KYOKUGEN，极端条件下的量子科学与技术中心，大坂大学，丰中，大坂560-8531，日本（日期：2011年1月7日）在激光驱动冲击载荷下获得了高达55 GPa的液氢的主要Hugoniot。压缩氢气的压力和密度是用石英标准阻抗匹配法测定的。冲击温度与冲击波阵面的亮度无关。氢的Hugoniot数据为凝聚态物质的现代理论提供了一个很好的基准。液氢的初始数密度低于液态氘，这导致在相同的冲击压力下，冲击压缩后的氢比氘具有更高的压缩度和更高的温度。
KYOKUGEN, Center for Quantum Science and Technology under Extreme Conditions,Osaka University, Toyonaka, Osaka 560-8531, Japan(Dated: January 7, 2011)The principal Hugoniot for liquid hydrogen was obtained up to 55 GPa under laser-driven shockloading. Pressure and density of compressed hydrogen were determined by impedance-matching toa quartz standard. The shock temperature was independently measured from the brightness of theshock front. Hugoniot data of hydrogen provide a good benchmark to modern theories of condensedmatter. The initial number density of liquid hydrogen is lower than that for liquid deuterium, andthis results in shock compressed hydrogen having a higher compression and higher temperature thandeuterium at the same shock pressure.
