1·The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars.
从可见光扩展到无线电波,再到 X 射线和伽马射线,天文学总是会发现不寻常的物体,如射电星系、类星体和脉冲星。
2·It turns out that this avalanche of electrons can produce so many gamma rays that some transform into electrons and positrons, and these in turn are hurled out of the atmosphere completely.
原来这些电子雪崩可以制造出如此之多的伽马射线,其中一些转换成电子和正电子,而这些粒子相继被完全甩出大气层。
3·When a piece of antimatter strikes the observatory and collides with "normal" matter, both particles immediately annihilate and are transformed into gamma rays - which Fermi can detect.
当一小块反物质击打天文台并与“正常”的物质相碰撞时,两个粒子都立即湮灭,并转变为伽马射线-费米就可以检测到它。
4·The Fermi Space Telescope is so sensitive to these gamma ray bursts that it doesn't even need to be positioned right over a thunderstorm to detect the TGFs.
费米太空望远镜对这些伽马射线脉冲很灵敏,以至于它甚至不需要调整位置对准雷暴的正上方,就能来探测TGF信号。
5·These high-energy gamma rays, detected by Fermi’s Large Area Telescope (LAT), have wavelengths one-thousandth the size of an atomic nucleus.
这些“费米大天区望远镜(LAT)”所侦测到的高能伽马射线的波长仅相当于原子核大小的千分之一。
1·When these electrons are deflected by molecules in the atmosphere, they emit gamma rays.
当这些电子被大气中的分子所偏转时,它们会发射出伽玛射线。
2·It's derived from bee hives in New Zealand and then treated with gamma radiation.
这种蜂蜜提取自新西兰的蜂巢,然后用伽玛射线进行处理。
3·The previously known most distant object was a short-lived gamma ray burst.
之前所知最遥远的天体是一次短期的伽玛射线暴。
4·Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, cannot break chemical bonds nor cause ionization in the human body.
射频波就是电磁场,但是与X射线或伽玛射线辐射等电离辐射不同的是,射频波不会打破化学键,也不会给人体造成电离辐射伤害。
5·The supernova explosions that create and spread heavy elements also unleash a torrent of high-energy radiation: gamma rays, X-rays, and ultraviolet light.
创造并散播重元素的超新星爆发同样释放出一股高能辐射的激流:伽玛射线,X射线,紫外线。
1·Severely low levels of gamma globulin can lead to an increased risk of some types of bacterial infections.
丙种球蛋白水平过低能导致某些类型的细菌感染的风险增加。
2·The placental globulin is withdraws from the healthy parturient woman's placenta makes, its principal constituent is the gamma globulin.
胎盘球蛋白是从健康产妇的胎盘中提取制成的,其主要成分是丙种球蛋白。
3·Immunoglobulin's type immunoglobulin has two kinds: Gamma globulin and placental globulin.
免疫球蛋白的种类免疫球蛋白有两种:丙种球蛋白和胎盘球蛋白。
1·The radiation data involved detecting low levels of gamma radiation and suspected alpha/beta particulates in air.
辐射数据包括探测低水平的微克辐射和可疑的alpha/beta微粒。
