摘要
本文阐述了 NDH—A 型核子土基密度、含水量联合测定仪的测量原理、标定方法、使用试验及测试数据的分析.同时就中子源和γ源的相互干扰问题作了初步探讨.
This paper has described the measure principles,the calibration method,the application test and data analysis of the nuclear-earth-base-density-moisture-gauge of type NDH-A.And the interference brought about by neutron source and γ-source hasalso been discussed in it.
