In many test applications, the voltage and light output of the diode can be measured simultaneously using a fixed source current value.

在很多测试应用中，二极管的电压和发出的光可以利用大小固定的电流源同时测出来。

Using fluorescent and incandescent as light source, basic features of solar cells such as short circuit current, open voltage, maximum output filling factor and so on were measured.

分别采用白炽灯和日光灯作为光源，测量了太阳能电池的伏安特性、开路电压、短路电流、最大输出功率、填充因子、光照特性等基本特性。

Experimental result shows that the method makes the operating voltage of electric-light source maintained at the range required voltage level of power saving.

实验证明，该方法使电光源的工作电压基本保持在所要求的节电等级的电压范围内。

Although the exact mechanism is still not entirely understood, it turns out that illuminating the liquid crystal, applying a voltage across a small region of it, and then turning off the light source causes a small amount of charge to be stored in that region.
