摘　　要：采用蒙特卡罗SRIM程序模拟具有1ke V^14 Me V能量的质子在核-4乳胶中运动的能量沉积,将质子相对核乳胶面的入射角度分成了斜入射(最大角为30°)和正入射两类进行了讨论,同时采用最小二乘拟合方法导出了正入射时质子的射程-能量解析关系式,其误差小于1%.这些结论对一些实验的准备和数据处理具有一定的指导价值.The range-energy relation of a proton when impacting on the N-4 nuclear emulsion plane were in-vestigated using classical SRIM Monte Carlo program and curve fitting method,covering the incident proton en-ergy range from 0.001 to 14 MeV and the incident angle range of 0°~30°.A definite analytic expression was de-rived from this simulation with the errors below 1%.The results have extraordinary significance for the prepar-ing and prediction of some experiments.
