在消化和解剖国外表面型核水分/密度计的基础上,按照透射法和背向散射法测量密度的原理以及最大测量深度为500mm,设计了实验测量装置和实验样机。经实验确定了放射源、探测器、最佳几何响应、率定系统、数字模型、计算程序、测量线路和微
On the basis of digestion and dissection of the foreign surface nuclear moisture / density meter, the principle of measuring the density by the transmission method and the backscattering method and the maximum measuring depth of 500 mm, the experimental measuring device and the experimental prototype were designed. The experiment confirmed the radioactive sources, detectors, the best geometric response, rate setting system, digital model, calculation procedures, measurement lines and micro
