2 . the curve of median diameter well showed the grain - size characteristics of the area , which is negatively correspond with the curve of the susceptibility . the median diameter can be regarded as the effectively alternating indication of the environments in the paper
2 、中值粒径曲线很好地反映了本地区的粒度特征，并与磁化率曲线有很好的负向对应关系，所以本文把中值粒径作为环境的有效替代指标。
Based on the topographic features and data of sediment particle size of bed load at the fluctuating backwater reach of liujiaxia reservoir , the streamwise variation and variation process of median diameter of bed load during silting and scouring periods of the fluctuating backwater reach are analyzed , and it can be seen that the turning point for the sediment diameter variation from coarse to fine is located at the outlet of shigou gorge of the fluctuating backwater reach
摘要根据刘家峡水库变动回水区的河段地形特征和历年河床质泥沙粒径级配资料，分析了变动回水区河段淤积和冲刷时，河床质泥沙中值粒径的沿程变化和历年河床质泥沙中值粒径变化过程，并指出粒径分布由粗变细的转折点在变动回水区寺沟峡峡口处。
