摘　　要：本文简要叙述了表面型核子水分-密度计的测量原理、结构形式、现场标定和校正方法,介绍了我国自行研制的FT—628型表面型核子水分-密度计在水利水电、筑路和建筑等工程进行质检的使用情况和现场对比测试。This paper describes the working principles, structure, field calibration and correction for the surface nuclear moisture-density gauge. It introduces the FT-628 gauge type developed in our country and its applications in the hydraulic and water power engineerings, road and building foundations to control the construction quality. The paper also presents the measuring comparison between the surface nuclear moisture-density gauge and the round knife sample method.
