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.
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.
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.
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.

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.
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.
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.
这个设置将对软件排除热噪点、背景噪声尖峰以及宇宙射线有用。
This will prevent the software from accepting hot pixels random background noise peaks or cosmic ray strikes as real objects.

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.
