摘要：

氢原子（HI）21厘米谱线测量星系内部和周围的气体含量，追踪暗物质的潜力，探测其他调查没有的体积和物体。在未来十年，21厘米线科学将利用新技术，特别是焦平面和孔径阵列，并将看到再电离时代/黑暗时代探测实验和平方公里阵列（SKA）前体仪器的部署。几个旨在探测并最终描述星系际介质再电离历史的实验应该在两三年内得出第一批结果。虽然在z ~ 1到3的星系中进行HI的“精确宇宙学”调查需要SKA的全部收集区域，但是利用现有设施和SKA前体所展示的新颖设施的独特能力的HI线科学的连贯计划将告诉我们实际上有多少富含气体的星系以及它们居住的地方，并将产生星系如何吸积气体的基本见解，形成恒星并与周围环境相互作用。

英文摘要：

The atomic hydrogen (HI) 21cm line measures the gas content within and around galaxies, traces the dark matter potential and probes volumes and objects that other surveys do not. Over the next decade, 21cm line science will exploit new technologies, especially focal plane and aperture arrays, and will see the deployment of Epoch of Reionization/Dark Age detection experiments and Square Kilometer Array (SKA) precursor instruments. Several experiments designed to detect and eventually to characterize the reionization history of the intergalactic medium should deliver first results within two-three years time. Although "precision cosmology" surveys of HI in galaxies at z ~ 1 to 3 require the full collecting area of the SKA, a coherent program of HI line science making use of the unique capabilities of both the existing facilities and the novel ones demonstrated by the SKA precursors will teach us how many gas rich galaxies there really are and where they reside and will yield fundamental insight into how galaxies accrete gas, form stars and interact with their environment.
