求翻译：只要将轴承放置在温度为100℃的电热板上几分钟即可，此法最为简单方便，如果翻转几次就可使轴承受热均匀，而且效率也较高，无论大小轴承都可使用此法来加热。是什么意思？

As long as the bearings are placed on electric heating plate in the temperature of 100 ° c for a few minutes, this method is most convenient, if you flip a few times to make bearings heat evenly, and the efficiency is high, regardless of size, bearing this method can be used both to heat.
