The advantage of the simulation system is as following : by adjusting the experiment ' s parameters arbitrarily , the distribution of light intensity and the design of fraunhofer diffraction can be observed and analyzed
仿真实验的特点是：通过改变可调参数，得到相应的实验现象，方便于分析各种衍射屏的衍射特点。
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 . the structure design of this device and micro - machined technique are also discussed
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。
