We have investigated oxyhalide glass in detail for the blue and green light output. 系统的研究了用于实现蓝绿光输出的卤氧玻璃材料。
With illumination tools, a candlepower measurement doesn't necessarily indicate total light output. 使用照明工具时，烛光的测量并代表总的光输出量。
Nearly all energy comes from the sun,either in a roundabout way or straight from it,in the form of heat rays and light rays. 几乎所有的能量都直接或间接地来源于太阳，以热辐射和光辐射的形式。
