MGM is introduced to solve field distributions in 3-D electron optical systems. The difference equation, the discrete form of Laplace's equation, is deduced in 3-D Cartesian coordinates. In view of the smooth effect, MGM combines Gauss-Seidel iteration with a technique known as coarse grid correction. Formulae for restriction and prolongation are deduced and expressed in terms of tensors.

In addition, some experience formulas for them are regressed. The third chapter establishes a unified S-N curve equation to calculate multi-axial fatigue ultimate strength of concrete considering both the effect of confinement and minimum/maximum stress ratio, based on the triaxial fatigue test data in this paper and the test results under uniaxial and biaxial fatigue loading in previous literatures. Moreover, the consistency of calculating condition fatigue ultimate strength with fatigue life distribution and initial ultimate strength distribution is analyzed.

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。

The OSIRIS telescope is a Three Mirror Anastigmat consisting of conic surfaces: a concave hyperbolic primary, a convex parabolic secondary and a concave spherical tertiary.

OSIRIS 望远镜是一个三反射系统，由一个凹双曲面主镜，一个凸抛物面次镜和一个凹球面三镜。次镜 M2在中间，主镜 M1和三镜 M3呈离轴配置。

The Third Lateran Council (1179), convoked by Pope Alexander III, ended the schism (1159-77) of the antipope Callistus III and his predecessors.

第三lateran会（ 1176 ），召集了由教皇亚历山大三世，结束了裂（ 1159年至1177年）的对立教宗callistus三和他的前辈。

V-triazole was firstly prepared by Von Pechmann and Ven Baeyer in 1888, and the study on its derivatives has been very active in the past century.
