| 摘 要： | 从理论上对归一化总梯度法在充电法中的应用进行了基础研究,并用归一化总梯度法对直接充电的模型实验结果、近矿围岩(间接)充电的理论计算结果和野外实际观测结果进行了解释。结果表明,根据归一化总梯度垂直断面图和不同深度的平面图可较好地确定异常体的中心深度并大致确定其它一些几何参数,为进一步电性参数反演提供较好的初始剖面。

| Abstract: | In the light of characteristics of analytic continuation and odd points of the potential field function, the authors, using the principle of normalization, deduced the normalized total grads method, and conducted a basic theoretical study on the application of this method to "mise-a-la-masse" technique. In addition, the normalized total grads method was used to interprete the model experimental result of direct charge, the theoretical computational result of indirect charge of near-ore wallrock, and the field observational result. It is proved that the normalized total grads vertical sections and the plans at different depths can be employed to determine central depths of anomalous bodies quite satisfactorily and to define roughly some other geometric parameters. Hence, the fairly good initial profile can be provided for further inversion of electrical parameters. |
