摘要
至今仍未见一种有效的标定方法和设备,可直接标定大位移拾振器的线性度。本文介绍了一种标定超低频水平向大位移拾振器线性度的回转标定法,以供讨论。
Up to now there is no effective calibration method and instrument for the large displacement pickup, that may directly calibrate the measuring linearity of pickup. This paper suggests a rotational measuring method for calibrating linearity of the ultra-low-frequency large displacement horizontal pickup.
