风化剖面 meaning in Chinese
weathering profile
weatheringprofile
Examples
- Study on features of granite weathering profile in dongguang district
东莞地区花岗岩风化剖面特征研究 - ( 4 ) we defined ssee factor ( surficial soil element enrichment factor ) and wpem factor ( weathering profile element mobility factor ) , and applied them to evaluate the degree of effects of black shales weathering on soil , water bodies and their sediments composition
( 4 )提出了表土层元素富集因子和风化剖面元素迁出因子，用于估算岩石风化对水体及其沉积物、土壤的化学组成影响的程度。 - But in contrast of the research of chemical weathering of other rocks , such as granites and basalts , the research of chemical weathering of black shales both in width and depth still remains much to advance . after reading and investigating widely , we selected lower - cambrian black shales and their weathering profiles in hunan province as research objects of our work at first . then , based on field investigation of weathering status of lower - cambrian black shales and it ' s relationship with soil composition and human activities in hunan , we studied changes of chemical composition such as major and trace elements before and after weathering of black shales by comparison
根据文献阅读和野外调查，本文选择了湖南安化、桃江、望城等地下寒武统黑色页岩及有关风化剖面作为研究对象，并在查明湖南下寒武统黑色页岩的风化现状及其与土壤组成、人类活动的关系的基础上，对比研究了黑色页岩风化前后主量和微量元素等化学组成的变化，探讨了元素的富集和迁移转化机制以及黑色页岩风化与区域环境质量的关系，得出了如下几点主要成果和认识： ( 1 ) ti是黑色页岩风化过程中的“不活动”元素，可作为参照元素，对其它元素的活动性进行质量平衡计算。
