This totalmodulation index must not exceed unity, or distortion will result.
这总的调制度不得超过一，否则就会产生失真。
2
Total coefficient of modulation of moment for the frame applied horizontal load and vertical load is bigger than that of the same frame applied vertical load.
框架既承受水平荷载又承受竖向荷载时的总弯矩调幅系数比相同结构只承受竖向荷载的总弯矩调幅系数大。

Pulse width modulation is used to reduce the total power delivered to a load without resulting in loss which normally occurs when a power source is limited by a resistive element.
