摘要
利用射线光学理论和等效球Ｍｉｃ理论，计算了卷云中六棱状冰晶和六角片状冰晶及两种假设冰晶谱的单次散射参数，并对两种计算结果进行了详细分析和比较、得到一些有用的结论。
In this peper single scattering parameters of two types uf cn，stals（lculunlnar and hexa8onal plate-like crystals）and hypothetical crystal size spoctra are calculated by the schenies based on Mie theoryand ray opties,respectively，The results are closely analysed and compared，thus some usefulconclusions are obtained.
