摘　　要：运用热力学第一定律对低温液体在贮存、运输转注过程中的热力学特性进行了分析,定量分析、计算了低温液体节流过程的节流汽化率值,提出了减少节流过程所形成的汽化率的有效途径;论证了在大型低温液体贮存站贮罐设计选型时,应根据不同的低温液体液源、液体品质和操作工况等条件进行设计选型;论证了除合理地选择正确的低温液体贮罐结构形式外,还应高度重视低温液体贮罐的安全泄放设计,以确保低温液体贮存站的安全性能、使用性能和技术经济性能均处于最佳状态。The thermodynamic characteristics of cryogenic fluid during its storage, transport and transmission are analyzed with the first law of thermodynamics. The vaporization rates of throttling processes are analyzed and calculated quantitatively, and some effective ways for decreasing vaporization rate of throttling processes ate also proposed. The model selection of storage tanks for large scale cryogenic liquid storage station is discussed from the view of cryogenic fluid type, liquid quality and operation condition. Besides the rational structural form of cryogenic fluid tank, the safe discharge should also be highly emphasized in the design to ensure safety performance, service convenience and technically economic operation of cryogenic fluid storage station.
