摘要
根据斯托克斯定律和牛顿第二定律导出了小球到达终极速度前 ,小球的运动距离与速度之间的函数关系 ,从理论上对计时起点的确定给予了证明 。
Basing on Stokes'law and Newton's second law,the function of moving distance of spherule with velocity is deduced before the velocity of spherule comes to the terminal velocity.Using this result,the starting time is determined,and the rational size of spherule is discussed.
