通过对固体颗粒的运动和受力分析发现固体颗粒在沉降过程中径向合力几乎处处为零，不存在所谓的径向合力为零的一个平衡轨迹面，但存在着一个径向沉降速度为零的轨迹面，这一轨迹面就是平衡轨迹面法所要寻找的；首次推导出了该轨迹面半径与固体颗粒直径、水力旋流器自身几何参数以及操作参数之间的定量表达式。

When I painted the Narrative and Life Goes On as Usual series between 2004 and 2008, I created a great many fluid traces on these paintings by applying large amounts of low chroma oil paint, then juxtaposed different moments of life on the same picture plane by simultaneously using daubs of paint and scraping techniques. This in turn produced a backlight silhouette effect, imparting a sense of alienation and instability. These works primarily focus on exploring how images influence the life of the younger generation, and seek to achieve a visual balance between photography and painting.
