摘要
本文推导出水平摆倾斜仪摆杆初始平衡位置的计算公式,并对其精度及各参数的选取进行了分析。据此,提出了一种可快速、准确地检测和调整摆杆方位的方法。全国50多个台站运用该法测得了各仪器摆杆的偏角,并重新调准仪器,取得了较好的效益。
In this paper, formulae of calculating best operating position of horizontal pendulum tiltmeter are derived, choice of precision and parameter are discussed. After horizontal pendulum tiltmeter is fast and precisely adjusted by using this method given in this paper, tiltmeter operates in best position. Deflection angles of true operating position of instruments from their best positions, which were installed at more than 50 stations in China, were determined by using this method, and these instruments were readjusted, better effect was taken.
