摘　　要：通过对某液氢储罐在复温过程中氧氮含量的测量,研究液氢储罐中固态空气沉积的特点和规律。分别对排液"液相点"取样过程、通入常温氢气"气相"取样过程、残余液氢"液相点"取样过程以及相同情况下"气相点"和"液相点"同时取样过程进行了氧、氮含量的测量和比较,并对试验结果进行了分析,初步得到了液氢储罐中固态空气沉积的规律。The characteristics and laws of sedimentary solid air in liquid hydrogen storage tank were studied by measuring the variation of oxygen and nitrogen concentration in escaped gas during the temperature - rise process of a hydrogen tank. The measure and contrast of the content of oxygen and nitrogen were obtained respectively in the liquid phase sampling process of draining period, gas phase sampling process of pumping in normal temperature hydrogen period, liquid phase sampling process of remnant liquid hydrogen period, both gas and liquid phase sampling process in the same case. The test results were analyzed and the laws of sedimentary solid air in liquid hydrogen storage tank were obtained preliminary.
