particle movement

In this paper, a dynamic model for a single particle movement in impinging stream was developed. The formulas of particle residence time and movement track length in different flow type area was deduced and a count example was given.

建立了单一颗粒在对撞流中运动的动力学模型，推导了物料颗粒在不同流动状态中滞留时间及运动轨迹长度的计算公式，并给出计算实例，最终得出颗粒在对撞区中的运动情况。

There are two ways for the abrasive particle movement relative to material's surface: sliding and rolling.

磨料颗粒相对于材料表面的运动方向上主要可分解为两种运动方式, 即 滑动和滚动.

Basset force and virtual mass force are on the same magnitude as Stokes force and are important for the motion of abrasive particles during the initial phase of particle movement in the convergent section and straight tube section of the nozzle.

当磨料颗粒在喷嘴的收缩段和直柱段中运动时，磨料颗粒所受的Basset力、虚拟质量力与Stokes力处于同一量级，对磨料颗粒的运动影响很大，不可忽略；

we don't have sanitary towels, no. no? all right, not to worry. it's all right.

卫生巾我们没有没有没关系

The study of dynamic model of dust particle movement in coal face;

为此，开展农业物料颗粒运动规律的系统理论的研究尤为重要。

When the pollen tubes were treated with APM-a microtubule specific inhibitor, the cytoplasmic particle movement began to slow down and finally stopped.

用APM处理已萌发的花粉，还发现它能减缓花粉管中胞质颗粒运动的速度，甚至使运动停止。
