Image data from the Swift detectors, normally intended to follow cosmic gamma-ray bursts, were recorded on January 28. The data are combined here, along with a sky survey image of background stars, to show optical and ultraviolet light in green-blue hues and x-rays from the comet in red.

通常用来追踪珈玛射线爆发事件的雨燕号卫星，在1月28日转向鹿林彗星，而所取得的数据再和巡天摄影的背景星场结合，并用绿-蓝色泽及红色来呈现彗星的可见光、紫外光和X射线辐射。

If we now look at this mechanism from an earthbound point of view with the ionising mechanisms starting in the atmosphere and the gamma-rays moving upwards through the D-layer and into the E-layer we see a possible generator for sporadic-E.

如果我们现在看这个机制从一个局限于土地的观点以电离的机制开始在大气和伽马射线搬入向上通过D 层数和E 层数我们看见一台可能的发电器为分散E 。

This produces particles called pions , the 'glue' that holds a nucleus together, and some of these tiny particles degrade into gamma rays.

这一过程产生的粒子叫做介子，介子象胶质封固在原子核的周围，其中有些发生衰变，成为伽马射线。

The basic principle of Gamma Knife is to focus the high energy rays to the target spot and destroy it.

摘要伽玛刀采用立体定向原理将高能射线聚焦照射并毁损靶点组织，因临床治疗有刀的效果而命名。
