| 摘 要： | 海洋重磁资料的平差处理是海洋重磁资料处理过程中必不可少的环节之一。从最小二乘算法意义下的平差处理基本理论出发，建立起平羞测线网系统交点误差的方程组，给出了方程组系数矩阵的简单求取方法。理论计算和实际资料处理结果表明，该方法不仅原理简单，计算机实现方便，而且经平差处理后的系统交点误差可以达到最小二乘意义下的极小。最后讨论了实际重磁资料平差处理中任意常数的确定问题。

| Abstract: | Adjustment processing is one of indispensable procedures for marine gravity and geomagnetic data processing. In this paper, based on the least square adjustment theory, the equations for adjusting the survey line network systematic crossover errors are formulated, and a simple method for obtaining the coefficient matrix of above-mentioned equations is given. It is shown from the theoretical computation and practical data processing results that this method has both simple principle and convenient compulter implementation, and the adjusted systematic crossover errors can reach the minimum in a least square sense. Finally, the determination of arbitrary constant in the adjustment processing of practical gravity and geomagnetic data is discussed. |
