这个标记就在宇宙微波背景之中，就是充满整个宇宙的射线。
The imprint in question is in the cosmic microwave background (CMB). This is a bath of radiation that fills the whole universe.

在这样的深度（实验）将有助于减少宇宙射线中的渺子介子造成的背景信号。
Going this deep would help reduce the background signals from cosmic ray muon particles.
南极天文台三大观测宇宙的天文台之一，旨在检测由宇宙大爆炸而产生的大量存在于微光辐射中的扭曲现象，利用天文望远镜对宇宙射线背景进行筛选，再利用星系群的特点确定一个点，即当宇宙射线穿过极热气体时会产生轻微混乱，混乱的那一刻就是所要找的那个点。
The telescopes sift through the background cosmic radiation to find spots where it has been slightly perturbed as it passes through extremely hot gas, a hallmark characteristic of galaxy clusters.
宇宙微波背景几乎但并不都是均匀的，而已知的不均匀的射线被认为是用来标记来自哪个星系(包括恒星系和行星系)。
The CMB is almost, but not quite, uniform, and the known irregularities in it are thought to mark the seeds from which galaxies-and therefore stars and planets-grew.
在这个图像中，钱德拉的X射线以蓝色显示并且以哈勃望远镜的光学成像为背景。
In this image, X-rays from Chandra are shown in blue and are overlaid on an optical image from the Hubble Space Telescope.
威尔金斯从1950年开始利用X射线研究DNA，一年以后富兰克林来到了国王学院，她虽缺少威尔金斯的研究背景，但却接管了相关研究。
Wilkins began studying DNA with X-rays in 1950, but a year later Franklin arrived at King's and without his prior knowledge was put in charge of the research.
本文介绍了宇宙X射线背景的研究近况。
The recent researches of cosmic X-ray background radiation are introduced in this paper.
背景：关于肢端肥大症骨质疏松骨折的资料有限，在活动性肢端肥大症的绝经后妇女中，可以观察到放射线检测到的椎骨骨折发生率增加。
CONTEXT: Data on osteoporotic fractures in acromegaly are limited. An increased prevalence of radiological vertebral fractures was already observed in postmenopausal women with active acromegaly.
背景：真性、假性腰椎滑脱时的影像学表现有许多不同之处，CT能显示小关节的形态学变化，具有普通X射线平片没有的优势。
BACKGROUND: Isthemic and degenerative lumbar spondylolisthesis exhibit different images. CT can display morphological changes of facet joint, which is superior over X-ray films.
