Current modules have 10 percent efficiency and an installed system cost of about $4 per watt.
现在通用的组建效率约为10%系统安装费用需要4元每瓦。
And it does not require much energy to work: in its current form the exoskeleton has just two small clutches which only draw a quarter of a watt of power each.
其在能量上的需求也不大，目前的设计只有两个离合器需要各四分之一瓦的电力。
But his colleagues changed the rules so that the current chief justice, Joseph Watt, could extend his term by two years.
欧帕拉符合这些基本条件，但他认为，他的同事们更改了有关规定，以至于现任审判长约瑟夫·瓦特还可以继续任职两年。
He thought that if current speed every year, the German renewable energy can add 11 too watt words, 10 years when Germany can meet the expected goal.
他认为，如果按目前速度，德国每年可再生能源发电能新增11太瓦特时的话，10年内德国就可以达到预期目标。
The metering error considers the non linear effect of the voltage coil and current coil in watt hour meter under different order of harmonics and different distortion degree of input waveform.
计量误差考虑了电度表电压线圈和电流线圈在不同的谐波次数以及谐波大小时的非线性效应。
