forward angle meaning in English
前方位角
Examples
- Based on the revers kinetic intermediate energy heavy ion collision in which much more intermediate mass fragments are emitted towards forward angles , a sensitive observable on isospin effects in heavy ion collisions is investigated by means of using isospin dependent quantum molecular dynamics ( iqmd )
摘要在重离子碰撞过程中，基于重质量的弹核轰击轻质量靶核有大量中等质量碎片向前发射的逆运动学效应，利用同位旋相关的量子分子动力学观察和研究了重离子碰撞过程中同位旋效应的灵敏性。 - The study of the effect of the momentun distribution of target nucleons on the scdw calculation is performed , which shows that the larger nucleon momentum compenents affect the double differential cross sections at backward and forward angles , while smaller nucleon momentum compenents affect the cross sections near the qes angle
本文还分析了核子动量分布对scdw模型双微分截面计算的影响，发现大动量的核子成分的增加会导致截面计算值在大角度区域和极小角度区域的增大；小动量核子成分的减小会导致截面计算值在准弹性散射角附近的减小。 - The calculated double differential cross section of the new model is compared with experimental data and previous scdw calculations with single particle model . the calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi - elastic scattering ( qes ) angle . the agreement with experimental data is much improved
新模型的双微分截面计算结果与实验值以及以前采用单粒子壳层模型时的计算结果进行了比较，表明cdfm模型的引入对scdw模型的计算结果有较大的改进，使其在大角度和极小角度区域有所增大，在准弹性散射角附近有所减小，从而能更好地与实验值相符合。
