| 目的 研究适用于空气中沙尘粒子粒度监测方法。方法 对比研究迎风拦截采集和沉降采集两种采样方式的采集效果和样本差异， 讨论湿法激光粒度分析法和扫描电镜粒度分析法两种方法的准确性和适用性。结果 沉降采集获得的样品量要大于迎风拦截采集， 两种采集方式获得样品的粒度分布也存在显著差异。在沙尘样本粒度分析上， 湿法激光粒度分析较扫描电镜分析更为适用。结论 可结合沉降采集与迎风拦截采集进行沙尘样本采集， 利用湿法激光粒度分析掌握其粒度分布。 |

| Objective To investigate a monitoring method of particle size of dust sands in the air. Methods The collection effect and sample difference by the two different collection methods, i.e., the windward intercepting collection way and the static balance collection way, were compared to discuss the accuracy and suitability of the wet laser particle size analysis and the SEM particle size analysis. Results The static balance collection way got a lager sample amount than that by windward intercepting collection way, and also the particles sizes were obviously different by this two collection ways. On the aspect of particles size analysis, the wet laser particle size analysis was more suitable than SEM. Conclusion The static balance collection way can be used in combination with windward intercepting collection way to process sand collection, and the wet laser particle size analysis can be used to grasp the particle size distribution. |
