According to the boundary relations of the electromagnetic field, and based on the phenomena of double refraction and double reflection in crystals, the reflectivity and transmissivity are deduced at boundary when an extraordinary beam is incident from an isotropic medium upon a crystal or from a crystal to an isotropic medium with optical ax.

为分析非常偏振光在晶体表面的能量损耗，给出一种求解反射率和透射率的方法，即根据电磁场的边值关系以及晶体的双折射和双反射现象，求解晶体光轴在入射面内时，非常偏振光从各向同性介质入射到晶体和从晶体出射到各向同性介质两种情况的反射率和透射率的方法，并给出反射率和透射率的解析解，同时得到对于晶体光轴在入射面内的情况，光轴的取向对非常偏振光反射率的大小几乎没有影响，但对产生全反射的临界角θc影响较大的结论。

Taking the stem from three varieties of Dracaena fragrans as a material, the effect of the factors such as the plant growth regulators, the different basal culture medium, silver nitrate, and the cultivation medium upon tissue culture regeneration were investigated.

以3个也门铁品种（金心也门铁、金边也门铁和普通也门铁）茎段为材料，研究了植物生长调节物质、基本培养种类、AgNO3、栽培基质等因素对其离体再生的影响。

The apical buds and axillary buds of Dracaena cambodiana Pierre ex Gagnep. were inoculated on MS medium containing 1 mg/L BA, 0.1 mg/L NAA, 100 mg/L PVP and 30 g/L sucrose for inducing shoots. After cultured for 40~50 d, the shoots bourgeoned. They were then transferred onto MS medium supplemented with 2 mg/L BA, 0.5 mg/L KT and 30 g/L sucrose for inducing clustered buds. After 25~10 d, the clustered buds formed. The proliferation rate of the clustered buds was 300%~500% per month.
