摘　　要：重、磁异常的人机联作模拟反演(也称人机联作选择法),是根据选定地质模型及重、磁异常的正演计算公式,由给定的初始模型参数计算出理论场值,并与实际观测场值进行对比,根据对比中确定的不一致性或残差,依靠解释人员的经验来修改模型形状及物性参数,重新计算理论场值进行下一次对比,反复多次直至达到满意为止,人机联作选择法整体为一套计算机软件,并依据支撑条件的不同可分为在人机联作工作站上使用或在一般的微机上使用。人机联作选择法既可应用于二度体重、磁异常,也可以应用于三度体重、磁异常的模拟计算解释。Persons calculates magnetic and gravitational anomaly in computer(also calls interaction selection method)is according to designates the geological model and magnetic and gravitational to develop the formula,by the initial model parameter idea which assigns figures out the theory field value and carries on the contrast in the actual observation field value,according to contrasts the nonuniformity or the residual error which determineheavy,the magnetism unusual humancomputer interaction simulation inversion(also calls humancomputer interaction selection method),is according to designates the geological model and is heavy,the magnetism is unusual is developing the formula,by the initial model parameter idea which assigns figures out the theory field value,and carries on the contrast in the actual observation field value,according to contrasts the nonuniformity or the residual error which determines,depends upon explains personnel's experience revises the model shape and the natural parameter,the recomputation theory field value carries on the next contrast,repeatedly many times until achieves the satisfaction up to.The humam-computer interaction selection method whole is one set of computers software,and is different based on the strut condition may divide into uses on the humam- computer interaction workstation or uses on the common microcomputer. The humancomputer interaction selection method already may apply to 2D body weights,the magnetism exceptionally,also may be supposed to use in the 3D body weight,the magnetism unusual analog computation explanation is unusual to the 3D body.
