摘　　要：进行了仲氢转化为正氢的制冷效应技术研究,建立数学物理模型,通过理论分析确定仲氢绝热转化过程和节流过程的制冷温度和制冷量,计算了制冷效应用于液氢储罐内低温氢气液化的系数。The research on the refrigerating effect technology of the para to ortho hydrogen conversion was carried out in this article. Based on the mathematic and physical model of the para-hydrogen adiabatic conversion process and the throttling process, the refrigerating temperature and the refrigerating capacity were analyzed theoretically, and the liquefaction coefficient of the gas in the liquid hydrogen tank was calcu- lated according this refrigerating effect.
