【摘要】 针对固体潮汐监测仪器的数据采集结果,研究了其信号连续性判断的约束范围限方法,并利用它有效地区分了标定、地震和突跳等信号。用最小二乘法求多项式拟合方法得到了标定过程中固体潮背景信号的表达式,从而可计算出标定信号的偏移量大小,并得到仪器记录数采曲线的格值。更多还原

【Abstract】 Based on the data collection using the earth tide detecting instrument, a restricting range method to estimate continuity of the signals is studied. This method is able to distinguish calibration from other break signals, such as earthquake. Using the least bi-multiplication of polynomials, an expression of the earth tide during calibration is obtained, by which the offset of the calibration signal and the value of the earth tide recorded curve are achieved.更多还原
