By the scattering factor of henke , we calculated the peak reflectence of all possible material pairs from the recurve method of thin film optics . from the calculating results , the best material pairs of the five wavelengths are determined 从薄膜光学理论的递推法出发，以henke的散射因子为依据，计算了候选材料的峰值反射率，从中得到了软x射线短波段的五个波长处的最佳材料配对。
