| 中文摘要: |
| 样品粒度是粉体地质标准物质的一项重要特性指标。长期以来地质标准物质的粒度一直是采用筛分法或沉降法检测，最终大多以加工样品通过一定筛目（一般为-200目）的比例来表达；近年来超细标准物质研制引入了以激光粒度仪为代表的粒度检测与分析的现代方法，并可以直观的粒度分布图和简洁明晰的特征粒径等多种方法来表达粒度分布特征，大大提升了粉体地质标准物质粒度分布特性的测量及表征水平。文章在前期采用激光粒度仪测量超细标准物质粒度分布特征工作的基础上，用此法测量了当今广泛使用的典型地质标准物质的粒度分布，为这些标准物质的正确使用和取样不确定度评价提供了重要依据；同时就今后地质标准物质乃至地质分析样品的粒度检测与表征提出建议。 |
| 英文摘要: |
| The particle size is a very important characteristic index for geological powder reference materials. For a long time, the particle size of geological reference materials had been determined by sieving analysis or settlement separation, and expressed in percentage of that part which passes through a certain mesh screen (normally -200 mesh). In recent years, laser particle size analyzer, reflecting the modern techniques for particle size determination, had been introduced into the preparation of ultra fine size reference materials. In turn, the expression model of particle size was substituted by the intuitive particle size distribution plot and specific particle sizes. The introduction of this technique markedly improved the determination and expression levels of particle size of geological powder reference materials. In this paper, the particle size distribution was determined by laser particle size analysis technique for typical geological reference materials that had been widely used. The purpose of this study is to provide a rational and practicable basis for the usage of those reference materials and their uncertainty evaluation. In addition, some suggestions were also presented for the further study on the determination and expression of particle size for geological reference materials and other geological analysis samples. |
