探针，采用斑点杂交的方法和组织印迹的方法分别对阳性材料进行杂交检测，通过胶片曝光显示杂交信号，发现在两种方法的检测结果中阳性材料都有强的反应，而阴性材料无反应或较弱，该方法安全可靠、快速准确，适合大量样品的检测。

The problem with temps is that they are temporary and local.

临时变量的问题在于他们的生命周期都是临时的而且作用域是局部的，因为只在那些应用这些变量的方法的上下文中，他们才是可见的，所以临时变量更应该被封装成一个长一点方法，这是你延伸这些临时变量应用范围的唯一途径，通过用一个类似查询的方法来替换临时变量，类中的任何方法都可以访问临时变量所携带的信息，这对获得更清晰的代码有很大的帮助。

Learning-theory has an apparent improving effect on students" learning the basic skill of table-tennis. In the comparison between tested group and compared group, an obvious difference appears; it also has a positive effect on students" learning interest, for it can make students keep more interest in learning; using learning-theory is able to improve students learning method of table-tennis. Based on the similar initial learning level of tested group and compared group, and through a one-term teaching experiment, apparent difference of learning method between tested group and compared group arrears, and the learning method of tested group is better than that of compared group.

学习理论对学生学习乒乓球的基本技术有明显的促进作用，在实验组与对照组的比较中表现出显著性差异；对学生的乒乓球学习兴趣也存在积极的影响，可以使学生保持较高的学习兴趣；学习理论应用到乒乓球教学中还可以提高和改善学生的乒乓球学习方法，在实验组与对照组学习方法基线水平无显著性差异的基础上，通过一学期的教学实验发现，实验组与对照组在学习方法上出现显著性差异，实验组的学习方法好于对照组。

Firstly, This text has described information fusion technology characteristic, form structure and concrete processing method, and application of information fusion in fault diagnosis proves the feasibility and validity from the angle of information theory. Based on this,it is combined the fault diagnosis of aeroengine with Information fusion, a method and model which the fault diagnosis of aeroengine information fusion is brought forward. a research which combined neural networks with D-S evidence is brought forward. Based on the analysis of single neural network characteristic, the model of roted neural network is put forward. With the simulation based on the example, we can know evidence theory fusion improved the fault diagnosis It is hard to give the basic probability function in the process of using the evidence theory, So the model based on network and D-S evidence is put forword.
