763长周期地震仪的标定计算,大多根据《763长周期地震仪仪器标定法》V_(max)-σ~2经验对照表,按照选定的 V_(max)查出相应的σ~2,然后计算动态放大倍数。由于多套仪器的 l_0,J_1、j_2不尽相同,所以尽管保证 D_1=D_2=1、T_1=15。~s0、T_2=100。~s0,还是可以发现实际计算出的 V_(max)与根据经验对照表选定的 V_(max)并不一致。就是说,这种办法不能准确控制 V_(max)为选定值。至于有的注重保证三个分向的静态放大率 V_0的一致性,根据:
763 long-period seismograph calibration calculation, mostly based on the “763 long-period seismograph calibration method” V_ (max) -σ ~ 2 empirical comparison table, according to the selected V_max found corresponding σ ~ 2, and then Calculate dynamic magnification. Because of the different sets of instruments l_0, J_1, j_2 are different, so although guarantee D_1 = D_2 = 1, T_1 = 15. ~ s0, T_2 = 100. ~ s0, or you can find the actual calculated V_ (max) and the empirical table based on selected V_ (max) are not consistent. That is to say, this method can not accurately control the V_ (max) for the selected value. As for the consistency of the static magnification V_0, which emphasizes the guarantee of three directions, according to:
