查询词典 g

Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。

If for any uv∈E, C_u≠C_v, then we callσis a k-adjacent vertex distinguishing incidence coloring of G andχ_=min{k| there exists a k- adjacent vertex distinguishing incidence coloring of G} is the adjacent vertex distinguishing incidence chromatic number of G.

若对任意uv∈E满足C_u≠C_v，则称σ为G的k-邻点可区别关联着色，并称X_=min{k|存在G的k-邻点可区别关联着色}为G的邻点可区别关联色数。

A finite p-group G is called LA-group, if the order of G divides the order of the automorphism group of G.

称有限p-群G是LA-群，如果群G的阶能整除群G的自同构群的阶。

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。
