Similarly, we have investigated the stable structure of Ge20 and found that its ground state structure is different from that of Si20. But the most stable structure is also a stacked structure from the ground state structure of Ge10 (tetracapped octahedron with Td symmetry), which is in agreement with the fragment experiment.

类似地，我们首次对Ge20团簇的稳定结构进行了同样的研究，发现它的基态结构与Si20团簇的不同，但它同样以Ge10团簇的基态结构（四帽八面体，Td对称性）为单元的一个堆积结构，这与碎片实验结果吻合。

Methods Polymerase chain reaction and restriction fragment length polymorphism was used to identify mdm2 genotypes. The Pearson Chi square test and Woolf statistic method were used to analyze the relative risk and 95% confidence interval in order to find the genetic association between polymorphism of mdm2 gene and symptoms and pathological types of NSCLC.

采用聚合酶链反应和限制性内切酶片段长度多态性方法检测88例NSCLC患者的mdm2基因型，并通过Pearson卡方检验及Woolf方法计算相对风险度及95%可信区间（95%CI），验证mdm2基因多态性与各临床症状及病理类型之间的关联性。
