图3 206Pb/238U，207Pb/235U年龄比值计算得到的U-Pb协和图 数据点的测试误差1σ（95%置信区间）或者2σ（68%置信区间）以椭圆的形式表示；平行x轴方向代表了207Pb/235U的年龄误差，平行y轴方向代表了206Pb/238U的误差，短轴方向代表了206Pb/207Pb的年龄误差

Fig.3 The U-Pb concordia diagram obtained from the age ratios of 206Pb/238U, 207Pb/235U The test error of 1 (95% confidence interval) or 2 (68% confidence interval) in the form of ellipses. The parallel x axis represents the age error of 207Pb/235U, the parallel y axis represents the error of 206Pb/238U, and the short axis represents the age error of 206Pb/207Pb
