motive power

The motive power of trains is usually steam or electricity.

火车的动力通常是蒸汽或电。

So we can calculate from the conclusion, as the important motive power, achievement goal and self-efficacy may exist a certain connection with metamemory monitoring and control.

由此可以推测，对个体有重要作用的动机力量成就标和自我效能，与元记忆监控之问可能存在着某种联系。
