过热的弹簧应该更换，因为失去弹性的弹簧运行时达不到满意的效果。可使用弹簧弹力计进行检测。

Overheated springs should be replaced, since they may have lost tension and will not operate satisfactorily. Spring pressure can be tested with a spring-tension tester.

如果你喜欢床架，这有两种款式——不仅仅是弹力感觉的弹簧板条和更坚实的平板板条。

Should you prefer a bedstead, there are two types – a sprung slat that gives more of a spring, and a solid slat that has a firmer feel.

But if I'm accelerating, the force exerted by the spring and therefore, the needle the weighing machine reads is m.

但是如果我在加速运动,那么弹簧的弹力,也就是称重机上指针的读数就是 m
