摘　　要：针对钾盐矿床的探测和定位,利用TMS320LF2407内嵌的ADC及相应的幅度分析器完成多道伽马能谱测量,通过有效的稳谱和寻峰达到对HK-2钾盐能谱的精确测量,并利用谱线平滑技术对HK-2钾盐的能谱进行处理以满足系统检测要求。通过测试本系统能量分辨率可达7.8%,稳定性在一倍方差内计数可达到73.3%,两倍和三倍方差内计数都能达到100%。在矿物质同位素分析及合金成像系统的应用中,取得了满意的效果。For the detection and positioning of potassium salt deposits, it accomplished muti-channel γ spectrometry measurement using ADC that was embedded in TMS320LF2407 and the corresponding nuclear pulse range system, and achieved the precise measurement of HK-2 potassium salt by effective amplitude stabling and search peak, it also disposaled the spectrometry of HK-2 potassium salt with the technology of spectral line smoothness to fulfil the requirement for system detection. Its energy resolution was up to 7. 8%, and double the variance in the count can be achieved to 73.3, twice and three times the variance within the count to achieve 100M when was tested, It obtained satisfactory results in isotope analysis with minerals and the application of alloy imaging system.
