1) three level seepage/diffuse
三级渗流/扩散
1.
The characteristics of three level falloff and three level seepage/diffuse fields in macrofratures,microfratures and coal matrix blocks(pores) were analyzed,physical model of three level seepage/diffuse of coalbed methane(CBM) was established.
基于煤矿井下宏观裂隙观察、显微裂隙电镜测量、孔隙压汞实验,构建了铁法盆地大兴煤矿7号煤层的三元孔、裂隙结构系统;分析了长焰煤储层宏观裂隙、显微裂隙和煤基质块(孔隙)三级压力降和三级渗流/扩散特征,建立了煤层气三级渗流/扩散场物理模型;通过等温吸附、渗透率和扩散系数实验,数值模拟了铁法盆地DT3井上煤组在排水降压开发煤层气的第3阶段的三级渗流/扩散能力分别为2 126,2 951,149 398 m3/d,指出长焰煤储层煤层气产能受制于宏观裂隙渗流场。
2) diffusion essence
扩散渗流
3) hierarchical structure of tourism flows spreading
旅游流等级扩散
4) flow-stress-damage-convective diffusion
渗流-应力-损伤-对流扩散
1.
Based on that,we consider that while building the salt water intrusion model we must build the mult-field compiled model of flow-stress-damage-convective diffusion and consider the relationship between the tidal cyclic loading,the rock non-uniformity,the rock damage and the salt water intrusion.
针对潮汐循环作用下海水入侵模型的问题,综述了目前国内外海水入侵模型的研究现状,探讨了流固耦合效应和潮汐时域运动效应对海水入侵的影响,指出了建立潮汐循环作用下海水入侵的渗流-应力-损伤-对流扩散多场耦合模型,并考虑潮汐循环加载、岩土非均匀性和岩土损伤与对海水入侵之间的关系,是今后海水入侵模型的主要研究方向。
6) three-dimensional convection and diffusion
三维对流和扩散
补充资料：三级缓存
三级缓存是为读取二级缓存后未命中的数据设计的—种缓存，在拥有三级缓存的CPU中，只有约5的数据需要从内存中调用，这进一步提高了CPU的效率。
