活塞

• He pulled a faulty piston out of the machine and inserted the pen in its place .
  他从机器里取出一个坏了的活塞，把自来水笔塞进原来的地方。
• The plunger is forced to undergo a simple harmonic vibration parallel to the direction of the tube .
  活塞在平行于长管的方向被迫作合谐摆动。
• The upward pressure on the piston is then greater than the downward pressure by a finite amount .
  作用于活塞朝上的压力比朝下的压力大一定值。
• When the hydrodynamic front reaches the ambient medium it acts like a fast-moving piston .
  当流体力学波阵面抵达周围介质时，它像一个运动迅速的活塞。
• When the stopcock is opened, water flows from the top of the warmer column into the colder column .
  打开活塞后，水即由较热的水柱顶端流入较冷的水柱。
• It is also generally conceded that wankel engines are quieter than comparable piston engines .
  转子发动机比通常的活塞式发动机噪音小也是大家所公认的。
• Consider a container whose volume can be varied, such as a cylinder provided with a movable piston .
  现在，我们考虑一体积可变的容器，例如一只具有可移动活塞的气缸。
• The piston moves up and down in the piston chamber primarily in response to changes in intake manifold vacuum .
  活塞主要因进气歧管真空度的变化而在活塞腔内上下移动。
• As the piston descended, a ratchet engaged the piston rod and engine shaft and thus power was transmitted .
  当活塞下行时，棘轮连接活塞杆和发动机轴，因此将功率输送出去。
• A fresh charge of air-fuel mixture will be drawn into the cylinder as the piston moves down toward .
  随着活塞朝下止点的向下运动，一些空气燃料混合气的新鲜充量将被吸入气缸。
