With two methods, plate cultivation and the novel semi-solid in situ cultivation method, strains belong to Family Leptothrix were isolated. XRF showed that the amorphous iron and manganese were two major metal elements of the precipitation formed by one strain of Leptothrix spp..

研究发现，铁细菌2号培养基为合适的分离培养基；采用平板涂布法分离出的2株氧化铁和锰的细菌，经系统发育地位的分析确定为纤发菌属；对运动纤发菌的产物分析确定无定形铁和锰为其主要金属元素；形态观察确定霍氏纤发菌呈树枝状鞘结构，而运动纤发菌呈蛛网状鞘结构。

The results indicate that the best model for DNA evolution of rbcL sequences in Liliales is GTR+I+G, and the topology of Bayesian tree is similar to those of Maximum parsimonious tree and Neighbor Joining tree, but giving more resolution and higher support values.

结果显示，百合目rbcL基因最适合的DNA进化模型为GTR+I+G，贝叶斯法与距离法和最大简约法构建的系统发育树拓扑结构相似，没有显著差异，但是分辨率和支持率明显比后者高。

Chieftain with the degenerate primers by RT-PCR.The cDNA clone of 3GT encodes a predicted polypeptides of 448 amino acids,and the deduce protein showed 76% highest identity with 3GT of Petunia hybrida and Solanum melongena,and the multiple alignment and phylogenetic analysis demonstrated that it belong to a new member of the corresponding 3GT-family enzymes.

序列分析表明，这个3GT基因编码的多肽为448个氨基酸残基，在氨基酸水平上与茄科的矮牵牛和茄子的一致性最高，均为76%，多重比较和系统发育分析均表明，该基因为3GT家族中的一个新成员。

In my study, based on morphological and biological studies, 53 character transformation series of 23 species which stand for 23 genera of the Microgastrinae in China respectively and 2 species of Miracinae and Cardichilinae were selected. Through analysis of character polarity using the method of outgroup analysis, two and multiple character data matrixe were obtained. The data is analysed through PHYLIP(Phylogeny Inference Package, version 3.6) software based on the method of cladistics, the consensus cladograms was constructed at last.

本研究以分布在中国东洋区和古北区的小腹茧蜂亚科23个属的23个种作为内群，奇脉茧蜂亚科和折脉茧蜂亚科各一种作为外群，基于形态学和生物学分析建立了53个性状演系列，通过外群比较法，得到一个由二性状和多性状数据矩阵，再用phylip(系统发育推断软件3.6版)处理数据矩阵，最后得到合意树。

In order to elucidate the phylogenetic relationships of genus Bryodemella and answer such question as whether Bryodemella is a monophyletic genus, all 8 species of this genus were dealt with and a cladistic analysis is performed using thirty-four characters from external morphology in this paper.

为阐明异痂蝗属Bryodemella种间系统发育关系并回答该属是否为单系的问题，本文在研究外部形态结构的基础上选择了34个不同性状对异痂蝗属所有8种进行了支序分析，结果只产生1棵步长为55、一致性指数和保留指数均为0.80的最简约树。
