Therefore we could carry out numerical calculations and obtain the reaction cross section , the nucleon removal cross section and the momentum distribution in the scattering of a halo nucleus with any types of density distributions . we compare the reaction cross sections calculated in the few - body glauber theory and the optical - limit glauber theory 进一步对27p 、 28p反应截面的研究分析表明，考虑核芯2751的增大可以很好解释实验测量得到28p反应截面的增大，而要解释27p反应截面的异常增大，需要同时考虑核芯2 “ si增大和具有非常弥散空间分布的2s ， ， :态晕核子。
By changing some parameters of the original model , such as the location and stiffness of the link members , the location of the transfer - story , the stiffness of the girders on transfer - story , the stiffness of core - tube , the area of the removed slabs and so on , this paper studies the influence of these parameters on seismic behaviour and dynamic characteristics and the seismic behaviours of this building and gives the reasonable proposals on the design of the structure 在上述研究的基础上，改变原型结构的有关参数，如连接构件的位置及刚度、转换层的西安建筑科技大学博士学位论文位置、转换大梁的刚度、核芯筒的刚度、楼板开洞的大小等，分析了上述参数变化对结构的动力特性和抗震性能的影响，并对此类结构的设计提出了合理化建议。
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 为使理论计算变得可行，我们在核芯和靶核密度采用多个高斯分布拟合的情况下，解析求解了各个散射矩阵元中的光学相移函数及交叉项含有的与晕核核芯、靶核密度分布有关的积分;同时对与碰撞参数和晕核子坐标有关的积分(八重以上，并且积分维数随晕核子数很快增加)采用蒙特卡洛方法计算。
