The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.
对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析,结果支持原目、愈腹目的单系性,长角目不形成单系群,支持短角科从愈腹目中分出,但鳞总科和短角目的分类地位有待于深入分析探讨;进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列,以1种多足动物和1种螯肢动物为外群,进行系统关系分析,结果显示:原尾纲、弹尾纲、双尾纲分别为单系群,原尾纲和双尾纲优先聚为一支,然后和弹尾纲构成姐妹群,以上三类又和昆虫聚为一支,支持六足动物的单系性,支持泛甲壳动物,但甲壳动物并未形成单系,其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

After verification of FEM, 45 species of 15 series are computed. The major parameters including slippage coefficients, pretensions forces, dimensions of angles, arrangement of bolts, connection method among angle, beam web, column flange, and so on are studied. Some important conclusions are drawn.At last, Advices for seismic design based on tests and FEM analysis are presented at last. The study is rather comprehensive and systematic, and the conclusions. can be useful for revising design code, guiding design of engineering, and provide good basis for further to study behavior of shear beam-to-column connections.
