1·Natural gamma logging is a kind of most basic methods of well logging in cased Wells which measure with gamma ray detector along well during logging.

自然伽马测井是套管井测井中一种最基本的方法。它以地层自然放射性为基础，测井时用伽马射线探测器沿井眼进行测量。地层中的自然伽马放射性不是一成不变的。

2·Positrons and electrons annihilated each other, emitting gamma rays detected by Fermi's gamma-ray burst detector, researchers said.

正电子和电子会相互湮灭而发射出的伽玛射线，再由费米的爆发检测器所检测到，研究人员说。

3·It activates a gamma-ray detector that will spot a nuclear blast as much as 100 miles away and instantly shut all the airvents. He had it tested before moving in.

它能使伽马射线嗅探器工作——嗅探100英里外核爆炸并立即关闭所有通风口。

4·We avoid the interfere of different elements with the multiple linear regression on spectra and BGO Gamma-ray detector.

采用多元回归分析方法，较好地解决了元素间的干扰问题。

5·The Large Area Telescope is the most sensitive and highest-resolution gamma-ray detector ever launched.

大视场望远镜是最敏感的，并且对伽马射线的发射着有着最高的分辨率。
