摘　　要：以单靶核Rutherford散射的计算机模拟程序为基础,编写了多靶核Rutherford散射的模拟程序。应用多靶核模拟程序直观地研究了多次散射、靶核遮掩、电子屏蔽等影响Rutherford散射公式适用性的因素,更好地理解和分析了小角度Rutherford散射的物理图像,并通过对不同因素的对比分析,找出了影响小角度Rutherford散射的主要因素。Based on the computer simulation program of the single target Rutherford scattering,a simulation program of multiple target Rutherford scattering is compiled. The factors that affect the applicability of the Rutherford scattering formula such as multiple scattering,target nucleus covering,electron shielding,etc.,are intuitively studied by using the multiple target simulation program. The physical images of the small angle Rutherford scattering can be understood and analyzed better. By comparing and analyzing the different factors,the main factors that influence the small angle Rutherford scattering are found.
