响沙与粒径特征和风选程度的关系

Relationship between Sounding Sand,Particle size Characteristics and Degree of Selection by Wind

本文是在国内外学者对响沙的研究、试验和学说的基础上提出了响沙和沙响的区别。实验材料从库布齐沙漠银肯响沙湾取沙样 ,首次对沙的机械组成进行了测定 ,并对沙粒的磨圆度进行了观察。通过对实验结果的分析研究 ,结合马玉明的“共鸣箱”理论 ,提出沙的磨圆度与响沙无关 ,而沙的风选程度导致的粒径特征才是响沙的真正原因。一百多年以来 ,国内外学者提出了大量的学说 ,作了大量的实验去解释响沙这一千古之迷 ,有从气垫理论角度去推敲的 ,有从磨擦理论去分析的 ,也有从剪切面理论去阐释的 ,但从风沙运动规律下所形成的粒径特征 ,即特殊地貌下沙的粒径特征这个角度去分析响沙发声的机理 。

Based on studies, experiments and theories made by scholars at home and abroad on sounding sand, the differences between sounding sand and sand sounding have been put forward in this paper. The experimental materials were samples taken from Yinken Sounding Sand Bend in Kubuqi Desert. For the first time, the mechanical composition of sand has been determined, and observation on sand psephicity has been done. Through the analysis on experimental results, combined with MA Yu ming's theory of resonator, there is no relationship between sand psephicity and sounding sand. And the real reason for sounding sand is the particle size characteristics caused by sand degree of selection by wind.
