摘要
通过对３００ Ｌ液氮杜瓦的结构的热力学分析，提出了对其颈管尺寸、底侧部支撑及绝热方式等方面的重大技术改进， 解决了将３００ Ｌ液氮杜瓦用于贮存和长途汽车运输的技术问题。经测量， 其日蒸发率小于１１％ 。
In his paper we analyzed the structure of the 300L liquid nitrogen vessel with thermal dynamics,and solved the problem of storing and long distance transport of 300L liquid nitrogen vessel by technical improvement of the neck tube size,side bottom support and the adiabatic method.The measurement shows that the daily evaporation rate is lower than 1 1%.
