These switches are used to monitor liquid levels by opening or closing when a desired action point is reached. 此类开关用于侦测液面的高度,在达到所需运作范围后便开启或关闭。
Minute an action point, comment, etc 记录一行动要点、评语等
The influence of impulse duration, direction, and damage position, extent on the velocity wave at the impulse action point is addressed. 研究了脉冲持续时间和作用方向、损伤位置和程度对脉冲作用点(AP)速度波的影响规律。
It also discusses in detail the impact on vibration noise with different boundary, different load and different action point. 并详细讨论了不同边界、不同载荷、不同作用点(AP)对振动噪声的影响。
The relative positions of the action point of earth pressure on the wall were calculated after having found the dimension of active earth pressure and passive earth pressure, using the moment equilibrium of the sliding mass. 在确定了主动土压力和被动土压力的大小后,利用滑动体静力平衡的力矩平衡方程计算力的作用点(AP)在墙体的相对位置。
