Based on the modified refractivity under the unstable,neutral,and near neutral stability conditions,the distribution of electromagnetic field under variant atmospheric stability was given by Fourier split-step method of parabolicequation approximation.
基于不稳定层结、中性层结、稳定层结的修正折射率剖面,利用抛物型方程的Fourier split-step算法得到了不同大气层结条件下中的空间场分布。
The applicability of Model A in Chinese sea areas has been studied by using the modified refractivity profiles and hydrometeorological data measured in the experiments during recent years.
利用近几年采集的我国海区的实测修正折射率剖面和气象水文数据,得出了A模型在我国海区的适用性结论。
Puting the negative revised refraction index value into the optic multilayer theory caculation,the theoretical diffraction curve is consistent with the experimental one.
对小角Ｘ射线衍射法测出的Ｃｏ／Ｓｉ多层膜的平均折射率修正值为负的原因作了进一步的分析，提出了修正的具有化合物层的多层膜结构模型，运用光学多层膜理论计算小角衍射强度时代入了负的折射率修正值δ，得到的理论计算曲线与实验曲线趋于一致。
