This paper discusses the ray surface and the wave normal surface of a spot light source in anisotropism crystal by means of Maxwell's equation, and presents the secondary wave surface used in determining directions of extraordinary rays and obtains that waves in crystals by Huygens' construction is ray surface rather than wave normal surface.

應用麥克斯韋方程推導出了各向異性晶體中點光源的光線面和波法面 ,闡述了用惠更斯作圖法確定晶體中非常光光線方向和波方向所采用的次級子波面應是光線面而不是波法

The new interpolated points are created quickly by using the programs to realize reconstruction of curves and surfaces.

分析了工程實際中線面重構的局限性問題,運用UG軟件的線面造型、分析、計算、查詢等功能,通過UG軟件的開發工具,直接調用UG軟件內部函數,編寫了“原始曲線”、“基準平面”和“求取交點”3個程序,快捷簡便地生成新的插值點,從而進行線面重構。
