| 图3 元素含量的D/X比值 D/X比值表示皮果衣和丽石黄衣的含量平均值之比. 空心柱表示该元素在两种地衣之间含量差异不显著,实心柱表示该元素在两种地衣之间含量差异显著（独立样本t检验,α=0.05） |
| Fig. 3 D/X ratios of element concentrations. D/X ratio is calculated by dividing mean value of element concentrations in Dermatocarpon miniatum by that in Xanthoria elegans. The hollow bar denotes nonsignificant difference in element concentration between Dermatocarpon miniatum and Xanthoria elegans. The solid bar denotes significant difference in element concentration between Dermatocarpon miniatum and Xanthoria elegans (independent samples t test, α=0.05). |
