杠杆式衡器灵敏性与稳定性和重心的关系杠杆式衡器（台、案、杆、地秤）都是采用杠杆平衡原理设计制造的，杠杆的固定点（支点）通过杠杆重心的垂直线时，由于重心与固定点（支点〕的位置不同，便形成三种不同的平衡状态，即：稳定平衡、不稳定平衡、随遇平衡。而衡器上采... Lever weighing instrument sensitivity and stability and the relationship between the center of gravity Lever weighing instrument (table, case, pole, weighbridge) are designed and manufactured using the principle of leverage, the fixed point of the lever (fulcrum) through the lever vertical center of gravity, As the center of gravity and the fixed point (fulcrum) position is different, they form three different balance states, namely: stable balance, unstable balance, with the event of balance.
