The low speed machine usually has a short and fat structure in order to use effectively the rotating speed of the rotor, as contrasted with the long and thin structure of the high speed machine.

由于电机转速很低，为了充分利用其圆周线速度，一般需要采用直径大而轴向长度短的结构，与传统高速电机的细长结构有很大区别。

Early computer's computational speed low and the prevailing scientific computing and data processing is not affected, but can not meet the requirements of real-time control machine.

早期计算机的运算速度低，对当时的科学计算和数据处理影响还不大，但不能适应机床实时控制的要求。

Excellent antifriction capability, can make the machine in low speed vibration or discontinuous sliding reduced to the minimum.

优良的减摩性能，可使机床在低速下将振动或间断滑动减为最小。

Both the vehicle's manufacturers and the helpful folks at Triangle Segway, a dealer in Raleigh that loaned me the machine, had warned against straying from low-speed roads and sidewalks.
