| 摘 要： | 随机误差在重磁数据的测量、各种数学变换处理以及正反演计算中普遍存在。重磁反演解的不稳定其原因之一是由于存在随机干扰,在向下延拓、求高次微商等的计算中,常将误差过份放大,使有用异常被严重干扰,无法辨认。作者为研究随机误差对重磁变换的影响,对随机误差在频率域中传播的情况作了深入探讨。

| Abstract: | Random, errors are ubiquitous in measurements of gravity and magnetic data, mathematical transformation processing of various kinds as well as direct and inversed calculations. One of the factors causing the instability of gravity and magnetic inversed solutions seems to be the existence of stochastic disturbance which, during the downward continuation and the calculation of derivative of higher degree, frequently enlarges the errors to an excessive extent, thus distur bing seriously the useful anomalies and making them unrecognizable.With a. purpose of looking into the influence of random errors on gravity and magnetic transformation, the author has made a deep investigation into the propagation of random errors in frequency domain. |
