By changing the brush diameter, density, the gap between brush bristles and the axis, and the shape of brushedge, the influence of the structure parameters on the seal performance is obtained.
通过改变刷毛直径、刷毛密度、刷毛与轴的间隙以及刷毛齿形，分析了这些结构参数对密封性能的影响规律。

Line is simply a point that moves continuously, like the edge of a shape or the motion of a single brush stroke.
线就是点的连续移动，比如图形的边，或者画笔笔触的移动轨迹。
