形变标定格值计算软件

Software for calibration of deformation seismograph

为提高地壳形变观测仪器格值标定的真实性、准确性和可靠性，根据《地震前兆台网运行管理办法》和《地震前兆台网形变观测与运行工作细则》，针对不同测项、不同仪器标定的规范要求及特点，应用Visual Basic语言编制了格值计算软件。本文主要介绍了软件的使用、格值计算、误差检查方法，结果以全国形变台网中心推荐的Word格式保存。对水管仪、水平摆、垂直摆仪直接从原始文件读取数据，提高了标定精度，实现了格值标定的半自动化。本软件已应用于河北省地震前兆数字化台站工作。

In order to enhance the authenticity, accuracy, and reliability of calibration of crustal deformation observation instrument, a calculation software was developed using the programming language Visual Basic, according to 《precursory seismic network operation and management methods》 and 《Net Units precursory seismic deformation job details and operation》, and in allusion to different items, different instruments and characteristics of the regulatory requirements. In this paper, the use of software, calibration computing, error checking methods and results storage in Word format, recommended by the national center of deformation observation network, are introduced. For the water pipe tiltmeter, level pendulum tiltmeter, perpendicular pendulum, the software can read data directly from the original document, improve the calibration precision, implement the calibration semi-automatically. This software has been used in digital seismic precursory work stations of Hebei Province.
