实验证明，该系统能够较好地测定感应电动机的转矩-转速特性。
Experimental result shows that the system can measure well torque-speed characteristic of induction motor.
由于这是一种非破坏试验方法，所以仅一个模型就可以对几种不同转速以及静过盈状态下的应力进行测定。
The test method employed is non-destructive, so that only one model is needed for investigating stresses in a rotating disc at various speeds, and for determining the static shrink fit stresses.
