Tree ring

树轮───Tree ring

Detection of climate signal in dendro chronological data analysis: a comparison of tree - ring standardization methods.───在树木年代学资料分析里气候信号的发现:年 轮标准方法的比较.

The relationship between tree ring chronology and climatic factors was studied by correlation analysis.───利用相关分析的方法计算了年轮宽度指数和气候要素间的相关关系,发现5月份的降水与年表的相关最好.

To gauge precipitation, they looked at tree ring widths in lower-elevation oaks, which grow faster in years with higher levels of rainfall.───而为了测定降水量，他们则对长在低海拔地区的栎树的年轮宽度进行研究，因为这些树在雨水比较充沛的年份长得更快。

In addition, he and his colleagues used tree-ring records from other species of trees to reconstruct the region's past climate.───此外，他和他的同事利用其他种类树木的年轮记录重构了此地区过去的气候情况。

Changes in tree ring growth from coastal old-growth also suggest a sudden, widespread subsidence and drowning of roots.───沿海原始森林的生长变化也暗示地面普遍沉降以及树根淹溺。

Paleoclimatology labs around the country, like the one at the National Oceanic and Atmospheric Administration, are therefore busily building databases of tree ring data.

This grove was once home to theoldest known bristlecone, Prometheus, but in 1964, a graduate student namedDonald Rusk Currey was studying tree ring data and got his drill bit stuck inthe tree.
