两类可展面的展开方法均被应用于工程实际问题。

It is proven that the choice of entrance of light and the beginning of the tangent from crystal surface has no effect on resolving the final direction of light in crystal by Huygensdiagraph and a conclusion that light will still spread in line in singleaxiscrystal is drawn.

当光波入射至单轴晶体时，由于晶体结构的各向异性，入射光波在晶体中将分成两束，一束称o光或称寻常光，另一束称e光或非寻常光，这种现象被称为双折射。对于o光和

The hemispherical spectral reflectivity of the surface of a strip tangent to an integrating sphere is determined by a high-speed lock-in technique. At the same time, the radiance temperature of the strip is measured by the multi-wavelength high-speed pyrometer from approximately 1000 K to the melting point.

带状试样被亚秒级的脉冲大电流通电加热到溶点，其表面的光谱半球反射比利用高速的数字锁相技术可方便地获得，同时一台多波长高速高温计可测量被测试样从1000K到溶点的光谱温度。
