摘　　要：本文阐明了在输矿皮带上进行γ能谱试验的目的、原理、试验装置及测试方法。由于采用铀、氡含量与它们的高低两个γ谱段的二元线性回归分析方法求得仪器转换系数,不仅快速给出有效平衡系数,而且也解决了在铀、镭不平衡状态下直接测铀的重大难题。In this paper the test principle, test set and surveying methods for conducting gammas-ray spectrometry on conveyer are presented. The conversion coefficient of the spectrometer has been found by using dual linar regression analysis of uranium and radon and their higher and lower bands of gamma-ray spectra. The efficient equilibrium factor can be quickly determined, and the direct determination of uranium in the non-equilibrium condition of uranium and radium can be made
