P_R
- 此为地球物理中的，正演模型 根据首播，和一些参数设定来求解 正演曲线，单位简单模型，不考虑衍射-this as geophysics, his model is based on a transcr ipt, and some of the parameters are set to solve his curve, units simple model without considering the diffraction
光子晶体带边附近的大色散效应
- We have used phase-sensitive ultrashort-pulse interferometry to study the modifi cation of optical pulse propagation near the photonic band edges in colloidal crystals consisting of polystyrene spheres in water. A strong suppression of the group
ZEMAX
- ZEMAX是美国Focus Software Inc.所发展出的光学设计软件，可做光学组件设计与照明系统的照度分析，也可建立反射，折射，绕射等光学模型，并结合优化，公差等分析功能，是套可以运算Seqential及Non-Seqential的软件。 -ZEMAX U.S. Focus Software Inc. The development of optical design software, optical components can do the illumination design
On-the-residentiall
- 我国目前对噪音污染的治理方法主要有两种：一种是将水泥路 面的改柏油路面第二种是在距离住宅窗户较近的道路两侧安装隔音 屏障。但效果均不理想。路面改变只可降低汽车行驶摩擦声的3～5 分贝左右。至于安装隔音屏障．由于声波的衍射特性，声音的传播可 以跨越隔音屏障，在中频，高频声波传播中，遇到难以穿透的障碍物 时，背面就有一个声波微弱的影区。所以此举只对相近楼层有所缓 解，对更高楼层的住户而言，效果并不明显-Our current treatment methods for noi
