When the reaction time elapsed, the changes of the pore surface and average pore diameter become mild and the pore volume reduced drastically and then remain unchanged. 反应时间增长后，小孔表面积与平均小孔直径变化趋缓，而小孔体积则大幅下滑再维持稳定。
Some kind of usual specific surface distribution curve and accumulative total porous volume distribution curve model of coal reservoirs in the basin are summarized in this paper. 总结了鄂尔多斯盆地煤储层几种常见的比表面积分布曲线及累计孔体积分布曲线模型。
