活塞行程
1.
The paper analyses several questions of annular BOP design which must be paid attention, for example, the determination of piston stroke; the stroke mating of piston and entity; and the sealing between piston and entity.
在设计过程中,活塞行程的确定、活塞与本体间的行程配合、活塞与本体间的密封等都是必须重视的问题。
2.
Since both the structure and the operating parameters of a d iesel engine change nonlinearly,the heat load and heat rad iation area are d irectly influenced by the ratio of piston stroke to cylinder d iameter(S /D).
柴油机的结构及工作参数均为非线性变化关系,活塞行程与气缸直径的比值(S/D)将直接影响柴油机的热负荷与散热面积。
3.
A method was developed to measure the piston stroke and to determine the static and dynamic characteristics of a variable displacement compressor.
为获得汽车空调用变排量压缩机稳态和动态特性,提出了一种变排量压缩机活塞行程测量方法并研制出测量装置。
5) piston travel
活塞行程
1.

6) downstroke
[英]['daun,strəuk] [美]['daʊn,strok]
向下行程
补充资料：活塞行程
活塞行程：活塞运行在上下两个止点间(即上止点和下止点)的距离称为活塞行程。它等于曲轴旋转半径长度的两倍。
