But there is less research on the dynamic property of the light loop of conical refraction.

但是，锥形折射光环的动态特性却少有人研究。

Previous images of the Ring Nebula taken by visible-light telescopes usually showed just the inner glowing loop of gas around the star.

以前由可见光望远镜拍摄的星云环仅仅显示出其内部的环绕着恒星的炽热气体环。

A new serial coupled led system generating open loop nonclassical intensity correlation light field by using a technique of negative feedback is described in the paper.

报道了一种利用光电负反馈技术产生开环非经典强度相关光场的串联耦合led系统。

Similarly, the British-era light-rail loop circling Yangon takes about three hours to ride once around, with no linking bus services into downtown.
