用多元线性回归法计算铀矿样中的U、Ra、Th和K含量

Calculation of U, Ra, Th and K contents in uranium ore by multiple linear regression method

我们用多元线性回归方法计算铀矿样的γ能谱,从而确定了U、Ra、Th和K的含量。和逆矩阵相比,其优点是不需要用纯U、Ra、Th和K标准样来求解响应系数。

A multiple linear regression method was used to compute γ spectra of uranium ore samples and to calculate contents of U, Ra, Th, and K. In comparison with the inverse matrix method, its advantagelies is in the fact that no standard samples of pure U, Ra, Th and K are needed for obtaining reaponse coefficients.
