  • 简介:现在的学习试图在差错地区揭示postseismic液体压力的恢复时期,提供进地震复发的卓见。数字建模基于2D被执行在地震差错以内模仿液体活动的简单分层的差错阀门模型。为了表明postseismic液体的特征,处于自然状态迫使,构造运动的干扰没被考虑。postseismic液体压力的恢复时期包括一个suddenchanging时期和一个长得多的波动时期。当模特儿的结果证明那差错渗透和孔是敏感参数并且与在地震差错地区的液体压力的恢复时期相对地成正比。当渗透从10把-15归结为10-18m2,时,恢复时期correspondently从400~2000年增加。上面、更低的液体压力被阀门封口分开,引起他们在相反的趋势的变化。

  • 简介:当流动正在波动时,实验被进行学习流动的特征。试验性的结果显示出流动率和压力落下变化之间的阶段差别。波动的流动率和压力落下之间的这阶段差别为laminar流动被分析。分析证明阶段差别随着流动变化,管子半径,密度和液体的动态粘性的时期变化。波动的管子流动然后数字地被模仿。数字模拟的结果与理论价值和试验性的结果相比。当流动率作为一个正弦波浪与时间波动时,压力落下与一样的频率波动,这被显示出,并且他们之间有阶段差别。
