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(yīng)用麥克斯韋方程推導(dǎo)出了各向異性晶體中點(diǎn)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(jí)子波面應(yīng)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(shí)際中線面重構(gòu)的局限性問(wèn)題,運(yùn)用UG軟件的線面造型、分析、計(jì)算、查詢等功能,通過(guò)UG軟件的開(kāi)發(fā)工具,直接調(diào)用UG軟件內(nèi)部函數(shù),編寫了“原始曲線”、“基準(zhǔn)平面”和“求取交點(diǎn)”3個(gè)程序,快捷簡(jiǎn)便地生成新的插值點(diǎn),從而進(jìn)行線面重構(gòu)。
