  • 樹輪

Examples

  • Isotope ; global change ; tree ring ; lake sediment ; ice core
    同位素全球變化樹輪湖泊沉積物冰芯
  • Oh , red leaves , i ' ve read your poetic message in the tree rings
    紅葉，我在樹木的年輪里讀過你的文章。
  • Later research on tree rings put the date at between 1699 and 1700
    隨后對年輪所做的研究把日期訂在1699至1700年間。
  • Carbon , hydrogen oxygen isotope studies on imbedded old tree ring and paleoclimate reconstruction
    埋藏古木樹輪碳氫氧同位素研究與古氣候重建
  • Also , paleoclimatologists can use data from tree rings , pollen analysis and the local geology to determine the temperatures and precipitation at the time
    此外，古氣候?qū)W者利用年輪、花粉分析、當?shù)氐刭|(zhì)等資料，可以確定當時的氣溫與雨量。
  • For the first 600 years of the 1 , 000 - year chronology , he claims , researchers used tree rings alone to gauge temperature and only those from four separate locations
    他主張，就過去1000年的頭600年而言，研究者只利用樹木的年輪來估計氣溫，而且樹輪只取自四處不同的地點而已。
  • The global change study is one of the most spectacular and interesting environment scientific questions in the 1990 s . the message of global change stores in tree rings , ice core , loess , underground water , lake sediment and deep sea sediment , all these proxies record the information of global change . with the advances in stable isotope techniques , the isotopic tracer records the message of climatic variation and becomes a powerful tool that can understand paleoenvironment reconstruction and modern environment changing
    全球變化研究是90年代以來最為引人注目和關(guān)切的環(huán)境科學(xué)問題之一。全球環(huán)境變化的信息儲存于樹輪湖泊冰芯黃土地下水和海洋沉積物等載體中，隨著穩(wěn)定同位素技術(shù)的發(fā)展，同位素示蹤劑指示環(huán)境變化的信息，成為了解古環(huán)境再造和現(xiàn)代環(huán)境信息變化的一個強有力的工具。
  • According to surface temperature reconstructions for the last 2 , 000 years , there is also sufficient evidence from tree rings , boreholes , retreating glaciers , and other " proxies " of past surface temperatures to say with a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the preceding 400 years
    根據(jù)對過去兩千年地球表面溫度的重構(gòu)所得出的結(jié)論，以及從樹的年輪、地上鑿洞、退后的冰河線和過去地表溫度的其它“代表數(shù)據(jù)”中得出的充足證據(jù)，可以毫無疑問地講，二十世紀最后幾十年的氣溫要比以前四百年中任何有可比性的時期都高。
  • 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(huán)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(wěn)定同位素隨季節(jié)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(nèi)容上也比較簡單，還存在不小差距，既要進一步積累基礎(chǔ)資料，又要做區(qū)域?qū)Ρ?，加強與相關(guān)學(xué)科的交叉研究。
  • According to surface temperature reconstructions for the last 2 , 000 years , there is also sufficient evidence from tree rings , boreholes , retreating glaciers , and other " proxies " of past surface temperatures to say with a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the preceding 400 years
    根據(jù)《過去200年地表溫度重建》顯示，同樣有充足的證據(jù)，例如樹木的年輪，地上開采石油及水源，冰川的融化，以及其他代表性象征，讓人確信地表溫度在20世紀地近幾十年會比以前400年的溫度有所上升。
