| 摘要: |
| 为探究矿粉表面能与其组成化学成分间的内在关系，通过灰色关联法与主成分分析法，以矿粉的化学成分质量分数为媒介，对采用毛细管上升法测得的5种矿粉、5种化学成分表面能之间的关系模型进行量化分析.结果表明：矿粉的表面能实测值与通过其化学成分表面能计算的计算值之间存在良好的关联度；提出了变化的矿粉表面能、化学成分质量分数与不变的化学成分表面能之间定量关系模型，通过该模型可对不同岩石加工的矿粉，在测得其化学成分质量分数后，直接计算得到矿粉的表面能，可为矿粉表面能在道路工程中应用的深入研究提供理论指导.

| Abstract: |
| To investigate the relationship of surface energy between mineral filler and its chemical compositions, the grey correlation method and principal component analysis method were employed to quantitatively analyze the relationship model measured by capillary rise method. Results showed that measured surface energy parameters of mineral filler agreed with the value calculated on the basis of chemical composition surface energy parameters. A quantitative model related to the changing mineral filler surface energy parameter, chemical composition content and the unchanging chemical composition surface energy parameter was proposed. The surface energy of mineral filler can be determined by this model when the chemical compositions are given. All of the results can provide theoretical direction to further study on mineral filler surface energy for road engineering.
