在微正则过渡态理论（μTST）和微正则变分过渡态理论（μVT）的基础上,构造了一种量子变分RRKM速率常数的新算法,用于计算化学反应的k（E,J）,k（E）和k（T）.该算法包括了Beyer-Swinehart的隧道校准方法的微正则速率常数的计算.在该方法中发展了一种截断式内插法,可有效的计算热速率常数中的Boltzmann积分.通过对H（D）2CO→H（D）2+CO,CH2CO→CH2+CO和CH4+H→CH3+H2反应的检验可看出,其计算结果与采用更精确计算方法的结果相当符合,但本方法可节省大量机时. Based on the theory of μTST and μVT, a new algorithm for calculating the rate constants of quantum variable RRKM is proposed to calculate the k (E, J) , k (E) and k (T). The algorithm includes the calculation of the micro-regular rate constant of the Beyer-Swinehart tunneling method. In this method, a truncated interpolation method is developed that efficiently calculates the thermal velocity The Boltzmann integral in the constant can be seen by checking the reaction of H (D) 2CO → H (D) 2 + CO, CH2CO → CH2 + CO and CH4 + H → CH3 + H2. The results of the method are quite consistent, but this method can save a lot of time.
