torsion balance

基本解釋

A portable torsion balance is used for weighing.
用一臺輕便的彈簧秤稱重。
He used a very sensitive torsion balance.
他利用了一架非常靈敏的扭力天平。
Our group started the experimental test of the photon rest mass in 2000, and presented a scheme of the modulation method with the precise torsion balance.
我們實驗室于2000年開始進行光子靜止質(zhì)量的實驗檢驗,并提出了扭秤調(diào)制法檢驗光子靜止質(zhì)量的實驗方案。
The limit could be improved by prolonging the effective free fall duration,thus then the EP test for rotating extended bodies with a torsion balance scheme is proposed.
實驗主要受到陀螺內(nèi)部摩擦耦合的影響,這可通過延長宏觀旋轉(zhuǎn)物體自由下落時間來減小陀螺內(nèi)摩擦影響,隨后課題組提出采用宏觀旋轉(zhuǎn)物體等效原理的扭秤方案實驗檢驗。
Based on traditional torsion balance gravitation constant G is mesured and laser interference is used measure deflect angle. To eliminate environment effect, magnetic field is used.
摘要在扭擺法測量引力常量的基礎(chǔ)上，提出利用激光干涉法測扭轉(zhuǎn)偏角，并采用磁感應(yīng)力來消減周圍環(huán)境的噪聲干擾，能使引力常量G的測量精度有很大提高。
