The results show that there are two types of pore in the sintered alloy, i.e., one is coarsen pores with diameter more than 30μm, the other is thin pores with diameters less than 10μm. These two types of pore evolve from two voids in green compacts respectively.

研究结果表明：合金中的孔隙主要有2种类型，即粒径为30μm左右的大孔隙和粒径在10μm以下的小孔隙，这2种孔隙分别由生坯中的2种主要间隙在烧结过程中演变而成。

The paper includes:The author calculate the structures inner force and displacement of the free end , analyze the influence of the height and the value of pretress of cable by making use of ANSYS 9.0 soft, pose the concept of critical prestress,conclude the function relation between displacement of the free end, initial strain and the height of cable ,analyze the dynamic properity and point out that Newmark-β method should be adopted when we analyze the dynamic properity of the cable-stayed spatial structure with direct integral test to guarantee the contribution of high mode,finally conclude the functional relation among coefficient of earthquake inner force, initial strain and the height of cable, wish to get some helpful conclusion applied to cable-stayed spatial truss design.

本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

According to the present situation of Guangzhou subway line 4, a control system based on programmable logic controller is presented, which can be used to alternate the working mode of subway locomotives between contacting collector and pantograph for collecting current.

介绍受电弓和受流靴这两种受流器各自的优缺点及工作原理，并针对广州地铁4号线运行中的实际情况，提出了受流方式转换过程的技术要点，设计了一种由可编程序控制器为控制核心的系统，该系统可控制地铁列车在两种受流方式之间的转换。

Banker: There are two other modes. One is collocation; the other is letter of Credit.

Now Sinicized Marxism has three value appeals of, namely, politics, discipline requirement and life demands, which have one common social foundation of the establishment and development of market society, making the possibility of commensuration between the three value appeals.

当下，马克思主义中国化正以三种价值诉求呈现出来，即政治诉求、学科要求和生活需求。三种价值诉求具有一个共同的社会基础，这就是市场社会的建立与发展。这种共同的生活基础为三种价值诉求之间的通约创造了可能性。

Languages that are used for commination among speakers of different languages are called lingua francas. This name derives from a medieval trade language used in the Mediterranean region and based largely on Romance languages but also containing elements of Greek, Arabic, and Turkish.

遇到这种情况时，他们一般采取以下三种方法之一来对付，即：(1)外来人学习说当地主人的语言，(2)他们使用当地作为贸易用的第三种语言，或(3)产生一种新的语言----这种语言是由使用者的不同母语的一些成分合成的。

Comparison of reaction for resistance spectrum to 20 strains including 10 Philippine races, 3 Japanese races, and 7 Chinese pathotypes between CBB23(carrying Xa23 )and IRBB21(carrying Xa21) was made.

比较了CBB23 (携Xa23)和IRBB21 (携Xa21)对20个菌系包括10个菲律宾小种、3个日本小种和7个中国病原型代表菌系的抗谱， Xa23抗所有20 个菌系；Xa21 抗19个菌系，对菲律宾10号小种则高度感病。

This paper studys the stability of nonlinear systems in two particular critical cases. In a case, the linear systems at the equilibrium point of interest is assumed to possess a simple zero eigenvalue. In the other case, it is assumed to possess a complex conjugate pair of simple pure imaginary eigenvalue.

本文基于中心流形定理研究了非线性系统在两种特殊临界情形下的稳定性问题，一种是与它相应的线性系统在平衡点仅有零特征根，另一种是与它相应的线性系统在平衡点仅有一对共轭的纯虚数特征根。
