On the tire with an inner tube, the valve is mounted on the tube.

有内胎式轮胎气门是直接做在内胎上的，无内胎式轮胎的气门安装在轮毂上。

As this happens, the intake valve closes. The exhaust valve is also closed, so that the cylinder is sealed.

同时，进气门关闭，排气门也关闭，所以这时的气缸是封闭的。

This action could open an inlet valve for an intake stroke, or open an exhaust valve for an exhaust stroke.

这过程能使进气门在进气行程打开，或者排气门在排气行程打开。

The experimental results show that exhaust valve closingtiming has a great influence on internal exhaust gas recirculation ratio and HCCIcombustion. While inlet vavle opening timing has a little influence on HCCIcombustion.

试验结果表明，排气门的关闭时刻对缸内的残余废气率影响大，因此对HCCI燃烧影响大，而进气门的开启时刻对HCCI燃烧的影响较小。

The valve bridge may be operatively connected to first and second engine valves at its first and second ends, respectively.

气门桥分别在其第一端部和第二端部可操作地连接至第一和第二发动机气门。

The downward-moving side of the rocker arm pushes on the valve stem to open the valve.

摇臂向下移动的那一边推动气门杆以打开气门。

Current, the gasoline engine that Feng Tiansheng produces has used VVT-i technology entirely, develop; of double VVT-i gasoline engine the product of this cropland uses VVT-i technology generally already also, the 8th generation thinks of the 1.8L gasoline engine of the city has been the 3rd phase to change spiracle is phasic and change spiracle rises Cheng

目前，丰田生产的汽油机已经全部采用VVT-i技术，并开发出双VVT-i汽油机；本田的产品也已普遍采用VVT-i技术，第8代思城的1.8L汽油机已经是第3阶段的变气门相位和变气门升程的

Methods The necrophagous fly L. sericata were reared at constant temperature of 20 ℃, 24 ℃ and 28 ℃ respectively and were tempted to lay eggs with lean pork. One Sample was taken at 12 h intervals till 50% of the larvae were in pupae stage. Then, the anterior spiracle, posterior spiracle and cephalopharyngeal skeleton were investigated through digital image processing combined with morphologic observation.

在20 ℃、24 ℃和28 ℃下饲养丝光绿蝇，瘦猪肉诱其产卵，每隔12 h取样1次，直至50%以上幼虫化蛹为止，采用形态观察与图像分析相结合的方法对幼虫前气门、后气门、头咽骨进行观察研究。

According to the opening or closing spiracle , a typical discontinuous gas exchange cycle has three distinct phases: the closed period with little or no external gas exchange, the flutter period during which oxygen enters tracheae and little CO (2) escapes and the open period during which lots of CO (2) escape.

根据气门开闭，一个典型的不连续气体交换循环(discontinuousgas exchange cycle， DGC)可以明显分为3个阶段：关闭阶段，极少或没有气体交换；颤动阶段，气门迅速微开和关闭， O2进入气管，少量CO2释放；最后是开放阶段，大量的CO2释放。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
