  1. 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。
  2. Xinyuan graphite mould plant is in luocun town, nanhai district, foshan city, it is located the intercrossing of guangfo road andjichang road, so ti has convenient communication. after 10 year of development since its establishment in 1995, it has grown into an important manufacturer in the field of graphite products in china. the plant covers an area of 2000m2, it has years of history in producing graphite products and has accumulated rich knowledge and practical experience and cultivated a high quality professional technical group and capable employee team

  4. Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates

    根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。
