He's using Kepler data to do his agedating too, but he's not focusing on individual stars; instead he's looking at star clusters.
他也利用开普勒天文望远镜的数据做年龄测算，但他并不侧重于个别恒星，而是针对一些星团。

According to the result of environment tritium math-physical model and carbon-14 agedating, think the renew ability of the thermal water in study area is confined and inhomogeneity.
根据环境氚的数学物理模型计算和碳- 14测年结果，关中盆地热水可更新性具有有限性和非均一性特点。

We now know the age of the glaciation accurately from radiometric dating of the carbon-14 in logs buried in the drift.
