horizontal pendulum tiltmeter

基本解釋

It can replace traditional horizontal pendulum tiltmeter completely.
它完全可以取代傳統(tǒng)的水平擺傾斜儀。
In this paper, formulae of calculating best operating position of horizontal pendulum tiltmeter are derived, choice of precision and parameter are discussed.
本文推導(dǎo)出水平擺傾斜儀擺桿初始平衡位置的計(jì)算公式，竝對(duì)其精度及各蓡數(shù)的選取進(jìn)行了分析。
Since 1976, by using the non—damping horizontal pendulum tiltmeter at the range of 1.7"—5" period. we have recorded one wave anomaly signal before a series of strong earthquakes respectively.
六年來(lái)，我們用無(wú)阻尼水平擺地傾儀，在1.7秒—5秒的周期範(fàn)圍內(nèi)，在一系列的強(qiáng)震發(fā)生前，分別記錄到了一種明顯的波動(dòng)異常。
