摘　　要：用箱式格式的有限差分法求解了电磁波在对流层中传播时所满足的抛物化波动方程。尤其利用该方法可以较为准确地计算出大气折射指数沿高度和距离方向变化时的电磁波衰落情况。文中也给出了该隐式格式的相容性、稳定性和收敛性的证明。An implicit finite-difference(IED) scheme is intreduced for solving the parabolic equationrepresenting electromagnetic wave propagation in the tropophere. Using Box methed, the fading of theelectromagnetic wave is calculated especially when the modified refractivity varies both with the range and theheight in the representative atmosphere conditio. The consistency ,stability and convergence of the Box method isdemonstrated.
