Abstract
Using a simple method, a d.c. signal sensitivity of about 0,3×10−9 A/10−9 rad was achieved in an apparatus designed for the measurement of the relative deflection of two torsion balances. This degree of sensitivity allows theEötvös experiment to be repeated with greater accuracy than has been attained hitherto. Signal sensitivity can be raised further by common electronic methods.
Резюме
С помощью сравнительно несложного метода в аппарате, созданном для измерения относительного отклонения двух крутильных балансов, была получена чувствительность сигнала прямого тока в 0,3F 10−9 A/10−9. Эта степень чувствительности позволяет повторить опыт Этвеша с большей точностью. Чувствительность к сигналу можно повышать далее с помощью обычных электронных методов.
