摘要
利用激光粒度分析仪对黄河沙、建筑尘、土壤尘三种典型的开放源的粒度分布进行了测定分析，从测定结果分析得出黄河沙的颗粒比较大，100μm左右的颗粒居多，粒度分布符合正态分布；土壤尘的颗粒大部分集中在10μm～100μm左右，60μm左右的颗粒数最多；建筑尘的颗粒多数集中在90μm～160μm左右。同时，利用图像处理仪对它们的形貌进行了研究分析，为粒度分布进一步的研究提供科学依据。
the analyzer about particle size sediment of three typical of the open-source about the Yellow River, construction dust and soil dust using for Laser Particle Size Analyzer, drawning from the results of analysis that the Yellow River sand particles relatively large ,most of tablets about 100um particle Distribution of the normal distribution; soil dust particles are concentrated in 10um-100um,60um particles around the largest .construction dust particles majority concentrated in the 90um-160um around. At the same time, the using of their image processing for the study of the morphology, particle size distribution for further research to provide a scientific basis.
