TiO〓/K-M supported Ag/SiO〓 composite ceramic membrane tubes have been prepared and used as a membrane reactor for selective separation of C〓H〓 during the catalytic reaction process of CO〓 partially oxidating C〓H〓. By removing C〓H〓 produced in the catalytic reaction, thermodynamic balance of the reaction is upset and some side reactions from C〓H〓 are avoided, thus the conversion rate of C〓H〓 and the selectivity to C〓H〓 are effectively increased.

本研究设计、制备了硅藻土—莫来石陶瓷管负载的Ag/SiO〓复合膜，并将其应用于二氧化碳部分氧化乙烷催化反应过程中产物乙烯的选择性分离，有效地提高了催化反应的反应物乙烷转化率和产物乙烯选择性。

It can be proposed that the TS-1/H〓O〓 catalyzed opening ring reaction of propylene oxide was an heterogeneous catalytic reaction occurred on the active sites on the surface of the catalyst, not an homogeneous reaction catalyzed by H〓.

根据已知的实验结果可以推断，TS-1/H〓O〓催化的PO的开环反应是发生在催化剂表面活性位上的非均相催化反应过程，与H〓催化的均相反应不同。

Moderate noise (75、85dBA), didn't has significant effect on simple control and reaction task such as two-hand coordinate tracking, complex reaction time and persuit aiming. After sustained exposure of 1. 5h to noise with intensity of 85、95 dB , there was a tendency to decrease in light tracking performance of dual task (light tracking and oddball vedio-moter reaction) with a very large difference among subjects. The attention distribution between main task and second task changed.

中等强度的噪声（75、85dBA），对于双手协调光标追踪、复杂反应时及目标跟踪等较为简单的操纵和反应并无显著影响；85、95dB强度的噪声持续暴露1.5h，可使双重任务（光标追踪和oddball视觉-运动反应）的光标追踪绩效有降低的趋势，并有很大的个体差异，主、次任务之间的注意分配发生了改变。
