The catalysts with Rh loading on different cerium-zirconium mixed oxides were characterized by BET, H2-TPR and OSC. The effects of different cerium-zirconium mixed oxides on catalytic performance and thermal stability of Rh loaded catalyst were studied. The results show that: (1) Rh can enhance cerium-zirconium mixed oxides OSC and catalytic reaction rates; (2) cerium-zirconium mixed oxides with high Ce contents and low Zr contents are more favorable to the stability of catalysts. Moreover, the contents of CeO2 have important effect on catalysts characteristics, and the addition of some rare earth components, such as La, Pr and Nd also have some influences.

不锈钢的温度域被实验和一个有限元素(FE ) 模型在成双转动的长带扔期间模仿。由把测量结果与模仿的价值作比较，他们适合结束到对方，这被发现，它显示这个 FE 模型是有效的。基于这个模型，团结上的转动差距(t) 和转动半径(R) 的效果被模仿。模仿的结果给在 t 或 R 和结冰的点的位置之间的关系。更大 t 是并且 R 越小，结冰的点的位置是越多 closer 到出口。
