英文
oxygen isotope method-
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。In this paper, by explored geo - physico - chemical prospecting method for looking for oil in prior prospect, the authors summarize a suit of prospective technique and program, which is valid to oil - geology trait of zhidan area and composed of ; oil gas geo - chemical prospect ( acid degradation of hydrocarbon, absorbed - fluorescent spectrum, ultraviolet radiation spectrum, methane carbon - isotope ) non seismic detection in favorable explorative area which confirmed by chemical prospect ( matural potential, gamma energy spectrum. accurately magnetic analysis ) resistively prospecting in anomalous area which confirmed by physicalprospect successful general evaluation of geo - physicochemical prospect
