放射性勘探工作中的反褶积分层解释法

本文简要地叙述了放射性矿层的饱和度关系式,反褶积分层解释法的原理,特征参数α（或）的现场测定方法。并将反褶积法的分层解释结果与逐次迭代法、逆矩阵法和平均含量法的解释结果作了对比。大量的对比结果（超过1500m矿层厚度）表明,反褶积分层解释法不仅可以查明矿层内铀、钍含量的变化形态,区分矿层群中各个矿层和夹层,而且具有分层清楚,计算方法简单,生产效率高（比其它分层解释法高20-30倍）,为今后放射性勘探工作的数字化和自动化创造了必要的条件。

THE QUANTITATIVE SUBDIVISION INTERPRETATIONMETHOD BY DECONVOLUTION TECHNIQUEIN RADIOACTIVE PROSPECTING

This paper describes the radioactive saturation relationships, the principles of subdivision interpretation method and the methods of determination of filter parameter α （or α） in the field. The subdivision interpretation results by deconvolution are compared with those obtained by progressive substitution method, inverse matrix method and the commonly used average concentration method. A lot of experimental results （more than 1500 m of ore zone thickness） under different environment of uranium deposits exhibit the evident advantages of the application with the inverse digital filters, especially under the present technical conditions in our country.
