The theoretical packing fraction of the bundle of optical fibers which are arrayed in hexagon with round end-tip is calculated by two methods,and the value of packing fraction was 90.69% which was the same as the value of bundle of optical fibers that were arrayed in hexagon with rectangle end-tip.

采用二种方式推算了光纤采用六边形排列配用圆形端套光纤传光束的理论敛集率，其值为90.69%，这一值同光纤采用六边形排列配用长方形端套的传光束理论敛集率一致。

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.
