加速度定义
So, the definition will take effect. The acceleration is as a vector, and the acceleration vector is just the derivative of a velocity vector.───有必要对加速度给出一个严格的定义，加速度,作为一个矢量,是速度的一阶导数。
briefly derivate a general acceleration formula of curvilinear motion with an acceleration definition and the concepts of curvature circle, and obtains an important conclusion.───加速度的定义和曲率圆的概念较简单地推导出了一些曲线运动中加速度的公式，并得出一些重要结论。
From the definition for the magnetic acceleration, the ideal magnetic field model and the magnetic field intensity profile needed for creating the micro-gravity environment are presented.───由磁加速度的定义出发，提出了理想磁场模型和实现微重力环境所要求的磁场强度分布。
