Nm~3,μ= 4.836 mm~(-1), F(000)= 677, R = 0.0403, wR = 0.0673. Both of the complex adopt distorted trigonal bipyramidal geometry, with the basal plane defined by the SS atoms of the tridentate ligand and the oxo-group. The N of the tridentate ligand and the S of the monodentate ligand occupy two apical positions. Ionization of the sulphur atoms leads to a neutral compound.

As in recent years although EB curing equipment in terms of price has a high degree of reduction, but with a one-time investment in equipment still larger; the price of EB inks are the highest price in ordinary ink; EB curing applies only to the plane, and curing coatings cure product of geometry are restricted; EB inks for an important characteristic is that it has good resistance to resistance, but this abandoned business card printing and membership card when making products become difficult to deink or interfere with the recovery of a factor, so printing recovery must also be done according to new research.

如近年来EB固化摆设虽然在代价上有很不小水平的贬矮，但是其摆设一次性加入还来较不小；EB油不朱的代价仍比别致油不朱的代价矮；EB固化仅合用于平面的涂层固化，因而固化产物的多少轮廓受到不拘；EB油不朱的一个轻给共性不离是它有精良的耐抗性，但这在保持制卡和会员卡制息品发放时则成为脱不朱难、帮助发放的一个成分，因此在印品发放方面还务必怠工陈的查究。

In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.

本论文的主要研究内容是利用格雷码加线移结构光对物体进行投影，再经摄像机采集到畸变的图像，结合相关算法以实现对物体的三维重构：摄像机采集到的6幅图像序列形成的格雷码将图像空间划分为64个周期，通过20次线条纹的移动完成对整个扫描平面的覆盖，在已获得两摄像机标定参数基础上，结合对极几何原理完成左右图像像素点的匹配。

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.
