1·Should it have a long or short piston?
活塞应该长还是短？
2·The new series also includes a piston design that makes digressive forces for added pitch and roll control. This helps with performance over rough terrains and on off-road surfaces.
新系列还包括一个活塞设计，它可降低阻力，增加间距和滚转控制，这有助于军用车辆在崎岖的地形和越野路面的表现。
3·My earliest memories are of pointing to the sky, having detected the far-off drone of a piston engine.
我能回忆起的最早的事情就是指着天空，耳边传来远处的活塞引擎的轰鸣声。
4·We sometimes use this analogy of a kid's game called 'booby trap' where you have a bunch of little blocks and there's a spring piston and it pushes on them.
他说，“我们有时候把地震和小孩子们玩的一种叫做‘陷阱’的游戏做比较。”你有一些小砖块和一个活塞弹簧，弹簧挤着砖块。
5·There's my piston right there.
现在我的活塞在这里。
1·Featuring a spring piston firing mechanism, the sniper rifle is almost silent when fired.
采用弹簧活塞式发射装置，狙击步枪射击时几乎无声。
2·Polmar agrees, and points out that the piston engines used in conventional light planes are ruled out for other reasons: they would fail if any water leaked into the cylinders.
对于这一点，波尔玛也赞同，并且指出，用于常规轻型飞机的活塞式发动机行不通还有其他原因：要是有水渗入气缸内，它就不能工作了。
3·Therefore, it has a fast response electric actuator and the executing agency of the thrust piston big and so on.
因此，它具有电动执行机构的快速响应性和活塞式执行机构的推力大等优点。
4·Because of its excellent part load efficiency, many compressor unit is used mainly in the occasions for large displacement in high pressure piston compressor applications.
由于其出色的部分负荷效率，多压缩机机组主要应用于的场合为大排量中高压活塞式空压机应用领域。
5·The use of pneumatic actuator cylinder piston and crank conversion structure, output torque, small size fine.
气动执行机构采用活塞式气缸及曲臂转换结构，输出力矩大，体积精小。
