The net result is that a 5% reduction in the voltage more than doubles the life of the bulb, but delivers 20% less light.

综上所述，减少电压5%能使灯泡的使用寿命延长至少2倍，但是其亮度会下降20%。

New selecting tables are defined based on the effect of torque reduction caused by zero voltage vectors in different speed range.

分析了零电压矢量在不同转速范围内对转矩的减小作用，并设计了新的选择表。

With Internet-delivered music, Dolby's noise-reduction matters more now than in 1965, when Dolby first observed that the voltage of hiss in audiotape outmatched the music by a factor of 1, 000 to 1.
