这个同步速度是热靴接口闪光灯能同步并允许正确曝光的最快快门速度，不过还有个办法超越这个限制，这还得再次感谢工程师们。
This sync speed is the maximum your hot shoe flash will sync and provide you with properly exposed images. But wait.
然而，在室外时，如果曝光要求更快的快门速度，只有高速快门同步允许你使用高速快门拍摄，最高可达1/8000s。
However, whether indoors or out, if your exposures require a higher shutter speed, high-speed sync will allow you to shoot at virtually any shutter speed, generally up to 1/8000 sec.
首先利用同步辐射曝光，制作出带有微结构的PMMA模具。
The PMMA mold with a microstructure was fabricated using synchronous radiation lithography.
