Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.

结果表明不同肺炎链球菌株的转化最适菌密度不同，1、2和22号菌株的最适转化密度分别为0.1、0.08和0.07；用于转化的CTM培养基最适为pH 8.0的C+Y培养基；在自然转化下不能诱导转化发生的pH 6.8的C+Y培养基中，使用CSP诱导，也能促使细菌发生转化，只是转化效率较低；结论：实验室条件下，不同细菌在一定菌密度时可利用CSP诱导肺炎链球菌成为感受态发生转化。2、为探讨肺炎链球菌转化对毒力表达的影响，本研究分别通过体外粘附人脐静脉血管内皮细胞ECV-304和体内小鼠毒力实验观察1、2和22号肺炎链球菌和其转化缺陷菌株1t、2t和22t毒力的差异。

The existing points and lines would form a closed geometric shape. If we put the new point Z outside the closed geometric shape at first and later then found that the point Z has neighboring relationship with the existing point A which is inside the closed geometric shape, we could not link point Z and A directly because that would bring line crossing. If we rearrange the point Z into the closed geometric shape, that also would cause a lot of work to do. With the help of Exclave, all problems could be solved easily. We use point X outside the closed geometric shape as the Exclave of the point A. Then the line between point Z and X could demonstrate the neighboring relationship of the point Z and A.

原有的各点和相邻线段往往会形成一个封闭的几何图形，如果我们把新增点 Z 设在原有的封闭几何图形外部，后来又发现该点 Z 和位于封闭几何图形内部的点 A 存在相邻关系，这时不能直接将两点连接因为那将产生交叉，而如果将点 Z 重新设在封闭图形内部也将导致大量的调整工作；此时借助外飞地的概念，可以轻松地解决上述问题，即在封闭几何图形外部设置点 X 作为点 A 的外飞地，两点使用同样的颜色，用点 Z 和点 X 的相邻线段表示点 Z 和点 A 之间的相邻关系。
