摘　　要：对波动方程差分(WEFD)解法进行了研究,给出了电场的计算公式。将它应用于谐振腔Q值的分析,得到了与理论值吻合得很好的结果。In this paper, the wave equation finite difference method （WEFD） is analyzed in XYZ-system. Formulas for calculating electric field are given. The perturbation method based on WEFD is investigated, and its application to calculate the resonator cavity Q factor is presented also. The calculation values agree well with the theoretical values.
