Lam. and its related species are called plants of Ipomoea section batatas, which are classified into two groups based on the cross-compatibility with sweetpotato: Group I cross-compatible with sweetpotato and Group II cross-incompatible with sweetpotato.

根据同甘薯的杂交亲和性，将甘薯组植物分为两个群：同甘薯杂交亲和的第Ⅰ群和同甘薯杂交不亲和的第Ⅱ群。

In this paper we obtain Jorgensen s inequality of isometry group M of Pinched manifold X and a geometric characteristic of nonelementary subgroups of M.

本文建立了 Pinched流形 X上等距群 M中的Jorgensen型不等式；证得了M中非初等群的一个几何特征；得到了 M中子群的两个离散准则。

If a loop is isotopic to a group, then it is isomorphic to that group and thus is itself a group.

如果一个圈与某个群同痕，那么它与此群同构，因此也为一个群。

And a way to find the elements ofthat are conjugate to is proposed. Then we prove that the quotient group is isomorphic to, the symmetric group of order , and is a semidirect product group of with the classical binary simplex code in the linear case. Finally, we generalize a result due to Calderbank et al..

本文刻画了商群与集合的关系，给出了一个确定集合中那些与共轭的元素的方法，还证明了在线性情形下，商群与阶对称群是同构的，而且是与经典单形码的一个半直积，并且推关广了Calderbank等人的一个结果。

We showed that if G is a non-perfect 11-decomposable finite group, then G is isomorphic to an Abel group of order 121, or a non-Abel group of order pq, here p, q are primes which satisfy p-1-=10q or p=11, q=,r is a prime, too.

在本章中主要证明了，11-可分解的有限可解群，必同构于121阶Abel群：或同构于pq阶非Abel群，其中p，q均为素数，且满足p-1=10q或p=11，q=？

In chapter 2, we prove that an abundant semigroup satisfying the regularity is a locally E-solid semigroup if and only if it is an E-local isomorphic image of some abundant Rees matrix semigroup AM over an E-solid abundant semigroup with entries of the sandwich matrix P being regular elements of T.

第二章，我们证明了满足正则性条件的富足半群是局部E-solid(quasi-adequate，R~*-unipotent)半群当且仅当它是某个富足Rees矩阵半群RM的E-local同构像，其中sandwich矩阵的P元素是T中的正则元。

The main difference is the core business of information products group, responsible for the personal computer marketing information products and services; electronic services group, to complete the advanced information technology and management of the giant structure, providing customers with innovative Juju high economic efficiency of micro-electronic Services and solutions, management and investment management group, responsible for creating the best interests of long-term investment, stability, Acer's business environment and help Acer e-Business cause of expansion.

Although many general results in K〓 and relative K〓 theory have been obtained, the determination of structure and the computation of K〓 groups and relative K〓 groups are very difficult.

对于K〓群及相对K〓理论的一般性研究也已取得了较多的成果，但是K〓群及相对K〓群结构的确定和计算却比较困难。
