以不同的多极量子数和初态，我们用约化的线性熵研究CH（CH3）3的耦合CH伸缩和弯曲振动的动力学纠缠，结果表明：在多极量子数大于等于3时，态｜0，2N）的最大纠缠能在较短的时间内得到；态｜N，0）的纠缠振荡频率比态｜0，2N）的要小，而振荡的幅度要大．

英文摘要：

The dynamical entanglement for the coupled C-H stretch and bend vibrations in CH（CF3）3 is studied in terms of the reduced linear entropy for various polyads N and initial states. It is shown that for a given polyad N≥3, a maximum entanglement for state ｜0,2N） can be obtained with a shorter time, and the entanglement oscillatory frequency for state ｜N,0） is shorter than that for state ｜0,2N）, where the amplitude of the former state is larger than that of the later one.
