摘　　要：采用直接动力学方法研究了CF3CHFCF3与氯原子反应的动力学特性,利用包含小曲率隧道效应的正则变分过渡态理论确定了200~2000 K温度区间内反应的速率常数.The kinetic properties of the hydrogen abstraction reaction of CF3CHFCF3 and Cl,generating CF3CFCF3 plus HCl,were investigated using direct kinetics method.The rate constants for the reaction over a wide temperature range of 200-2 000 K were determined by making use of canonical variational transition state theory（CVT） involving small-curvature tunneling correction（SCT）.
