凭借让照相机快门打开时间延长，通常超过1分钟，就能使用发光二极管、闪光灯，乃至闪光物体绘出光线踪迹。
By having a camera's shutter open for extended periods of time, often well over a minute, trails of light can be drawn with LEDs, flashlights, or even sparklers.
此外，这还使发光二极管的寿命延长，远远超出在紧凑型荧光灯照明下，导致降低维修和更换费用。
In addition, the lifespan of the strobed LEDs is extended well beyond that of the compact fluorescent lighting leading to lower maintenance and replacement costs.
这些结果表明，螺旋位错密度的降低延长了激光二极管的寿命。
These results show that reducing the threading dislocation density extends the lifetime of LD.
通过导电极板散热来保证二极管的正常工作，可提高汽车整流器的可靠性，延长整个整流器的使用寿命。
The normal work of the diode is guaranteed by the heat dissipation of a conducting pole plate, which can improve the reliability of the auto rectifier, and prolong the service life of the rectifier.
