【摘要】 选用十个随时间趋势性变化的函数作为零漂估计函数项，选用一系列不同周期的正、余弦函数作为周期变化的函数项，建立倾斜仪观测值中所含函数项的数学模型，给出了对上述两类函数按统一标准计算及挑选的方法。对漳州地震台ＳＱ－７０Ｂ倾斜仪资料的计算结果显示这一数学模型基本符合实际；周期等于５０天的振幅，与台湾Ｍ２＞５．０级地震和福建省内ＭＬ≤４．０级地震对应较好。更多还原

【Abstract】 It is presented to seleet ten functions varying tendentiously in time to estimate the drift of tilt observation and to select the Sine and Cosine functions with various period as the function with different period so that the mathematital model of the function terms contained in tilt observations is founded,and the method for selecting and calculating both of the functions mentioned above is given in this paper.The results computed from the data of tilt observation at Zhangzhou station show that the model is coinsident with the actual conditions,tliat the amplitude with the period of 50 days is correspondins to the earthquakes in Taiwan M,>5.0 and in Fujian province ML≥4.0.更多还原
