By means of simulink of Matlab, it is known that the method that electric field is strengthened and two damp holes are turned on can lead to transfer ratio of force to be fallen during the phase of low frequency; on the other hand, the method that electric field is weakened and two damp holes are turned off can lead to transfer ratio of force to be fallen during the phase of high frequency.

通过Matlab仿真计算可知，振动物体在低频阶段，加大电场和开启两阻尼孔能使力传递率较低；而在高频时，关闭电场和阻尼孔，其力传递率较小。

铝阳极氧化膜的蚀孔形貌与蚀孔生长机理研究。

The research shows that, when fluidized gas is used only, it had little effect on the quantity of returning solids, and that the effect of loosed gas is significant. Horizontal opening has distinct effect on the circulating rate only when the loosed gas is larger; the appropriate horizontal opening is corresponding to the gases quantity. The combining of the arced gas distributor and the gases regulating could eliminate the fluidized dead zone in the U-valve effectively.

结果表明，单一流化风对循环量的影响较小，而松动风对循环量的调节幅度比较大；水平孔口开度只有在松动风量较大时对循环量的影响比较明显，而且合适的水平孔口开度与输送风量的大小相对应；利用圆弧形布风板和气量调节相结合可以很好地消除阀体内的流化&死区&。
