例句與造句

1. In order to make the theoretical calculation feasible , we first obtain an analytical formalism of partial integrals with respect to the coordinates of the core and target in the phase - shift functions and their cross terms of scattering matrix elements , if the density distributions of the core and target are fitted to a few gaussian forms . then the rest multidimensional integrals with respect to the impact parameter and coordinates of halo nucleons are performed by a monte carlo method
   為使理論計算變得可行，我們在核芯和靶核密度采用多個高斯分布擬合的情況下，解析求解了各個散射矩陣元中的光學(xué)相移函數(shù)及交叉項含有的與暈核核芯、靶核密度分布有關(guān)的積分;同時對與碰撞參數(shù)和暈核子坐標(biāo)有關(guān)的積分(八重以上，并且積分維數(shù)隨暈核子數(shù)很快增加)采用蒙特卡洛方法計算。
2. It's difficult to find multidimensional integrals in a sentence. 用multidimensional integrals造句挺難的
