Given a lower packing fraction, the hoop strain in the vessel wall induced by the hydriding/dehydriding reactions was increased with alloy powder size.

在较低粉末填充率的情况下，储氢罐壁上的切线方向应变将随著粉末粒径增大而增加。

Results showed that at a given position on the storage vessel surface, the hoop strain was increased with a higher packing fraction of alloy powders during the cyclic hydriding/dehydriding reactions. This resulted from a larger amount of pulverized fine powders generated by a larger packing fraction of alloy powders.

结果显示，在储氢罐表面之特定位置上，其切线方向应变随著粉末填充率提高而增加，这是由於较高的粉末填充率产生较多的粉碎细小粉末所导致。
