This paper aims at designing a spectrum analyzing software,named Stone NaI,for digital measure instrument of building materials' native radioactivity,which is based on Windows operation system,utilizing Visual C~(++) and applied to be mate software of digital.It realizes three analyzing spectrum methods(Least-Square Method,Inverse Matrix Method and Least-Square Inverse Matrix Method) and their free switch,and being integrated of many function modules,such as data collection based on USB interface,data smoothing,peak search,energy calibration,spectrum zoom in and zoom out,logarithm nature displaying and dot line displaying etc.It also realizes two spectrum analyzing mode: manual analyzing mode and quick analyzing mode,and satisfies the different analyzing requests of different survey environments.
