Ball uniform

A small ball is making circular motion at the uniform velocity, the centripetal force has suddenly increased, it is proved that the small ball will generally make a spiral motion.

详细讨论了当向心力突然增大后，原来作匀速圆周运动的小球其运动轨迹的变化情况，证明了小球将作螺线运动。

And then, the algorithm of generating uniform distribution on a ball or sphere is given.

然后介绍球面及球体上均匀随机向量的生成算法.

The finished product is ball granule with uniform size. Its fluidity and solubility are good. The purity of product is high and its quality is good.

所得产品为球状颗粒，粒度均匀，流动性好，溶解性好，产品纯度高，质量好。

The results of the kinematics research of the ball mediums show that the ball mediums in the mill go mainly through three steps: uniform circumference motion, no friction motion on the surface of the guiding board and parabola motion.

超临速磨机的运动学分析研究结果表明，钢球介质在一个运动循环周期内主要经历了三个运动阶段，即匀速圆周运动阶段、钢球介质在导向板表面无摩擦运动阶段和抛物线运动阶段。
