摘　　要：利用量子效应原理分析了波包在势阱中的传输,通过分类讨论得出了出现共振透射现象的条件。将其与已有高功率微波孔缝耦合的数值模拟和实验结果相比较发现:其共振条件和使用数值模拟和实验得到的共振条件基本一致,即垂直入射电场分量的缝(或边)为入射半波长的整数倍时会出现共振增强现象。不仅验证了已有的高功率微波孔缝耦合数值模拟和实验结果,而且有助于解释一些复杂电子系统高功率微波效应实验中出现的强耦合现象。The transmission of wave packets in a potential well was analyzed by the quantum effect theory. The occurrence condition of resonant transmission was obtained by classified discussion. The comparison of it with results of the numerical simulation and coupling experiment shows a general agreement. That is, the resonant enhancement will take place if the slot side length is an integral multiple of the microwave half-wavelength, when the direction of the incident electric field is perpendicular to the long side of the slot. In the meantime, it would help to illuminate strong couplings in high power microwave effect experiments on complicated electronic systems.
