摘要
分别用无穷级数展开方法和数值积分计算中的高斯 拉盖尔求积法对高能重离子碰撞中能量密度和粒子密度数值进行计算 ,并对结果及级数展开中的高次项和一次项的大小进行了比较。结果表明 :高斯 拉盖尔方法可以作为一种实用的算法应用在高能重离子碰撞的计算中。
Energy density and particle density in high energy heavy-ion collisions are calculated with infinite series expansion method and Gauss-Laguerre formulas in numerical integration separately, and the results of these two methods are compared, the higher terms and linear terms in series expansion are also compared. The results show that Gauss-Laguerre formulas is a good method in calculations of high energy heavy-ion collisions.
