物理测量原理作为基础总的看来,称量是以引力的自然规律为根据的。据此,地球的万有引力场在一质量上产生与该质量成比例的一引力。在按杠杆定律工作的机械式天平情况下,一已知质量的重量是比较力。在弹簧秤情况下,比较力是由弹簧的拉伸或扭动产生的。由于各种不同物理测量原理?
In principle, the basis of the physical measurement principle is that the weighing is based on the natural law of gravity. Accordingly, the universal gravitation field of the Earth produces a gravitational force in proportion to the mass on a mass basis. In the case of mechanical balances that work according to the law of leverage, the mass of a known mass is comparatively forceful. In the spring case, the force is caused by the spring tension or twist. Due to a variety of different physical measurement principles?
