  4. Abstract : according to the variation in content of characteristic radioactive nuclide and the close relationship between high - grade associated elements in ore - forming components and gold, the ground gamma - ray spectrometry and x - ray fluorescence slectrometry can be used to reveal the existence of gold mineralization rapidly in field and make semi - quantitative evaluation of gold grade. this is of great significance in guiding field geological sample collection and mountain land engineering

    文摘:通過測定特徵放射性核素的含量變化以及利用成礦組分中一些高品位共生元素與金密切的相關關系，可利用地面伽馬能譜與x熒光測量在現場快速揭示金礦化的存在，同時對金的品位進行準定量評價，以及指導野外地質采樣和山地工程。
  5. These imply that the spatial distributions of the different grades of the arable land, classified by the reference land unit method, reflect reasonably the spatial changes of geomorphological units and soil types. the linear estimation model between comparable productions and the corresponding quality ratings of 210 sample units shows that the coefficient of determination r2 is 0. 876, which means that 87. 6 % of the change of y is explained by the change of x. it is concluded that the arable land quality ratings calcul ated by the method can reflect the biologic productivities of land

    另外，利用210個樣點單元的標準糧產量（ y ）與其對應樣地法土地質量分（ x ）進行線性擬合，判定系數r ~ 2等於0 . 876的含義是指y的變異中有87 . 6是由x引起，表明了樣地法土地質量分的高低較好地反映了耕地的生物生產力水平。
  6. The bareness carbonatite rock in chongqing is about 3. 91 x 104km2, makes up of 50 % of the overall land, and distributes mostly at northeast ( include three gorges reservoir area ) and southeast counties of chongqing

    重慶市碳酸鹽巖出露面積約3 . 91萬km ~ 2 ，約占幅員總面積（ 8 . 24萬km ~ 2 ）的50 ，主要集中分佈於渝東北（其中包括三峽庫區）和渝東南各區市縣。
