树木年代学

Dendrochronology study in Kunming is feasible. RES Tree ring chronology has high sensitivity, but STD chronology can explain more population information.

5通过对云南松树轮样本的年代学和气候学分析可知，在昆明地区可以利用云南松进行树木年轮研究，所建立的树轮宽度指数年表中自回归年表的敏感性较高，但去趋势序列年表反映的群体信息更多；轮宽与气候要素的显著相关关系，使利用轮宽变化的指数年表重建气候变化的历史过程具有可能性。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.

如同这个，不仅拒绝放射性和等时线地球年代测定方法，争论基于可争论的假定，而且采用这类冰核和树木年代学测定，树木年代学使得均变论假定一览无遗和暗示了地球比Ussher-Lightfoot日历更为古老。

SFI is a public research institution of national importance, with a comprehensive research programme focusing on biological, ecological, silvicultural and spatial aspects of forests and forested landscape including forest ecology, forest physiology and genetics, forest protection, ecology of forest fauna and hunting, dendrochronology, dendroecology and dendroclimatology, forest inventory, remote sensing and geographic information systems in forestry etc.

该研究所是国家重点研究机构，主要致力于生物学、生态学、造林学和森林空间森林覆盖等领域的研究，其研究范围涉及森林生态学、森林生理学和遗传学、森林保护、森林动物生态学和狩猎、树木年代学、年轮水文学、年轮气候学、森林资源调查、森林遥感和地理信息系统等。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
