查询词典 classical groups

Multi-hydrogen-groups on the catalyst make deep hydrogenation or hydrogenolysis take place. Adding promoters in the copper-substrate and zinc-substrate catalysts helps to formatting the multi-hydrogen-groups on the surface of them.

通过助催化剂的添加，在Cu基催化剂和Zn基催化剂上产生多氢吸附集团，可以改善催化剂深度加氢或氢解反应的性能，以有效地调控深度加氢反应。

In nonionic detergent s, hydrophilicity is based on the presence of multiple hydroxyl groups or other hydrophilic groups.

在非离子洗涤剂中，亲水性是基于多羟群和其它亲水残余物的存在而产生。

In non ionic detergents, hydrophilicity is based on the presence of multiple hydroxyl groups or other hydrophilic groups.

在非离子洗涤剂中，亲水性是基于多羟群和其它亲水残余物的存在而产生。

Results Contrast vision showed significant differences among the subjects in the four groups(P.05);Night vision changed obviously in the two older groups(P.01);The recovery course from dazzling prolonged correspondingly with the increase in age.(P＜0.05 or P＜0.05);With age increasing,the diopter of these subjects had a tendency of hypermetropia from myopia.

结果 5a后，各组对比视力差异有显著性(P＜0.05)；2个高年龄组的昏暗视力在5a前后变化非常明显(P＜0.01)；各年龄组的眩目恢复时间均随年龄的老化而显著延长(P＜0.01或P＜0.05)；随着年龄的增长，人眼的屈光度有由近视向远视变化的趋势。

The expression of GLP-1 mRNA in the test groups and the normal groups was detected in rat hypothalamus.

对照组和缺氧组大鼠下丘脑中均存在GLP-1 mRNA的表达。

Further,we findalso that groups in Saito's results may be replaced by right groups;secondly we mainly investigatethe semidirect products and wreath products of P-regular semigroups;Finally we shallcharacterize the sandwich matrice of completely simple P-regular semigroups,and investigate thestructure of P-regular semigroup whose C-set satisfies a permutation identity.

在这一章中，首先指出Saito在研究半群的半直积和圈积时，对S的限制是不必要的，证明了Saito结果中群可换为右群；其次，研究P—正则半群的半直积和圈积；最后刻划了完全单P—正则半群的夹心阵和C—集满足置换恒等式的P—正则半群的结构。

Simons [30] proved the non-existence theorem for stable integral current in acompact Riemannian submanifold isometrically immersed into a unit sphere andvanishing theorem for homology groups. In 1984, Y. L. Xin [47] generalized theLawson-Simon\'s nonexistence theorem for stable integral current and vanishingtheorem for homology groups to the case of compact submanifolds in Euclideanspace, and gave several important applications.

Simons运用Federer-Fleming存在性定理[19]和几何测度论中变分技巧证明了单位球面中紧致黎曼子流形上稳定积分流的不存在性定理和同调群消没定理[30]。1984年，忻元龙将Lawson-Simons稳定积分流的不存在性定理和同调群消没定理拓广到了欧氏空间中紧致子流形的情形，并给出了若干重要的应用[47]。1997年，K。
