molecular collision meaning in English
分子碰撞
Examples
- The transfer has been effected by a multitude of molecular collision .
这种转移是通过大量的分子碰撞而实现的。 - We also experimentally observed the effect of sodium atom - molecular collisions and sodium atom - atom collisions on the line - shape and intensity of fluorescence spectra . in addition , the optically pumped infrared stimulated emission and energy transfer up - conversion process are observed in pr3 + : y2sio5 , and with the threshold energy , temperature dependence and divergence angle for the stimulated radiation are measured
此外还研究了掺杂在固体y _ 2sio _ 5中的pr ~ ( 3 + )的光泵红外受激辐射和能量转移上转换，分别测得了红外受激辐射的阈值能量和发散角，并拟合得出了能量转移速率。 - With the flowchart the program can be divided into six parts and it includes initial flow field , computation of molecular motion , boundary treatment , re - sort of molecular , sample and computation of molecular collision . several cases have been simulated to certify the correctness of the program . dsmc method is improved using method of characteristics to modify the boundary condition and gets the goal as expected
首先,编程实现了基本dsmc方法对二维流动的计算,给出了所用算法的原理、相关模型,并结合程序结构流程图,分别介绍了初始化流场、计算分子的运动、边界的处理、分子的排序、抽样计算分子的碰撞、流场参数采样统计各个功能模块在fsmm2d中的实现,并对该程序进行了算例校验。
