We can monitor many parameters and characteristics by measuring TEN, such as surge frequency, spectrum width, threshold current, mode jump and stability of output light power.

通过对激光的电噪声的测量可以监测激光器的诸多参数和特性，如弛豫频率，谱线宽度，阈值电流，模式跳变及输出光功率是否稳定等。

Machines are used where they're worth it: at another station, one tests the power output of finished cells with a flash of light before robotic arms place them into bins according to performance.

机器要用在更能发挥他们价值的地方：在另一个车间里，用一道光来检测成品电池的输出功率，然后依据检测结果使用机器手将他们放在箱子里。

Nanostructures help solar panels absorb light, increasing their power output by 30 percent or more (TR10: Light-Trapping Photovoltaics and solar Cells Use Nanoparticles to Capture more Sunlight).

纳米结构能帮助太阳能电池板吸收光线，提高发电量达百分之三十以上(参见“TR10：光捕捉的太阳光电”和“太阳能电池运用纳米颗粒捕捉更多的阳光”)。

The output from a single workout is only enough to power a light bulb or a laptop for about an hour and saves between two to six ounces of CO2.
