摘　　要：以活性石灰为研究对象,对其进行微观分析。通过测定石灰物性,如活性度、石灰体积密度、气孔率、比表面积与孔径等,确定了石灰活性与其物性相互之间的关系。石灰活性度随着体积密度、孔径的增大而减小,随着比表面积气孔率的增大而增大。从活性石灰微孔和中孔的分布范围和积累量来看,石灰中微孔和中、孔的积累量越大,石灰活性度越高。Activated lime was regarded as the research object in the paper, mean while, microscopic analysis on lime was also carried out. Relationshipps between activity of lime and physical properties was confirmed by determining the physical properties of lime, such as activity ,bulk density ,porosity, surface area and pore size etc. The activity of lime decreased following the increment of bulk density and pore size, and increased following the decrement of specific surface area and porosity. From the distribution range and accumulation quantity of micropore and medium pore,the more the micriopore and medium pore in lime was, the higher the activity of lime was.
