冲积相 meaning in Chinese

alluvial facies

Based on analysis of magnetic effect mechanism of alluvial cohesive soil , according to the distribution and character of river alluvial cohesive soil of first and second terrace of yongjiang river of nanning , pore water chemical characteristic , especially total iron content in pore water and holding form of iron ion in pore water , this text preliminarily divides the river alluvial cohesive soil of first and second terrace of yongjiang river of nanning into two magnetic effect region : reinforced region and weaker region of magnetic effect
摘要在分析粘性土磁效应机理的基础上，根据? 、级阶地河流冲积相粘性土的分布及其特性和孔隙水化学特性，尤其是孔隙水中的总铁含量以及铁离子的赋存形式，将南宁市邕江? 、级阶地河流冲积相粘性土初步划分为磁效应强化区、磁效应较弱区两个磁效应区。
