nearest surface spacing 邻近集料表面最近间距
The results reveal that the average surface spacing decreases with the increase of volume fraction of aggregates and fineness of aggregates.
研究结果表明：随着集料体积分数的增加和集料细度的提高，平均最邻近集料表面间距减小；
The results show that the surface spacing decreases with the increasing of aggregate fineness as well as with the increasing of aggregate volume fraction.
结果表明，相邻粗集料表面最近间距随集料体积分数的增加以及集料细度的增大而减小。
The surface area of aggregate per unit volume of mortar does have influence on the mean value of the nearest surface spacing, but the ratio between them is not constant.
单位砂浆体积下集料的表面积的变化对邻近集料表面最近间距的平均值有影响，但二者之间的比值并非常数。
