3He release behavior in amorphous ZrV2 tritide films was analysed systematically by thermal desorption method and static storage method. The results show that there are three helium desorption peaks with 597- 3, 725. 8 and 1 146. 6 K in the films, and the third desorption peak has the most amount of the released helium from the amorphous body. During the static storage time with 2 423 d, release fraction (RF) of 3He atoms in the alloy films fluctuates within 10~5 magnitude and ascends linearly, and the release rate of the 3He atoms doesn't speed up, but can be affected seriously by storage temperature. Comparing with crystal ZtV2 tritide films, the storage helium property of amorphous ZrV2 tritide films is better. The above results also prove that the helium retention property of amorphous alloy is favorable, and it will help peoples to understand helium behavior of materials with a new point of view, and provide a new direction to research storage hydrogen materials with high helium retention.%用热解吸和静态贮存方法对贮氚非晶态ZrV2合金膜中3He的释放行为进行了系统分析.结果显示:3He原子存在597.3、725.8和1146.6 K等3个解吸峰,其中第3解吸峰的解吸量最大,是由非晶态基体中的3He释放形成；在长达2423d的静态贮存期间,非晶膜中3He原子的释放系数始终在10-5量级范围内波动并呈线性上升趋势,但仍未加速释放；贮存温度变化会引起释放系数剧烈波动；与贮氚晶态ZrVz合金膜相比,非晶膜的固氦能力显著增强.上述结果初步证实了非晶合金具有良好的固氦性能,这有助于人们从全新视角认识材料中的氦行为.
