Let L and P be Lie color algebras and let M be a graded module over P, the crossed modules which make M as their kernal and P as their cokernal are considered. It is shown that under a suitable equivalent relation, there is a bijection between the set of the equivalent classes CML and the homogeneous components of degree zero of H~3.
从交叉模的定义出发,对于给定的Lie color代数L,P以及阶化P模M,考虑所有以M为核、以P为余核的L的交叉模,在这些交叉模之间定义了一个等价关系,由此得到交叉模的等价类集CML,证明了CML与三维上同调群H~3的零次齐次部分之间存在一一对应,从而可以利用三维上同调群对Lie color代数的交叉模进行分类。

Not every subgroup of a D-group is also a D-group. If a subgroup is a D-group we call the subgroup "sub- D -group." The "commutator ideal" of G is the smallest sub-D-group containing its commutator subgroup. We found that the commutator ideal can be viewed as a finitely generated module over a ring when G is a finitely generated metabelian D-group.
并非每个子群都是一个可除群,若一个子群是可除群,我们称之为子可除群(sub-D-group),而G 的交换子理想则是在G中包含其导出群的最小子可除群,我们发现当G是一个有限生成亚交换可除群时,其交换子理想是一个有限生成模。

There is no significouldt variation between the function of Method 1 and 3 in the indexes of digestive and absorptive function,except the effect on body weight and food intake;as well,model 2 shows no significouldt influence on the indexes besides body weight lose.1.4 ConclusionsContrast the three modeling methods,model 3 is the most obvious and steady method for the establishment of deficiency of spleen YANG.2 comparison on the efficacy of Lizhong Pills influenced by dried ginger and its different components on digestive and absorptive functions and energy metabolism2.1 ObjectivesThis research was designed to observed the different influences of Lizhong Pills formula on the models,which contains dried ginger or its main group of components(volatile oil and water solubles).It would be explored from two levels of material base,single herb dried ginger or its different components,to confirm that the whole effects of Lizhong Pills do mainly depend on its main herb dried ginger in the formula just as the traditional acknowledgement in TCM.Further more,the connotative meaning of dried ginger used as the main herb in Lizhong Pills egthe aspect of pharmacology and chemistry would be preliminary revealed.2.2 MethodsEach group of model rats of deficiency of spleen-YANG were to be duplicated by method 3 for 14 days,and be treated by corresponding drug samples for 8 days.
