摘　　要：以将航空γ能谱低能谱段(≤600keV)信息开发应用于地质勘查工作为目的,通过蒙特卡罗方法和γ能谱测量实验对Al、Fe、大理石、混凝土等不同材料上形成的γ能谱低能谱段规律进行了系统研究,确定了γ射线低能谱段形状特征与吸收材料(平均)原子序数、密度之间的关联规律。为利用航空γ能谱低能谱段信息解决地质物性参数和岩性确认提供了依据。It studies the low-energy spectrum of γ spectrum（≤600keV） in aviation and its application in geological survey. On the basis of the Monte Carlo methods and a systemic study on the law of y Spec-trum low-energy spectrum and y-ray spectrometry experiments on Al. Fe.marble. concrete materials etc, discovers the relations between the characteristics of shape and the effective atomic number and the density of the material. This provides the evidence for the use of the low-energy spectrum of 7 spectrum in aviation to solve the confirmation on the geological parameters and petrology.
