摘　　要：基于不同类型金矿床的能谱测据与金品位之间有不同的相关关系,对具体矿床单独建模预测是必要和可能的。能谱找金测据处理系统的设计就是根据测据处理的数学方法和步骤编制的。常用的多元线性回归分析预测效果往往不理想,而本系统对能谱测据作适当变换并计算权值、差值和有利度等预处理后,回归准确性显著提高。它同时可建立十多个数学模型,使用户有较大的选择余地。它采用树状程序结构,全中文菜单式提示,可逐级调用,也可单独运行各级子系统。它可移植于其它类似的地质矿床模型的测据(包括非能谱测据)处理。该系统快速、准确、简便、灵活,具有较大的实用性和推广价值。Based on different correlation between gamma-ray speetrometric data and gold grade in different types of gold deposits, it is necessary and possible to establish a mathematical model of gamma-ray spectrometric data processing for predicting specific gold deposits. A system design of gamma-ray spectrometric data processing for prospecting gold deposits has been worked out according to the mathematical method and procedure of data processing. The prediction effectiveness of commonly used multiple linear regression analysis is always not ideal but regression accuracy will be evidently increased after pre-processing of the calculated weight,deviation and favourability on gamma-ray spectrometric data. This system can establish more than ten models at the same time which enable users to have more choice. Tree structure and Chinese menu prompting are adopted in this system which can be utilized separately, sub-systems at different levels can be also individually operated. It can be transplanted to daal processing of other similar geological deposit models(including non-gamma ray spectrometric data). The system is rapid, accurate, simple, convenient and flexible in use, more practical and easily popularized.
