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。

From this, must combine rural society to develop integratedly, force of stimulative surplus labor is orderly billabong.

由此 ，必须结合农村社会综合发展，促进剩余劳动力有序分流。

In order to elucidate the role of LKBl in controlling bionomics of tumor.the following studies have been done.

由此推测，抑癌基因LKB1对肿瘤细胞中VEGF的生成，亦可能存在着一定的调控作用。

Based on the study of biostratigraphy and anoxic eventstratigraphy, we propose that the Qingshankou Formation may correspond to the oceanic anoxic event at the CenomanianTuronian boundary in the Cretaceous, and the age of the Qingshankou Formation in the Songliao Basin is the Late Cenomanian to the Early Turonian.

结合生物地层研究成果，认为青山口阶下部曾发生过古湖泊缺氧事件，其层位大体可与白垩纪古海洋CenomanianTuronian界线事件层进行对比，由此提出了松辽盆地青山口阶下部的时代归属于晚白垩世Cenomanian晚期-Turonian早期的新观点。

By comparing the characteristics between induced electrical field and steady magnetic field using time vector method,the corresponding relationship between them was found out and the "Biot-Savart s" law of induced electrical field presented.

利用矢量分析的方法对比了感生电场和稳恒磁场的特点，找出了两者的对易关系，由此给出了感生电场的"毕奥—萨伐尔"定律。

It is demonstrated that according to the hydrothermal biotite and the igneous biotite, the magmatic source rocks and the environments of cooling crystallization can be distinguished.

文中还论证了应用矿床中的热液黑云母和岩体中的岩浆成因黑云母的x/x和x/x等成分指标，由此可识别岩浆源岩性质和岩浆冷却结晶的物理化学环境。

From these results, we concluded that the BIP protein is a novel MV receptor in marmoset B-lymphoblastoid cells.

由此充分证明bip是存在于绒猴类B-类淋巴母细胞中的麻疹病毒新的细胞受体基因。

Their feet were thought to be very much like ours, suggesting they had mastered bipedalism.

此前，研究人员曾认为，粗壮型南猿的脚和我们的很相似，并由此认为他们可以熟练地用两只脚行走。

Their feet were thought to be very much like ours, suggestingtheyhad mastered bipedalism.

此前，研究人员曾认为，粗壮型南猿的脚和我们的很相似，并由此认为他们可以熟练地用两只脚行走。

Applyingthe sufficient and necessary condition of biquadratic Bézier patch being non-negative,a method is presented to see whether two points are the closest points between twobiquadratic NURBS surfaces when the two points are respectively on the two surfaces. Based on the method, the surface split algorithm is improved while the surfaces arebiquadratic NURBS surfaces.

本文利用双二次 Bézier 曲面为非负的充要条件，提出了分别位于两张双二次 NURBS 曲面上的点是否为这两张曲面间距离最近的点的判别方法，并由此在双二次 NURBS 曲面的场合对计算最短距离的曲面分割法作了改进。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
