Zusammenfassung:	Disclosed are a method and a device for filling a dry-type dewar flask. A dry-type dewar flask (1) provided with a porous absorption material (2) capable of absorbing a low-temperature liquid is filled with a low-temperature liquid, such as liquid nitrogen; and the low-temperature liquid enters a supercooled state by means of vacuum-pumping or adding liquid helium, etc. Additionally providing theporous absorption material (2) to absorb the low-temperature liquid can realize quick and efficient filling and obtain a high-quality cold source. 一种充装干式杜瓦罐的方法及装置，向设有可吸附低温液体的多孔吸附材料(2)的干式杜瓦罐(1)中充装低温液体，如液氮，通过抽真空或加入液氦等方式使低温液体达到过冷态，增加多孔吸附材料(2)对低温液体的吸附，可实现快速高效的充装，并获得优质冷源。
