Hong博士没有透露他使用的是那种化学物质，但这种机器人的移动速度的确惊人，它也能像“化学机器人”一样挤过小于自身原始直径的小孔。

Dr Hong will not yet say which chemicals he USES, but the robot moves impressively fast. It can also, like the Chembot, squeeze through openings smaller than its initial diameter.

圆筒是基本的圆沿着直线移动的轨迹，可以考虑为相同直径的圆的集合，如果水平放置节片的话它就是直线。

Circular cylinder is a basic move along a straight line trajectory can be considered as a collection of the same diameter of the circle, if the horizontal section of film, then it is a straight line.

粒子直径越大、密度越大、转速越高，在同样时间内，粒子移动的距离越远。

The bigger the particle diameter, the higher the particle density, and the faster the rotation speed of mold, then the longer the distance of particle movement will be.
