摘　　要：航空伽马全谱分析方法是基于全能谱数据进行的一种数据处理方法,实现过程除常规处理之外,还需大量的矩阵计算,通常用某一种编程语言调用MATLAB、SCILAB等科学计算工具才能实现,编程过程复杂且数据处理效率较低。作者基于Python和其丰富的第三方类库编程,用简短的程序编码实现了航空伽马射线全能谱分析方法的全过程,解决了只能通过调用其他数值计算软件来计算大矩阵、编程复杂且数据处理效率不高的问题。通过在云南昆明-昆阳磷矿试验区的运用及研究表明,基于Python编程航空伽马全能谱分析方法可行、结果可靠,为航空伽马全能谱数据处理以及类似研究提供了一种借鉴,值得应用和推广。Airborne gamma-ray full spectrum analysis is a data processing method based on the full spectrum data.In addition to considerable conventional processing,the method also requires large matrix calculations.Usually,it is implemented by a certain programming language using scientific calculating tools such as MATLAB and SCILAB.The programming process is complex and the data processing is relatively slow.Based on Python and its rich third-party libraries,the author implemented the entire process with a short program code which solved the problem that large matrix processing can only be calculated by professional numerical computing software with complex programming process and relatively slow processing speed.Then the method was applied in the test area of the Kunming-Kunyang Phosphate Mine in Yunnan and the result showed that the Python programming method of airborne gamma-ray full spectrum analysis was feasible and reliable.This research provided a reference for the data processing of airborne gamma-ray full energy spectrum which is worth to be used more widely.
