elemental abundance 中文意思是什麼
elemental abundance
解釋
元素豐度-
The elemental geochemistry characteristics indicate that elements abundance is controlled seriously by grain size of sediment
元素地球化學特徵表明，元素的豐度受沉積物粒度控制明顯。 -
Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins
2沉積物地球化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數，前者為相對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度，主要受到了氣候因子的深刻影響（中國流域沉積物化學風化指數由北到南呈有規則的遞增序列，氣候因子對風化進程的影響掩蓋了巖性的巨大差異） ，而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。
