A series PCR amplification for differential control strains and DNA samples diluted gradient (1:10) have been used to evaluate the specificity and sensitivity of PCR assay established.Results 1. Detection of GAS by PCR assay: The 345bp specific fragment of speB gene were amplified in all the tested GAS strains including three strains of scarlet fever, whereas it was detected in none of the differential control strains. The lowest limit of detection was 6.5pg genome DNA of GAS strain. 2. Detection of corynebacterium diphtheria by PCR assay: The318bp specific fragment of toxB gene were amplified in all the tested toxigenic corynebacterium diphtheria strains, whereas it was detected in none of the differential control strains. The lowest limit of detection is 850fg/μl genome DNA of corynebacterium diphtheria strain. 3. Detection of Lp by PCR assay: The 340bp specific fragments of mip gene were amplified in all the tested Lp strains, whereas it was detected in none of the differential control strains including three strains of non-pneumophila.

结果：1、用PCR方法检测A组链球菌：以A组链球菌致热性外毒素基因speB为靶序列，设计的扩增引物对全部对照菌株的扩增结果为阴性，而全部A组链球菌参考株均能扩增出特异的345bp片段，其中包括三株猩红热链球菌，检测敏感性为6.5pg／μl DNA.2、用PCR方法检测白喉杆菌：以白喉外毒素基因toxB为靶序列，设计的扩增引物对全部白喉杆菌参考株均能扩增出特异的318bp片段，而全部对照株的扩增结果为阴性，检测敏感性为850fg／μl DNA.3、用PCR方法检测嗜肺军团菌：以嗜肺军团菌巨噬细胞感染增强子基因mip为靶基因，设计的引物对嗜肺军团菌14个血清型参考株均扩增出特异的340bp片段，而鉴别对照株包括三株非嗜肺军团菌均未扩增出任何片段。

Because trimethyl silyl-substitited PPO have similar gas solubility but various diffusivity, difference between gas permeability is mainly caused by gas diffusion coefficient.

故二者气体透过系数的不同主要是由于扩散系数的差异。

According to the development characteristics of regional caprocks,great efforts have been made to analyse the effect of it on oil and gas accumulation and preservation in different aspects. We consider regional caprocks to be the good barriers to prevent oil and gas in free phase from escaping. If uncompacted and possessing abnormal pore fluid pressure,regional caprocks are the barriers to prevent oil and gas in water dissolving phase from escaping.

根据区域性盖层的发育特征，从不同侧面对其在油气聚集与保存中所起的作用进行了深入分析，认为区域性盖层通常是阻止游离相油气逸散的良好区域物性屏障；如果其欠压实，具异常孔隙流体压力，它还可以成为阻止水溶相油气逸散的区域压力屏障；如果其再具生烃能力，还可以成为阻止扩散相天然气逸散的区域浓度屏障。

According to these mentioned above, it can be concluded that there are 4 types of accumulation model in west slope region, that is, sandstone up-dip trap, structure and structure—lithology trap, fault—lithology trap, sandstone lenticular body trap, and that oil-gas accumulation and distribution are mainly controlled by some factors that is trap growth, relationship of between trap and space orientation of oil-gas migration pathway, connection area of centripetal flow and centrifugal flow, oil-gas preservation condition and unconformability.
