And therefore almost every mountaineer has with him or her a device which converts mechanical energy into electricity.
因此几乎所有登山者，都会携带一种，能把机械能转化为电的装置。The efficiency rating of a motor describes how much of the electricity consumed is converted to mechanical energy.
电动机的效率等级表明多少消耗的电量转化成机械能。The sum of the kinetic and potential energy of the body is called its total mechanical energy.
物体的动能和势能之和称为物体的总机械能。The mechanical energy can be changed back into electrical energy by means of a generator or dynamo.
利用发电机可以把机械能转变成电能。The mechanical energy can be changed back into electrical energy by means of a dynamotor .
利用发电机可以把机械能从新转变成电能。So, let the total energy be just the mechanical energy which depends on my initial conditions wherever I start.
因此，总能量就是，机械能，它取决于我从哪里，出发的初始动能。The mechanical energy can be changed back into electrical energy by means of a generator.
利用发电机可以把机械能再转变成电能。To understand how this works, it's best to look inside a shock absorber to see its structure and function.
为了了解机械能转化为热能，最好的方法就是到一个避震器的内部，看看它的结构和运作方式。An exclusive technology developed by TRIANGLE. Like the end pin of a cello, it evacuates mechanical energy to the ground.
TRIANGLE开发的独家技术，如大提琴的尾柱，彻底地排除了机械能。
