动力学这个词,除了意味着力学而外,还有与静力学相对的意思。至于静力学与动力学有什么不同,简单地说恐怕就是关于惯性的问题吧。表示惯性的物理量是质量,而在动力学中,必须把质量m和重量W区别开来。 本讲是关于滑道和料道的动力学。理论不是一切,但以理论为基础这一点是不能忘记的。如果能在设计和故障分析中能得到应用,将甚感荣幸。 The term dynamics, in addition to mechanics, also has the meaning of statics. As for the statics and dynamics are different, simply say I am afraid that is the issue of inertia. The physical quantity that represents inertia is mass, and in dynamics, mass m and weight W must be distinguished. This talk is about the dynamics of skids and runners. Theory is not everything, but this can not be forgotten on the basis of theory. It would be a great honor if it could be applied in design and fault analysis.
