化学风化作用 meaning in Chinese
chemical weathering
Examples
- Correlations between strontium isotope of river water and chemical weathering in karst areas , guizhou province
贵州河流河水的锶同位素与喀斯特地区化学风化作用 - Samples and analysis methods hundreds of water samples from the upper reaches to lower reaches of the rivers were collected and stored in acid - washed polypropylene bottles from 1997 to 2001 in major watersheds of china
3条支流的硅酸盐类化学风化作用已达到了较稳定状态，而东江沉积物比西江、北江相 - Comparing with other rocks , black shales are actually a series of sedimentary rocks enriching sulfide minerals , organic matters and trace elements such as v , ni , mo , cu , zn etc . thorough studies of black shales weathering have important theoretical , economic and environmental values
与其它岩石类型相比，黑色页岩是一类富含硫化物、有机质以及v 、 ni 、 mo 、 cu 、 zn等微量元素的沉积岩，对该类岩石进行化学风化作用研究具有重要的理论、环境和经济价值。 - 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沉积物地球化学与化学风化进程和机械剥蚀率化学风化指数与化学风化率属于表征化学风化作用意义不同的函数，前者为相对概念反映流域岩石在原岩基础上己发生淋溶作用的深度，主要受到了气候因子的深刻影响(中国流域沉积物化学风化指数由北到南呈有规则的递增序列，气候因子对风化进程的影响掩盖了岩性的巨大差异) ，而化学风化率含义是指单位流域面积岩石风化淋溶产生的离子绝对总量。
