  2. 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。
  3.

  7. In this paper. flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is studied. according to characteristic analysis, the model of completely mixing reactor in series is introduced to characterize real reactor as a theoretical model. on the basis of analog computing analysis and discussion of theoretical model. by means of pulse tracer method, experiments on residence time distribution ( rtd ) have been done in different conditions including the change of tracer level, feeding flow rate and circulation flow rate. the result shows when the ratio of circulation flow rate and feeding flow rate amounts to at least 4, the flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is very close to the model of completely mixing reactor in series. an amendatory model has been established by the regression method

    作者首先在對反應器進行特徵分析的基礎上，建立了描述中試規模多級外循環流化床生物反應器流動特性的串級全混流模型，並對理論模型進行了模擬計算分析和討論，在此基礎上，作者分別在無循環和有循環（改變示蹤劑用量、流加流量和循環流量）的條件下，利用脈沖示蹤法對一到五級串聯外循環流化床反應器進行了停留時間分佈實驗，結果表明，在循環流量與流加流量的比值達到大於等於4時，中試規模多級外循環流化床反應器的流動特性接近串級全混流模型，通過數據回歸擬合的方法，建立了中試規模一到五級串聯外循環流化床反應器的流動模型。
