gamma ray

Some researchers had thought magnetars wouldn't be massive enough to produce the kind of energy required for a gamma-ray burst.

一些研究者曾经认为磁星的质量不足以产生足够的能量去引发γ射线爆炸。

Gamma-ray bursts cannot be seen by the human eye, but if they could the sky would light up like a camera flash each time they occurred.

伽马射线暴不能被人眼，但如果他们能够将天空照亮了像照相机闪光灯每次发生。

When particles in the jet strike a photon of visible or infrared light, they cause the photon to jump up in energy and become a gamma ray.

当喷流中的粒子撞击到可见光或者红外波长上的光子，将导致光子能量跃迁，形成伽玛射线。

Most gamma ray bursts last for only tens of milliseconds up to a few minutes.

大部分γ-射线爆只能持续从百分之一秒到几分钟的时间。

The probability of a specific interaction occurring depends on the atomic number of the material and the energy of the gamma ray.

发生特殊相互作用的可能性和物质的原子量以及伽马射线的能量有关。

These observations revealed a burst of radio light that coincided with the gamma-ray flares, which usually lasted a few days.

这些观测显示，射电光的爆发跟伽马射线的闪光是同步的，通常会持续几天。

Usually gamma-ray bursts mark the end of a massive star and emission from these events never lasts more than a few hours.

通常，gamma射线爆炸标志着大星球的生命终结，这类事件的发射从不会持续超过几小时。

Last month, we discovered a bright gamma-ray flare from the direction of this star while it was undergoing a huge optical outburst.

在上个月这颗亮星经历一次大规模光学爆发的时候，我们在它所在的方向上发现了一次伽马射线爆发。

Every week, astronomers sight two or three gamma ray bursts (GRBs), short flashes of high-energy radiation from collapsing stars.

天文学家们每周都能看到两三次伽马射线爆发（GRBs）现象，这种现象是恒星塌缩时产生的高能辐射所造成的短暂闪光。

The bubbles display a spectrum with higher peak energies than that of the diffuse gamma-ray glow seen throughout the sky.

气泡结构的光谱呈现出峰值能量高于全天区弥散伽马射线的状态。

NASA's Fermi spacecraft has discovered a pair of enormous gamma-ray-emitting bubbles extending from the Milky Way's center.

美国航空航天局费米太空望远镜发现了源自银河系中心的一对巨大的气泡状伽马射线喷发结构。

Gamma Ray curve is mainly used for the location of lithology and calculate the clay content.

自然伽马曲线主要用于地层岩性划分及泥质含量求取。

These positrons then come into contact with electrons in the body, and the two annihilate, releasing two gamma-ray photons.

正电子与人体组织中的电子发生作用而湮灭，产生两个伽玛射线光子。

however , it is now proposed that the conversion of neutron stars to strange stars is another possible origin of gamma - ray bursts.

不过，近期有研究指出，伽玛射线爆发现象，也可能是由一颗中子星转变为奇异星时所产生的。

That was a Gamma Ray Burst that just slammed into you, but instead of mutating into a rampaging green bahemoth, you die instantly.

伽马射线照在你身上，你不会变异成狂暴的巴赫莫斯，而是马上死亡。

Dr. Vicki Kaspi , a Professor of Physics at McGill University, explores the irradiating effects of a giant gamma ray burst.

VickiKaspi博士，McGill大学物理学教授，研究地球将在巨大的伽马射线风暴辐射下毁灭。

At the point of collision they may release a giant Gamma Ray Burst.

在它们碰撞的那一刻将释放出一个强大的伽玛射线爆发。

What intrigued the researchers about this gamma ray burst is that it flared up four times over a period of four hours.

使得研究人员对该伽马射线暴好奇的是在短短四个小时内它竟燃起了四次。

Gamma-ray bursts (GRBs) are flashes of gamma-ray occurring at cosmological distances, being the most powerful explosions since the Big Bang.

伽玛射线暴是宇宙中的伽玛射线突然增亮的现象，是继大爆炸后最剧烈的爆发。

A diffused gamma-ray glow from the plane of our Milky Way Galaxy is clearly seen across the middle.

从银河系平面中间分散开来的伽玛射线清晰可见。
