提出了一种新的差分纳力设备，基于静电刚度减小的圆盘摆和用于测量低于1 μ N的水平力的静电力补偿。在空气中的第一次测量超过50秒的平均时间显示的设施的噪声水平为42 pN。本文介绍了功率为7 mW（F（L）= 47 pN）的红色He-Ne激光器的光压测量方法和结果。对于1 nN的待测力和50 s的测量持续时间，器械的力测量不确定度低于5%。
A new differential nanoforce facility, based on a disc-pendulum with electrostatic stiffness reduction and an electrostatic force compensation for the measurement of horizontal forces in the range below 1 mu N, is presented. First measurements in air over an averaging time of 50 s show a noise level of the facility of 42 pN. The method and the results of measuring the light pressure of a red He-Ne laser with a power of 7 mW (F(L) = 47 pN) are presented. The force measurement uncertainty of the device is below 5%, for a force to be measured of 1 nN and a measuring duration of 50 s.
