摘　　要：采用不对称Eckart势垒，研究了甲硅硫醛单分子热解体系中的隧道效应．讨论了多种因素影响下的反应速率常数及相应的活化能及在考虑隧道效应条件下，势垒的不对称性对计算结果的影响，所得结果与甲硫醛结果做了比较．Using Asymmetrical Eckart potential energy barrier, we have investigated thermal reaction system of Silathione. Several factors influence on the reaction constants and corresponding activation energies were disscussed, as well as the influence of the asymmetry ofpotential on the results of calculations in the case of tunneling. In addition, we have compared those results with those results of Thioformaldehyde.

关 键 词：隧道效应 不对称Eckart势 甲硅硫醛热反应
