| 摘 要： | 本认为,象判定物体是否运动需要有参照物一样,判定物体运动快慢需要有“参照运动”并给出参照运动定义,然后以函数y=x^3 c为例,给出一个新的导数定义,并说明其物理意义是严格的“即时速度”,而不是传统的“瞬时速度”。以此为基础给出微分、积分新的定义及其物理意义。

| Abstract: | This article introduces that jubging the speed of an object movement needs "reference movement" , the same as judging if an object is moving needs"reference object , and gives the definition of reference movement. A new derivative definition is defined and its physics meaning is explained to be strict "Immediate Velocity" rather than normal "Instantaneous Velocity "by giving function y=x3 c for an example . and a new definition of differential calculus, integvral calculus and their meaning are given on the basis of this. |
