rotational speed

基本解释

This system can complete the engine rotational speed and torque high accuracy control and the test, also engine temperature, pressure, oil consumption parameters survey.
本系统能够完成发动机的转速、转矩的高精度控制与测试，以及发动机温度、压力、油耗等指标参数的测量。
One important challenge with storage technology to note is that while storage capabilities of disk are increasing dramatically, the rotational speed of the disk increases at a much slower pace.
关于存储技术需要注意的一项重要挑战是，尽管磁盘存储功能得到了极大的改进，但是磁盘的旋转速度却没有太大的提高。
Unlike the better balanced straight-six or even the ultra-smooth V-12 engine, the humble four-cylinder generates an up and down vibration with a frequency of twice the crankshaft's rotational speed.
不像运行起来比它更稳定的直列六缸引擎或者极其流畅的V-12引擎，卑微的四缸引擎会以一种比自身机轴转速高两倍的频率产生一上一下的振动。

With little inertia, friction or drag, the wheel can be spun up to speed in a trice, and then made to dump its rotational energy back into the car's transmission in seconds.

The rolling of reel along eccentricity rail results irregular motion when mechanism work. The force of inertia will increase with the rotational speed of reel.
全喂入联合收割机的拨禾轮是一偏心曲柄滑道机构,工作时支承滚轮沿偏心滑道做不规则运动,当拨禾轮的转速较高时必然产生惯性力,机构惯性力引起拨禾轮振动,引起零部件损坏和联合收割机的割前损失。
