A study of Cosmogenic nuclides in the Kirin meteorite is presented in brief here. 本文概括地介紹了吉林隕石宇宙成因核素的研究。
Key Words: Charles Jencks, Modern Science, Cosmogenic Architecture, Green Architecture ,Deconstructivism, Hi-tech Architecture. 關(guān)鍵詞:查爾斯詹克斯,現(xiàn)代科學,宇源建筑,綠色建筑,解構(gòu)主義,高技派建筑。
This situation has improved recently with the advent of surface exposure dating (SED) using in-situ terrestrial cosmogenic nuclides. 由于可確定時代的資料缺乏,絕對年代學的建立非常困難。
The concentration of cosmogenic nuclides, such as beryllium 10 and aluminum 26, in surface samples is proportional to the elapsed time since exposure.My M.I. 由地表取得的樣本中,宇宙源核種(例如鈹10與鋁26)的累積,與巖石露出地表的時間長短有關(guān)。
Collectively, the evidence from landscape studies, cosmogenic nuclides and thermochronometry supports the idea of rapid uplift sustained over very long periods. 綜合地形景觀研究、宇宙源核種以及溫度計時器所提供的證據(jù),都支持快速的抬升已經(jīng)維持了很長的時間。
