natural isotopic 中文意思是什麼
natural isotopic
解釋
天然同位素-
Tree ring is a kind of natural archives, on which the isotopic analysis is important to study global climate and environmental change. the authors mainly provide a comprehensive introduction to the fractionation models of carbon, hydrogen and oxygen isotope in plants, their research techniques and the extract methods from cellulose. that results show isotopic tracer can record the message of climatic variation and has become a powerful tool for paleoclimate reconstruction and for the modern environment changing research. especially studying on pages, the cellulose isotopic analyses of imbedded old tree ring have become the mainly quantitative means of environmental evolvement. in addition, china is a typical monsoon country, research in tree ring stable isotope seasonal variation can give us a lot of important information on that. up to now, the research techniques and works on tree ring in our country are still in its earlier stage, and remain many limitations. it needs further accumulate basic research materials, intensify regional contrast and intercross studies on relative subjects
尤其是在過去全球變化pages研究中，埋藏古木纖維素中的碳氫氧同位素分析已成為環境演化研究的主要量化手段。另外，對于中國這樣典型的季風氣候國家，開展樹輪穩定同位素隨季節性變化的研究具有重要的意義。我國在樹輪研究方面起步較晚，研究方法和研究內容上也比較簡單，還存在不小差距，既要進一步積累基礎資料，又要做區域對比，加強與相關學科的交叉研究。 -

The fluid, in the jurassic system with natural gas pools, has the similar chemistry and isotopic component, and possesses the same evolution trend, indicate that it probably originates from the upper tr iassic series and mix with the infiltrating fluid inside the jurassic system
有氣藏的侏羅系流體與上三疊統流體的水化學特徵和同位素組成相近，且具有同一演化趨勢，表明它可能來源於上三疊統流體，並與侏羅系內的滲流水發生過混合作用。
