摘要
对VAV和ETERNA两种潮汐分析方法的漂移模型、气压回归因子、扰动数据的剔除进行了比较,并利用两种软件对武汉台超导重力数据进行分析,结果表明,迭代后VAV获得的潮汐因子的标准偏差较ETERNA小,而两软件获得的振幅因子理论值的差异在同一个量级。对于长周期潮汐波的求解,VAV比ETERNA更稳定、更方便。
The drift model, regression factor of air-pressure and disturbance eliminating of VAV and ETERNA tide analysis methods are compared and studied theoretically. Then further, the data observed with superconducting gravimeters at Wuhan station are analyzed by use of these two relevant softwares, we can get smaller stand deciation after interation from VAV than ETERNA method, but the differences between the analyzed value and the theoretical amplitude factor is at the same level.
