in order to establish a rapid, sensitive and specific detection method for identification of four kinds of food-borne pathogenic bacteria including salmonellla spp, listeria monocytogenes, staphylococcus aureus and bacillus cereus by using multiplex pcr, according to invasion protein a geneof salmonellla spp, transcriptional regulatory protein gene of listeria monocytogenes, autolysin gene ofstaphylococcus aureus and gyrase b subunit gene of bacillus cereus, four pairs of specific primers were designed for multiplex pcr amplification.

小 摘要：为建立一种利用多重pcr技术检测和鉴定沙门氏菌、单核细胞增生李斯特菌、金黄色葡萄球菌和蜡样芽孢杆菌的方法，根据沙门氏菌侵袭力蛋白a基因、单核细胞增生李斯特菌蛋白转录调控基因、金黄色葡萄球菌自溶素基因、蜡样芽孢杆菌的促旋酶b亚单位基因设计引物，进行多重pcr扩增，并对多重pcr反应体系进行优化。

Then we define the stable distribution with four equivalent ways and analyze its properties carefully. To study the stable distribution, we must know how to simulate its random variables. We can learn it intuitively by watching its plot of density function.By adding an auxiliary variable in the Chapter 4, we estimate the four parameters using Gibbs sampler.

接着给出了稳定分布的四种等价定义方法，详细的分析了稳定分布的性质，提出如何利用简单随机数产生稳定分布的随机变量以便我们进行分析研究，借助稳定分布近似密度函数的图形我们对它的特征会有更加直观的认识。

This paper is using S Company, which is developing and manufacturing a cell phone key bottom, as the research base. This research is also using hyper links and surveying auxiliary patterns as variable factors to create four kinds of web site frameworks. Furthermore we are taking different background staff, a development team, a non-development team (Sales, Quality and Production department) and new employees to run an experiment to analyze and estimate the efficiency of four kinds of design based web site frameworks.

Objective:to study the level of total anaerobic population, total aerobic population, four kinds of anaerobes and two kinds of aerobes in excrement of sufferers of varies kinds of irritable bowel syndrome and that of normal persons.methods:excrement specimens from 52 ibs sufferers of different kinds and that of 18 normal volunteers were collected, and the level of four kinds of anaerobes and two kinds of aerobes were quantified.results:the level of total anaerobic population and total aerobic population of excrement specimens of three kinds of ibs sufferers were different significantly, particularly the level of bifidobacterium and cillobacterium(p.01);the level of bacteroid population was higher significantly in diarrhea-predominant and mixed type of ibs sufferers (p.01);the level of enterococcus population was higher significantly in diarrhea-predominant ibs sufferers(p.05);among the aerobes, the number of escherichia coli and staphylococcus aureus colonies were increased by different level(p.01or0.05) in the ibs suffers, in particular, the number of escherichia coli colonies in diarrhea-predominant ibs sufferers increased most significantly.conclusion:sufferers of different types of ibs have different intestinal tract dysbacteria phenotypes.
