But in the + moiety, the three benzimidazole rings shared the whole space equally, the dihedral angel among them is about 120°, just like three fan blades of an airscrew, the molecular structure appear gear-like shape.

X-射线单晶衍射测试、红外、紫外等方法确定了三(2-苯并咪唑亚甲基)胺的Fe和Co配合物的结构，由晶体结构发现金属配位情况不同、配合物在结构上存在着差异，Fe为八面体构型，而Co为三角双锥构型；其次，两配合物中的苯并咪唑环间夹角不同，配合物中包含N2和N4的两个苯并咪唑环间夹角仅为9.41(0.11)，几乎构成一个平面，呈蝴蝶形；后者Co三个苯并咪唑环几乎平分了整个空间，它们之间的夹角约为120，呈三扇叶螺旋桨式构型，为齿轮形。

Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR,EC 1.1.1.50 ) from Comamonas testosteroni is an inducible enzyme which catalyzes the oxidation of androsterone with NAD+ to form androstanedione and NADH. 3α-HSD/CR was a member of the SDRs family, whose crystal structure had been solved by X-ray diffraction in 2000. The structure of 3α-HSD/CR is a homodimer which shows a typical pattern of Rossmann-fold structure consisting of βαβ units, and reaveals similarity with other members upon the SDRs family.

中文摘要 3α-Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR，EC 1.1.1.50 )是从Comamonas testosteroni菌体中分离而来的诱发性酵素，利用NAD+为辅因子，将受质androsterone氧化成androstanedione并伴随NADH的生成而完成催化反应。3α-HSD/CR是属於SDRs家族成员之一，其立体结构已经在2000年利用X-ray晶体绕射所解出。3α-HSD/CR在结构上为一同源双聚体，并和其它家族成员一样具有βαβ二级结构所叠合组成的Rossmann-fold特徵。

Based on the similarity of structure between the antifluoride and alkali antimonide, the possible transitions taking place in the Brillouin zone corresponding to the structure in the optical spectra are identified for Na_2KSb,Css_3Sb and K_2CsSb cathode.

利用反荧石结构和其结构的相似性，确定了Na2KSb、Cs3Sb和K2CsSb阴极在光谱结构上对应布里渊区中发生的光学跃迁，发现多碱阴极的跃迁更接近晶态，而Cs3Sb和K2CsSb阴极和非晶态的非常类似，在Na2KSb中出现的来自Δ、Σ方向跃迁形成的极大峰并不出现在Cs3Sb和K2CsSb。

In the rock-soil engineering, the soil pressure caused by slope excavation is very complicate .It not only withes pays to the reinforced structure displacement, stiffness and geological condition, but also related with the excavation method.

岩土工程中，边坡因开挖坡脚岩土体所产生的作用于支挡结构上的土压力情况复杂，它不仅与支护结构位移、刚度和岩土体地质条件相关，而且还在很大程度上取决于施工方法。

One correlate of that axiom is that Creole languages fall outside the class of structurally "normal"/"genetic" languages with "normal"/"genetic" pedigree as defined by the family-tree model of gradual linguistic change / speciation: languages in the standard family-tree (e.g., French) are assumed to have developed gradually from "normal" full-fledged languages (e.g., Latin), not from structurally reduced Pidgins.
