由此，本文主要应用Bayes方法对以下几方面进行了探讨：首先，在复杂假设下，本文利用圆散布误差这一精度指标对落点散布鉴定问题进行研究，它比以往所用的纵、横向偏差精度指标更具现实意义；分析了此鉴定问题的决策临界区域；给出其Bayes风险的具体表达式，对用数值积分进行近似求解的方法进行了改进；在此基础上，通过极小化试验的风险确定最优试验数n，并讨论了决策中犯两类错误的概率，给出了验前信息的表示。

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&。

Observing through SEM and TEM, we could found that the diameter of zeolite particle is during 10~20nm, the diameter of straight chain diatomite is between 8μm and 20μm, and the diameter of discoid diatomite is between 15μm and 20μm. From the diagram of TGA and DGA, we could draw the conclusion that the adsorption capacity of diatomite could be increased by heating method under appropriate temperature. The results of FTIR analysis show that there are several libration between 1510 cm~(-1) and 1529 cm~(-1), and this result can sufficiently prove the adsorption of benzene hydrocarbons.
