Results (1) From more than 100 primers, 11 primers producing polymorphism and reproduceable bands were selected, 129 bands were amplified.(2) The percentage of polymorphic bands within different populations were 20.9%-55.0%.(3) The cluster map including all samples were obtained by UPGMA. In the map, there were six cluster groups and three individuals outside the groups. The branch with five samples of Zhongjiang Sichuan population were far from other samples in genetic distance.(4) According to the distribution provinces five groups were divided in genetic variance analysis. Genetic variance 80.44% existing within population, 8.29% among populations and 11.27% among groups.

结果 （1）从100多个引物中选择出11个多态性强和重复性好的引物，扩增得到129条带；（2）不同居群内多态位点比率为20.9%－55.0%；（3）用UPGMA法得到所有样本的聚类图，可分为6个主要分支组和3个组外个体，其中四川中江居群的5个样本聚为一组，并与其他样本遗传距离较大；（4）按产地分组，遗传差异的80.44%存在于居群内，8.29%来自于组内居群间，11.27%的遗传差异来自于组间。

They were divided into two groups:elderly group(with 3 or more centrums hyperosteogeny) and younger group(with less than 3 centrums hyperosteogeny). Then they were evaluated according to Meyerding method and analyzed by χ2 and Fisher accurate probability examination.Results Among the younger group,any degree of lumbar spondylo-listhesis had all prominent relationship with spondylolysis.

方法回顾2002年以来笔者所在医院放射科腰椎滑脱患者316例，对腰椎滑脱采用Meyerding法分级，把腰椎滑脱的患者分为老龄组(腰椎同时有3个以上椎体骨质增生)及青年组(腰椎未见骨质增生或有1～2个椎体骨质增生)，同时，在不同年龄组中对不同程度腰椎滑脱患者分组并利用SPSS13.0进行χ2和Fisher精确概率检验分析，得出结论。

When compensating devices are switched by vacuum switches, if they are switched on group, the inrush current can be controlled by inserting suitable current-restrained reactance in-series. Since the restriking overvoltage is pertinent to the capacity of compensating devices and the time of restriking and igniting, the overvoltage can be restrained by arresters with asterism connection at the entrance of the capacitors. Although switching capacitance devices will bring up high interception cross overvoltage, the metal-oxide arrester can limit this overvoltage in the system designed in the thesis, and naturally the compensating devices can operate normally.
