In order to develop an useful synthestic process, we have synthesized amides with various substitutents. The isoquinoline skeleton was constructed through Bischler-Napieralski reaction, followed by asymmetric reduction of the imine intermediates with a Ru complex to form the only chiral center. Finally, we connected the two phenyl groups by Heck reaction and effectively obtained optically active aporphine alkaloids.

为了发展一套实用的合成方法，我们首先制备於苯环上具有不同种取代基的苯乙醯胺，接著透过Bischler-Napieralski反应进行分子内合环，并利用钌金属对亚胺中间体进行不对称的还原反应，建立出产物中唯一的光学活性中心，最后再利用Heck反应连结两个苯环，就可以顺利得到具有光学选择性的阿朴吩类天然物。

We introduce two pyridinedicarboxylate (2,5-H2pdc and 2,6-H2pdc) ligands, under hydrothermal or solvothermal condition, to yield 7 complexes with InCl3. Complex 17 presents a rare example of chiral binodal (4,8)-connected lattice with self-interpenetration.

选择了两种吡啶二羧酸配体： 2，5-吡啶二羧酸(2，5-H2pdc)； 2，6-吡啶二羧酸(2，6-H2pdc)和InCl3反应合成了七个配位化合物其中17表现了一例少有的手性的(4，8)连接的双节点自穿插拓扑结构。

In the complex, the centrosymmetric dimeric [V2O2](superscript 4-) unit connected to neighboring Cd(superscript 2+) through the phosphonate group, forming 2D network.

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

Curriculum is a complex system. It is hoarily connected with many subjects such as philosophy, psychology, cult urology, sociology etc; however, the closest and the most intricate relation to it should be the teaching theory.

课程作为一个复杂的体系，与哲学、心理学、文化学、社会学等诸多学科有着久远的渊源，但其中关系最为密切、最为错综复杂的，当属教学论。

X-ray crystal structure analysis for complex 1 reveals that the copper ion is penta-coordinated by a D-and a L-diamine ligand, and two copper ions are bridge-connected by two cyanides from [Fe6](superscript 3-) in axial position.

晶体结构分析表明，化合物1中Cu离子处于五配位的配位环境，分别和1个D-La，1个吞L-La及[Fe6](上标 3-)中的l个氰基配位，2个Cu离子通过[Fe6](上标 3-)桥联。

Traditionally, a surface is usually scatted in an array of 3D data points which are topologically connected by rows and columns to form a rectangular mesh. This method can't meet the requirement of description and measurement for some complex surfaces. On the basis of tracing border points, a new method is proposed to deliver 3D data points of surfaces, which are topologically constructed with optimum rectangular and triangular mesh. In order to measure surface efficiently and safely with NC machine, an optimization of measurement paths is proposed to avoid interference between the measuring tool and the surface with holes. The curve design is the basis of surface modeling.

数控测量技术的发展为测量自动化、集成化、智能化提供了可能，而对于复杂曲面的自动测量规划则是测量技术中的难点问题，平行截面等数目测点分布和四边拓扑测点分布规划方法，不论在测点分布的合理性上还是在网格结构的优化方面，均难以满足形状或边界较复杂曲面的离散化描述和曲面造型的要求，为了实现任意拓扑曲面的自动测量，本文对复杂曲面的合理离散化描述和自动测量问题进行了研究，提出了基于边界跟踪、优化网格的测点自动分布规划和四边、三角混合网格的生成方法：同时对具有孔洞或测量干涉凸台等非完整曲面的测量路径优化问题进行了研究，提出了路径优化方法。

The Ink Jet Printing industry emerged around the early 1970s. It is still populated by a number of specialist companies which own, develop and licence the technologies and supply the equipment. They are connected to their end-users by a complex network of dealers, distributors and licensed printer manufacturers. They are supported by ink manufacturers, which in some cases have been bought into the company. This is a study of an enterpise spun-out from Cambridge Consultants Ltd using a new technology, ink jet printing.

喷墨印刷工业露出冰山一角在20世纪70年代，现在仍然被一些专门的厂商所组装，这些厂商拥有，发展，注册这些技术的专利，并且供应这些设备，他们和最终用户通过复杂的经销商网络，发行人和许可打印机制造商，他们被油墨厂商所支持，在一些情况下，油墨厂商被买进公司，这个是一个从剑桥顾问公司使用新喷墨印刷技术衍生出的公司。

Program is positioned as the final complex for anumber of problems, connected with the record of optical drivein diverse variants , a number of musical compact of disks, and also reserve data copying .

计划是定位为最后复杂的一些问题，与记录光盘驱动器在不同的变种，一些音乐紧凑的磁盘，也储备数据复制。

Fixed satellite servicenetworks are mainly intended for long-distance operation of telecommunications networks,FSS satellites are employed to relay signals between large,complex,and expensive Earth stations,which are connected to the terrestrial telecommunications network.

固定的卫星系统网络主要打算供长距离的电讯广播网的运转使用，FSS卫星用来转播大的，复杂和昂贵的地面电台的信号，连接在陆地电讯网上。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.
