中文摘要：
利用Rydberg波包分析量子力学体系的动力学行为是研究经典力学和量子力学的对应关系的一个非常重要的方法．本文主要研究了在外电场作用下平面转子的Rydberg波包的演化和恢复结构．结果表明：在弱电场作用下，波包仍可周期性的坍塌和恢复，但在强电场作用下，平面转子的Rydberg波包演化结构则与谐振子的相符．
英文摘要：
The use of Rydberg wave packet analyzing the dynamics of quantum mechanical systems is a very important method for studying the relations between the classical mechanics and the quantum mechanics. The evolution and revival structure of the plane rotor＇ s Rydberg wave packet in an external electric field is studied mainly in the present paper. The results show that the wave packet might be collapsed or resumed periodically if the external electric field is very weak, but in the strong electric field, the evolution and revival structure of the plane rotor＇ s Rydberg wave packet are in correspondence with that of the harmonic oscillator.
