1.1普通氢的热物理性质表用于计算工艺设计和操作中氢的压力-体积-温度（PVT）、热力学和传输性质，尤其是与氢燃料电池应用相关的性质。提供了温度在50 K和500 K之间、压力在50 MPa之间的气态氢的表格。这些表格由国家标准与技术研究所根据标准参考数据库产品REFPROP 9.0版开发。

1.1 The thermophysical property tables for normal hydrogen are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic, and transport properties of hydrogen for process design and operations, particularly as they relate to hydrogen fuel cell applications. Tables are provided for gaseous hydrogen at temperatures between 50 K and 500 K at pressures to 50 MPa. These tables were developed by the National Institute of Standards and Technology from a Standard Reference Database product REFPROP, version 9.0.
