And there is an approximate linear relationship between the momentum of the automatic mechanism and the length of the gas tube.

如β=〓与β=〓相比较（β角单位为弧度，其定义详见正文），前者与后者对应的气室最大压力之比可达65%，而对应的自动机动能之比可达60%；导气管内径对气室内气体压力冲量和自动机动能的影响存在极值点，且该极值点随导气孔的增大而有规律的增大；导气管长度对气室最大压力、压力冲量和自动机动能的影响呈单调递减规律，且自动机动量与管道长度之间近似符合一直线关系。

Due to the influence factors including geological conditions, the pressure of water curtain, air pressure in surge chamber and properties of rock masses and so on are taken into account, the water-air two-phase flow model proposed in this paper may provide a new idea for the design and remediation of the air-cushioned surge chamber.

由于水-气二相流模型可以充分考虑调压室地质条件，水幕的压力，气室气压及围岩性质等因素的影响，为空气损失评估、水幕设计及对漏气严重的调压室进行修补提供了新的研究思路。

We use GRIN lens as collimating or focusing lens for transmission gas cell ,and a method that using cascaded GRINLens couple to increase the optical path length is presented. Using this method ,the detection sensitivity of the gas cell has been greatly increased.

利用自聚焦透镜作为光纤准直透镜和聚焦透镜，应用于透射型气室，并提出了在透射式气室中将多对自聚焦透镜组串联用以增加吸收光程的方法，用该方法可以明显提高气室的检测灵敏度。

The belt of this conveyor is supported by the pressure air rushed out of the holes of the air chamber into which air is blowed continuouly in a certain amount and pressure by a fan and wind adjusting mechanism. The conveyor driven by a drive mechanism conveys materials on an air cushion, thus fluid friction is in place of rolling friction between belt and support roller, reducing the friction drag.

本机是通过风机和风量调节机构连续向气室供给一定压力和流量的空气，空气通过气室盘槽上的排气孔在胶带与盘槽之间现成气垫支承，胶带在传动机构的拖动下，在气垫上运行，以流体摩擦代替托辊式胶带输送机的滚动摩擦，减少阻力，达到输送物料的目的。

After the leak detection valve and the chamber evacuation valve are closed we vent the chamber and we draw off the helium.

在泄漏检测阀门和气室抽真空阀门关闭后，我们给气室放气并排除氦气。

After starting the engine, the engine intake manifold vacuum at rising, with the attendant vacuum booster true air chamber, the application of the vacuum chamber were up and ready to work in a state of readiness.

发动机起动后，发动机的进气歧管处的真空度上升，随之，真空助力器的真空气室、应用气室的真空度均上升，并处于随时工作的准备状态。

There is a hole in the shaft through which the air from the upper chamber enters the lower one.

腔筒中心有一孔道，压缩空气就是由此从上气室进入下气室的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
