【摘要】 采用带密度修正的热中子透射计测陶料水分.因热中子透射率T_n和γ射线透射率T_γ均为样品水分百分含量P和质量W的函数,因而通过实验标定确定关系式P（T_n,T_γ）和W（T_n,T_γ）.通过对陶料样品的实际考核,在实用范围内,质量测量误差 0.65g,水分测量误差0.43%（m/m）,能满足现场使用要求.更多还原

【Abstract】 The methodology for measuring moisture in the pottery material using a thermal neutron transmission gauge with the density compensation is reported. The functional relation P(Tn,Tr) and W(Tn, Tr) can be determined by the experimental calibration, for the transmissivity of thermal neutron Tn and γ-transmissivity Tr are all the function of the moisture percentage P and the mass W. Through practical examination on the pottery material, within the practical extent, the measured errors for the mass and the moisture are 0. 65 g and 0. 43%(m/m) respectively. The gauge has satisfied requirements of the use in the worksite.更多还原
