力是一切运动的根本原因，自然科学与工程技术离不开对力的精确测量，物理学中的许多基本原理就是在实现了力的精确测量之后才最后确立的。人们最先想到的办法，是用杠杆原理和弹性体的形变来测力，这种巧妙而简单的办法一直沿用到今天。把力转换成电信号的技术，是在电学和电 Force is the root cause of all movements. Natural sciences and engineering are inseparable from the precise measurement of force. Many of the basic principles of physics are finally established after the accurate measurement of force is achieved. One of the first things people think of is measuring force using the principle of leverage and the deformation of the elastomer. This clever and simple method has been used today. The technique of converting force into electrical signals is in electricity and electricity
