Below system of socialist market economy, how to expand communal economy actual strength, the author thinks, the new development form that should explore state ownership actively on one hand and implementation form, should widen on the other hand development train of thought, wide monarch throws channel, take country, collective, farmer, inside endowment foreign capital and urban and rural the guiding principle that goes up simultaneously.

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是靠模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的靠模，加工时把工件毛坯和靠模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动，从而切割出与靠模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作靠模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴，是由前苏联人发明的，我国是第一个用于工业生产的国家，当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型，我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS

This paper is based on the former research taking the No.1 Tong-Lv Bridge as an example; the large universal finite element program Midas/Civil is adopted, a three-dimensional finite element model is established. The static performance, the comparative analysis of influence surfaces, the experimental study and the analysis of a local finite element model of the new style three-span continuous through type bow-string arch bridge is made. With these studies, this paper is aimed at revealing the performance of this kind of construction.

本文在前人研究的基础上，以通吕一号桥为背景，采用空间有限元法对结构形式新颖的三跨连续下承式系杆拱桥的静力性能、影响面比较分析、实桥荷载试验、局部节点分析等进行研究，旨在深入理解该结构形式桥梁的力学性能，为今后相同结构体系桥梁的结构分析提供可以参考的建议。

Foundation of the express railway is the key and weak link in safety system.

路基是高速铁路安全系统的关键和薄弱环节，建在软土上的高填路堤边坡是否稳定，更是直接关系到路基乃至整个高速铁路系统的安全，采用桩—网复合地基形式修建高路堤是一个好办法，这种路堤形式尚不多见。

Zen Buddhism is the Chinese form of expression of Buddhism and it is the important part of our traditional culture.

禅宗是佛教在中国的表现形式，是我国传统文化的重要组成部分，它作为中国文化史上的一种思想现象，在艺术表现内容和艺术表现形式方面给艺术，尤其是文人画带来了深刻的影响。

After basic exchange came into existence, more complex forms developed beyond a basic barter economy, and new forms of risk manifested.

在最基本的交易出现之后，更为复杂的交易形式在物物交换经济的基础上产生，新的风险形式也应运而生。

Furthermore, the burals have represented the mental satisfaction reached by the medium of direct psychological imagination.

各种石器体现出原始祖先对形式的美感从单纯的功利意识逐渐向审美层面过度和靠近；而他们的墓葬形式则显示了他们以自己的主观心理想象为媒介而获得的情感上的满足，即在想象中被赋予的生命意味。

This thesis introduces "total volume method" into VAV control schemes, and analyses its advantages.

本文在进行广泛的文献阅读的基础上，对目前采用主要变风量系统形式、变风量末端形式以及主要的系统控制方法进行了分析和对比，指出了静压控制方式的主要缺陷，进而提出了采用&总风量控制方法&对变风量空调系统进行控制，该方法不再以静压作为调节风速的参数，而是以系统当前要求的总风量来调节风机的转速，并分析了总风量控制方法的优势和特点。

Jazz originates from New Orleans of southern America at the end of 19th century, and is characterized by a strong but flexible rhythmic understructure with solo and ensemble improvisations on basic tunes and chord patterns and, more recently, a highly sophisticated harmonic idiom.
