力矩器是力平衡加速度表的关键组件。

The moment device is a key part of a force-balance accelerometer.

在列车低速运行时，这种速度感比从速度表上读数更具直接性。

While a locomotive runs at a low speed, this sense is more directly perceived than that from reading the speedometer.

车厢里的电子速度表已经达到231公里/小时，我对面的日本商人从笔记本上抬起头来，赞许的点了点头。

When the digital speedometer in the car hits 231 km/h, the Japanese businessmen sitting across from me look up from their laptops and nod in approval.
