机械装置

For a long period, Xinxiang factory always adopted common design and analogy design, so result in products with such characteristics include ponderosity, absonantconfiguration, high cost and low efficiency, also caused interference of link mechanism during operation, and induced the dig force not reached the nominal specification.

长期以来，由于该厂对工程机械的设计一直采用常规设计和类比设计为主的设计方法，故造成其产品不但粗大笨重、结构不协调、成本高及生产效率低，而且还造成装载机的工作装置在作业过程中连杆机构的相互干涉，致使装载机的掘起力未能充分体现出发动机的动力。

Then the developments of the thermoacoustic machine are reviewed. The thermoacoustic theory is introduced from different points of view. Two typical style of thermoacoustic engine are discussed, followed by thermodynamic circle, principal equations, fluid network principle and oscillation theory.

本文简要回顾了热声学的历史和研究现状，并从几个不同的角度对热声机械的基本原理进行了简要介绍，接着对二种典型形式的热声发动机装置进行了介绍，然后介绍了热声热机的热力循环、基本方程以及流体网络理论和振动理论。

The flocculation mixer is flocculation pool mechanical rabble device , it is used for the waste water treatment mixing process mainly.

絮凝搅拌机是絮凝池机械搅拌的装置，它主要用于废水处理的搅拌过程。

Main and slave rails are chose with high strength material. Its top and sides are all manufactured in very good surface. The precise rack is at main rail.

导轨采用高强度热处理加工路轨制作，导轨的顶面和侧面都经过精密机械磨削加工，在导轨外侧面装置精密齿条。

For those who were born in the late 1970s, electronic devices were something exciting and inspiring back then. In the integrated installation "Goodbye Semiconductor", there are dozens of semiconductor radiogram, television, electronic organ, and synthesizer. They are all Peng Lei's personal collection. He enjoys the simple carnival feeling and the sense of security embedded in the design style. These products made in a transitional period are displaced on the floor of a separate room. When all these devices were turned on, the noises from the old days mixed up together and integrated into an "individual happiness", while the revolving color light and mirror-like wall created a chaotic visual effect for the noises.

对于出生于70年代末的人而言，电器机械在当时是让人兴奋和充满想象力的物质，在综合装置作品"再见半导体"中，十几件八十年代出产的半导体收音机、电视、电子琴、合成器都是彭磊的收藏，他喜欢它们简朴的狂欢气息和设计形式下的安全感；这些过渡时期的产品摆放在一个独立的小屋地上，当它们同时打开，来自旧时代的混音彼此嘈杂着组合而成了一件"私人乐事"，彩色旋转灯球和镜反射般的墙面增加了声场的视觉混乱效果。

A remote-control device for switching a television set on and off and for changing channels.

在线路中阻断或改变联系的机械的电力的电子的装置。

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.

为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压，分闸时易重燃及不可频繁操作，而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题，提出一种基于新型高压投切开关的高压动态无功补偿装置。

Safety protection device is one of the most important components for moving AGV.

安全保障装置是AGV作为运动中的动作功能机械的重要组成部分。

The sandfish lizared, which lives in North Africa and the Arabian peninsula, could also give clues to cheaper ways to cut friction in mechanical and electrical devices than costly silicon carbide or crystalline diamond.

生活在北非和阿拉伯半岛的一种蜥蜴也提供了一些线索，让人类可以通过比碳化硅和金刚石更为便宜的方式，降低机械和电子装置内部的摩擦。

He has given demonstration on early warning system for earth quakes and Tsunami to several students, engineers, scientists and to seismologist. They all appreciated his innovation and mechanism of his instruments.

他已经给一些学生，工程师，科学家和地震学家对地震和海啸的最初警示系统作了示范，他们都非常欣赏他的创新和装置的机械构造。
