- An inward stroke, especially a piston stroke moving away from the crankshaft. 内冲程向内的冲程，尤指从曲轴移回的活塞冲程
- BDC - Bottom dead center. The bottom-most position of the engine piston stroke. 下止点。引擎活塞在燃烧推动下到达的最低位置。
- With each piston stroke, a small quantity of atmospheric air or gas is pumped into the discharge air vessels. 在活塞的每个冲程中，将少量的空气或气体输送到空气槽内。
- Reciprocating pumps convert rotary motion to linear motion. Pump speed in rpm determines the pumps output volume for any given combination of cylinder bore and piston stroke. 循环泵将曲轴旋转运动转化为柱塞的直线运动。泵速转每分钟决定了任何气缸和活塞组合的排泵量。
- By controlling the piston stroke and the resistance on flow Passage,the fluid lift height and the pump speed can be controlled,thereby ideal lifting effect can be achieved. 通过控制活塞行程及泵内流道阻力，从而控制泵举升液柱的高度和泵的运行速度，取得理想的举升效果。
- Taking a five-story frame structure as an example, the influence of the piston area, piston stroke, accumulator volume and oil elastic modulus on the systems control effect and energy transition efficiency are discussed in detail. 详细讨论了四个主要参数的变化对振动控制效果和换能效果的影响，这些参数包括隔震换能系统的活塞面积，活塞最大行程，蓄能器体积和油液弹胜模量等。
- The power production cycle consists of four piston strokes in an engine. 产生动力的循环由发动机内活塞往返四个行程组成.
- Diesel and gas-burning engines can be divided into two groups based on the number of piston strokes per cycle, either four or two. 根据每一次工作循环活塞运动的行程数，柴油发动机和汽油发动机可以分为两种类型，四冲程或者两冲程。
