放射性仪表被测物料分布非线性测量误差研究

A STUDY ON THE MEASURING ERRORS DUE TO THE NONLINEAR DISTRIBUTION OF THE MEASURED MATERIAL ON THE RADIATION DEVICES

讨论了放射性仪表测量物料分布非线性变化时，仪表测量误差的计算方法。物料分布非线性采用几何数学模型描述，概括出各种分布的普遍规律对测量误差的影响，并提出了对物料“线性测度”、“非线性测度”定义的一个方案。

The calculating methods of measuring errors due to the nonlinear distribution of the measured material on the radiation measuring devices are discessed,and a new definition of the granularity of materials is put forward.
