查询词典 aster ray

In the second chapter, during the study of compound x-ray refractive lenses, diffraction function of compound lens is derived in the light of refraction and absorption effect and the design theory of X-ray is deduced using diffraction theory in connection with the characteristic of X-ray band.

在第二章X射线聚焦组合透镜的研究中，针对X射线波段的特性，综合考虑折射和吸收效应得出组合透镜的衍射屏函数，利用衍射理论推导出X射线聚焦组合透镜的设计理论并进行结构设计与微细加工制作技术研究。

In this paper, two-point ray tracing is studied for three-dimensional arbitrary interface. from Fermat's principle, traveltime is expanded in the initial ray path according to one order Taylor's incompletion expansion. Then, the algorithm of total iterative ray tracing in three dimension is derived.

作者在文中对三维任意界面情况下的两点间射线追踪问题进行了研究，从Fermat原理出发，对射线路径上的旅行时，采用一阶Taylor不完全展开等办法，推出了三维情况下计算射线路径的整体迭代算法。
