1·This paper develops the control system of electronically controlled throttle with high speed on off valve.

研究了一种利用高速开关阀对节气门进行电子控制的系统方案。

2·The electronically controlled hydraulic actuator is used to control the throttle controlled by high speed on off valve.

使用电液式执行器作为节气门控制的执行机构，利用高速开关阀对执行器进行连续的流量控制。

3·A new kind of electro hydraulic on off valve is expatiated on for fuel injection system of electronic controlled diesel engine.

阐述一种用于柴油机电控喷油系统的新型电液开关阀。

4·Design of the system and analysis of its performance are followed by simulation. The results prove its responding characteristic superiority to electromagnetic on off valve.

通过系统设计、性能分析以及模拟计算，结果表明，该阀的响应特性明显优于电磁开关阀。

5·The design incorporates a channel thin enough to become entirely devoid of carriers (ie, free electrons or holes) when switched off, thus acting as a valve, yet full of them when switched on.

这一设计包含了一条足够细的隧道，当它关闭时，里面完全没有载流子(电子或空穴)，当它打开时，里面便充满了载流子，起到了阀门的作用。

6·Start the water flowing by turning off the water intake valve at the tank and turning on a hot-water faucet.

要使用热水槽里的水，首先确保电或天然气已经关掉，在槽的底部把管子打开，通过关掉槽里的进水阀，打开热水水龙头，让水开始流出来。

7·The relief valve may be serviced while on or off the backflow preventer valve.

可以在防回流阀上维修安全阀，或将其从防回流阀拆卸下来维修。

8·A new kind of hydraulic high-speed on-off valve with giant magnetostrictive actuator and cone valve structure is presented.

介绍了一种新型的液压高速开关阀，它采用了超磁致伸缩驱动器和锥体式阀芯结构。

9·As described earlier, the electrical current to the solenoid of a proportional valve needs to be regulated and not just simply switched on or off as is the case with a conventional valve.

作为简单描述，提供给比例阀电磁铁的电流需要被调节，不象应用常规阀的时仅有开关通或断那样简单。

10·Close shutoff valve No. 2 then shut off valve No. 1 on test assembly.

关闭2号关闭阀，然后关闭测试总成上的1号阀门。
