Both the results of ISSR and AFLP showed a low degree genetic polymorphism and gene flow, which indicated that self-pollination might be the main breeding system in T.

ISSR及AFLP遗传多样性分析表明延龄草居群内多样性程度及较低，居群间及居群内均出现了一定的遗传分化。

In the study of semigroup, the regular semigroups research occupies the dominant position.

在半群的研究中，正则半群一直占半群代数理论研究的主导地位。

To investigate the mechanisms of biohydrogen production by anerobic fermentation of solid organic waste, gas chromatography is used to analysis the biogas and volatile fatty acid in anaerobic bio-reactor. Firstly, the ability of hydrogen production by digested sludge from the West Lake, Enteobacter aerogences, digested sludge from sewage farm, the fluid of methane pool and dejecta have been studied. The rule of the ability of hydrogen production by different bacteria under different control condition. Simultaneity, the importance of the synergistic effect on hydrogen production has been proved.

本文首先选用西湖底的厌氧活性污泥、产气肠杆菌、污水处理厂的淤泥、沼气池发酵液以及猪粪等不同菌群对废弃食物——马铃薯进行厌氧发酵产氢特性实验研究，得到马铃薯在各不同菌群及工况下的发酵产氢能力，同时发现产氢菌间的协同作用很重要，在控制好发酵条件的情况下，产氢菌群发酵通常会好于单一产氢菌的发酵。

SSR markers are used to do cluster analysis on 100 snap bean germplasms which divided into 6 groups.

利用SSR标记的多态性对100份菜豆种质资源进行聚类分析，根据聚类分析结果，所有供试材料在相似系数为0.33～1.00范围内聚在一起，在阈值0.54处可将所有的种质资源分成六个组群，第一组群主要是由肉质脆的蔓生菜豆构成，这一组群的遗传背景丰富。

By using the c-supplementation of Sylow 2-subgroup and Sylow 3-subgroup, we obtain two sufficient and necessary conditions for a finite group to be solvable.

利用Sylow 2-子群和Sylow 3-子群的c-可补性得到有限群成为可解的两个充要条件，推广了几个已知的定理。

We first characterize the groups in which all m∈cdq〓 contain at most 4 prime divisors; and then show the following: if any m∈cdq〓 is nth-power-free then the derived length of solvable group G is bounded by a function f depended only on n; also if cdq〓 has k different p-parts then the p-length of solvable group G is bounded by a function g depended only on k.

首先研究了非线性不可约特征标对应的特征标次数的商至多含有4个素因子的有限群结构。其次，我们证明：若每m∈cdq〓是n次方自由的，则有限可解群G的的导长及p-长都被仅依赖于n的函数所界定；若cdq〓中共有k个两两不同的p-部分，则有限可解群G的p-长能被仅依赖于k的函数所界定。

We followed tracks and signs of a large group of lion cubs that moved considerable distances, without the guidance or protection of adults. There were approximately ten cubs, and from the size of their spoor, they were no older than a year. These were unusual observations. Generally, lionesses give birth to small litters of 2 – 3 cubs, although they do occasionally synchronise their oestrus cycles and produce litters about the same time. However lion cubs, of that age, are mostly in the company of adults. Textbooks and the scientific literature suggest that one-year-old lions are dependent on the adult lionesses of their pride, and could not survive on their own.

我们跟踪由一大群幼狮留下足迹的其他记号，这些狮子没有其他成年狮子陪同和保护，粗略估计，这群狮子的数量接近10只，他们足迹的尺寸显示他们不会超过1岁，这是不常见的，通常情况下，母狮会生下至少2～3头幼崽，但也有个别例外的时候，然而在这个年龄段的幼狮大都有"母亲"陪同，许多书上介绍，1岁大的小狮在离开狮群母狮的照顾后是无法生存的。

Comparative study of Chinese sport s shoe indust ry cluster and foreign ones indicated that besides beneficial competitive and cooperative relation , highly advanced labor division , the lat ter embraced st rong innovative ability. The local government and the intermediaries had same service function ,common cultural background and system.

对我国运动鞋业集群与国外运动鞋业集群进行比较研究，发现国外成功的运动鞋业集群除了企业间良好的竞争合作关系与高度发达的劳动分工以外，还有极强的知识创新能力，地方政府与中介服务机构完善的服务功能以及具有共同的文化背景与制度环境。

We can get a lot of information about the structure of the group from the properties of its subgroups.

子群的性质对群的结构有着重要的影响，通过对它们的研究可以获得关于原群结构的大量信息。

When we do research about the structure of a group, the influence of subgroups is very important.

子群对群的结构有着重要的影响，通过对他们性质的研究往往可以获得大量关于原群结构的重要信息。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。
