活动件 meaning in English
moving parts
Examples
- Lash and secure all the movable equipment
固定各种活动件。 - The total kinetic resistance of a moving part ( a firearm bolt ) was acquired by experiment because water resistance was difficult to be got accurately
因水阻力较难准确求得，可利用实验确定活动件（枪机）运动总阻力。 - Connectors for electronic equipment - part 4 - 107 : printed board connectors with assessed quality ; detail specification for shielded two - part connectors having a basic grid of 2 , 0 mm , fixed part with solder and press - in terminations for printed boards , free part with non - accessible insulation displacement and crimp terminations
电子设备用连接器.第4 - 107部分:经质量评定的印制板连接器.基本网格为2 . 0mm有屏蔽的两件式连接器详细规范,固定件带有焊接和压入接端,活动件带有不可接触的隔离位移和压接接端 - The method is described as follows : the velocity of the moving part and the gas chamber pressure were measured with a dynamic test measurement system ; a dynamic model was built on force analysis of the moving part ; the total kinetic resistance replaced the horizontal friction and water resistance ; then the resistance - velocity relation curves at moving stages were obtained ; with the empirical formula of the gas chamber pressure and the resistance - velocity relation curves , the preliminary dynamic characteristics were analyzed and the structural form and key parameters of an underwater assault rifle were determined
具体方法为：由动力学测量系统测得活动件速度和气室压力；分析活动件的受力，建立动力学模型；以运动总阻力代替水平方向上的摩擦阻力和水阻力，获得各运动阶段的阻力速度关系曲线；利用气室压力经验公式和阻力速度关系曲线，对水下突击步枪进行初步的动力学分析，确定其构造型式及主要参数。
