分波分析 meaning in English
partial wave analysis
Examples
- To avoid depending on special physical model and find out a universal result , one can only uses dynamical analysis to get fitting formula . pwa is just a succinct and available method that does n ' t depend on special model
为了尽量少依赖于特定的物理模型，以使分析的结果具有普遍的意义，人们通过粒子运动学分析给出截面的拟合公式，分波分析就是这样一种不依赖于具体模型分析实验数据的有效方法。 - There are two types of pwa method , the non - relativistic paw method and the relativistic paw method which developed from 40 ' s and 50 ' s of twenty century ( including covariant tensor pwa method and helicities amplitude analysis method ) . the relativistic covariant full amplitude pwa method is a common way to search for new states in current
本文讨论的相对论协变全张量振幅分波分析方法是当前分析实验寻找新粒子态的一种常用方法，它充分利用了计算机的优势对所有实验信息进行拟合，是分析级联两体反应的一种简单而有效的方法。 - It takes advantages of modern computer to fit all the experimental information , hence a very powerful pwa method . in this thesis , we use this method to analysis hadrons japdecay model jap - > ( ptt - tr + and j p radioactive decay model based on the pwa amplitude , we received mass distribution of two outgoing pious and angle distribution of the outgoing particles using the cern program . finally we compared tow different form factors ( barrier factors and gauss factor ) wh ich were always used the calculating of pwa amplitude
本文采用这种分析方法给出的j强衰变j ~ - ~ +和j粒子辐射衰变j ~ - ~ +分波振幅公式，利用cern的蒙特卡罗模拟程序绘出了末态粒子的角分布和不变质量分布，对分波分析中常用的两种动力学形状因子(中心位垒因子和高斯压低因子)进行了研究比较。 - The fourth chapter lists out partial amplitude of using the pwa method described in chapter four , then we use cern programs to calculate out and plot angular distributions and mass distribution , finally we compare the influence of different form factors . the fifth chapter adopts the same process of the third chapter to analysis the decay the last chapter summaries our work and prospects further studying fields based on this thesis
第四章利用第三章描述的方法对j ~ - ~ +衰变进行了分波分析，然后用cern程序库中的蒙特卡罗模拟程序和paw软件对各个分波振幅进行了数值计算和绘图，在给出各种分波成分末态粒子不变质量分布和角分布的基础上，分析了两种形状因子对不变质量分布的影响。
