图3 δ18O(a, c, e)和δ15N(b, d, f)的化学斜率校正实验数据
注:误差棒为对应测量周期观测到的空气标样的外部精度(1σ),部分图因纵坐标量程较大,导致误差棒小于数据点而未显示。
Fig. 3 Chemical slope correction data for δ18O (a, c, e) and δ15N (b, d, f)
Note:Error bars are external precisions observed from air standards(1σ)during the same analytical session,and some error bars are not shown because they are smaller than data points.
