The results obtained by calibration curve method are in good conformity with the standard addition method. The recovery of the method is 99.8%, the relative standard deviation is 3.1%. 其标准曲线法、标准加入法的结果相吻合,样品加标回收率为99.8%,相对标准偏差为3.1%。
Experiment shows that when damping coefficient and positive feedback capacity are properly chosen and theoretical amplitude-frequency curve is basically in conformity with actual one, the alias filter can provide high fidelity of transmitted seismic signal. 实验表明,阻尼系数和正反馈电容选择合适,理论计算的幅频特性曲线和实测的幅频特性曲线基本一致,可以实现去假频滤波器对传输地震信号的高保真。
