This structure is assembled from small cubics? Or corrosion the big bulk materials? This will be helpful when you designate it.

颗粒太不均一了，是团聚体吗？

虽然结构是层状球形，但结构不典型

这种是纳米多级结构么？记得看过一篇论文讲多级结构的，是纳米线生长成簇，最终成为多级结构，觉得楼主的是不是立方体生长成多级结构啊……

怎么生长的还不知道呢

你制备的时候是多长时间啊，可以在最初的时候，中间的时候都取样品做电镜啊，可能最初的时候就是立方体，慢慢生长成这样的，看一下中间态，能够确定生长机理吧应该，呵呵
