| 摘 要： | 地形变仪器常用的标定方法可分两类:一类是间接标定法,它通过测定仪器的某几个参数而计算出仪器的格值,由于换算环节多,容易引进系统误差;另一类是直接标定法,它通过给出的一个已知物理量与仪器的输出信号对比来标定仪器的格值,此种方法精确度高,重复性强。大多数地形变仪可以用直接法标定,本文还介绍了用直接法对水平摆倾斜仪和浮子水管倾斜仪的标定。

| Abstract: | Two different methods are often used to calibrate the crustal deformation instrument One of them is indirect calibration.We have calculated the scale value of the instrument by measuring some parameters.Since there are a lot of conversion links,they easily lead to sys- tem error.Another is direct calibration.The scale value is calibrated through comparison of the known physical calibration with the output signal of the instrument.This method is higher accuracy and repetition. Most of the crustal deformation instruments can be calibrated with direct calibration. This article suggests a direct calibration method(expansion bear plate)of the horizontal pendulum tiltmeter and the float water-tube tiltmeter. |
