资源简介:
Uncertainties estimated from LOWESS fit based on 2SE machine error on 87Sr/86Sr ratio+error in fit; NBS987 87Sr/86Sr=0.710246±0.000012 (n=29; U. Michigan)
以针对87Sr/86Sr比值及其拟合误差的2倍标准误(2SE)仪器误差为基础,通过局部加权回归散点平滑法(LOWESS)拟合得到的不确定度;其中NBS987标准物质的87Sr/86Sr比值为0.710246±0.000012,样本量n=29,测试单位为密歇根大学(U. Michigan)
