The reaction channels and the reaction products in the collisional reactions between two C60 molecules are found to be sensitively dependent on the relative orientation between the colliding *** detailed collision processes and the stable structures of the products are studied by using a molecular dynamics simulation method combined with a Langevin molecular dynamics *** defects of the reaction products are also analyzed.

This paper has improved Hickman's nonadiabatic collision model by substituting Hickman's constant velocity classical straight line trajectory approximation with the solution of motion equation mR=-dV(R)/dR, and has calculated the cross sections of ion-pair formation Cs+O2 -Cs++O2- with the improved nonadiabatic collision model (INCM). A comparison of our results with other theoretical and experimental results has been made.

为进一步分析压缩机舌簧阀运动失效机理,揭示油膜黏滞力对舌簧阀运动过程的影响,建立黏滞作用下排气阀运动的单自由度系统模型.该模型综合考虑了阀片工作过程中与限位器发生贴绕的运动特点,以及黏滞力对阀片运动的影响.采用四阶龙格-库塔法编制程序,在MATLAB环境下进行数值求解,并通过排气阀位移测量实验进行验证.结果表明,考虑黏滞作用的运动模型计算结果中有71. 9%的数据点落在10%误差带内.与不考虑黏滞作用的单质点模型相比,该模型可更加准确地描述排气阀的动态特性.最后,利用新模型分析了运动黏度和阀片刚度对舌簧排气阀开启时间和关闭过程的影响.该研究可为舌簧阀的可靠性设计及耐久性研究提供参考.
