Seepage velocity smoothly change from a steady value to a new steady value, the ratio of the new steady value over the original steady value might increase hundreds of thousand times or even more, but it is always finite.（3）Water-inrush goes with the failure of rock strata, but seepage velocity can not increase unendingly, so seepage flow cant be unstable.

研究表明：由于非Darcy流β因子恒为正值，渗流系统总是稳定的；当渗透特性随时间变化时，渗流速度从一稳定值平滑地过渡到一新的稳定值，新的稳定值与原稳定值之比可以增大到几万至几百万倍，但是总是有限的；突水是岩层结构破裂引起的渗流速度快速或急剧变化，但渗流速度不可能无止境地增大，即渗流不可能失稳。

While emphasizing the conformity of political views of army and civil people, we should also note the variousness of specific interests between them. Under such a circumstance, the organizational leadership should not only enhanced but also improved. Therefore, we must guide peoples from all industries, especially newborn groups and social strata, take use of social, marketing and legal measures to actively explore and establish the new model of harmonious, healthy and organized military-civil relationship to match the new situation of Socialism market economy system.

结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。
