The concentrations of zinc nitrate hexahydrate are 0.01 M, 0.025 M, 0.05 M, 0.1 M, 0.2 M, and 0.4 M, respectively.

硝酸锌六水合物的体积浓度分别为0.01M，0.025M，0.05M，0.1M，0.2M 和0.4 M。

Moreover, SEM images reveal that the size (including average diameter and length) of nanorods increases with increasing zinc nitrate hexahydrate concentration. The average diameter increases from ~410nm to ~3.9 μm.

从扫瞄式电子显微镜的影像中可以得知，奈米柱尺寸会随著硝酸锌浓度的增加而增加。
