描述和分析了滤饼横向沟流和纵向大毛细管的形成和发展特征,横向沟流以毛细管入口处结构剪切破坏为基本特征,而纵向大毛细管的形成及进一步扩大,对过滤质量立即产生破坏性影响。滤饼二端的压差与流量过大或剧烈波动是这 2种特殊现象的根本原因。通过对毛细管中非牛顿流动分析,滤饼二端压差与流量的乘积与毛细管内的剪切应力、剪切速率的关系得到初步明确。

针对传统故障树分析方法无法有效处理非精确失效概率的问题,提出了一种新的故障树区间分析方法。利用证据理论,由似真函数和信任函数获得底事件发生的区间概率。基于不确定变量的超椭球描述,构造了故障树区间算子,将底事件发生概率的不确定性传递到顶事件,并设计了求解条件极值的Monte-Carlo仿真算法,从而对故障树进行区间分析。该方法适用于统计数据缺乏或者难以得到实验数据的情况。理论分析和仿真实例表明,本方法合理可行,较好地反映了工程实际情况。
