煤储层是一种双重孔隙介质，其孔隙由基质孔隙和裂隙组成，并具有自身独特的割理系统。
一次打比赛，在进第三垒时，我的防滑钉被卡住了，身体朝前栽倒，脚腕却扭向右后方。
在防滑足球鞋的研制方面，耐克公司从来不考虑金钱，时间及生产成本。
虽然我没有反对她的解释，但是我很不满意。事实是我很难在文化认同方面作出割舍。
虽然我不跟他的解释挑战，但这让我很不满意。事实是，我的。
1·The matrix pores in coal play a little role in fluid flow, therefore the permeability derived from well test is the reflection of the percolation flow capacity in cleat system.
煤基质的孔隙性对流体流动影响极小，试井所得渗透率反映的是割理系统的渗流能力。
2·Furthermore, a novel nondestructive and simple laboratory technique has been developed to estimate the porosity and irreducible water saturation associated with the coal cleat network.
开发出一种新型的不损坏样品的简单的实验室技术，估算出与煤层割理网络相关的孔隙度和残余水饱和度。
3·The diffusion of coalbed methane in coal reservoirs is defined that the main process of coalbed methane desorbed from coal matrix pore surface migrated to cleat system.
煤层气在煤储层中的扩散是指从煤基质孔隙表面上解吸的煤层气运移到割理系统的主要过程。
4·The coal cleat pattern in the Kushiro coalfield, Japan, shows some analogy to isolated straight joints.
日本钏路煤田的煤层割理形态类似于孤立的直线节理。
1·DUAL-SIDED ENTRY: The symmetrical double-sided pedal self-locates just by stepping down into the cleat whether the pedal is right side up, upside down or anywhere else in its rotation.
双面锁：在对称的双面踏板上，刚刚踏进楔子踏板下，看看是否位于右侧，这时，倒置或任何其他的旋转。
2·The reinforcing material may be rebar, secured to a load-bearing frame of the building by a cleat (16) having pockets (12) for reception of the rebar ends.
所述加固材料可以是钢筋，其通过具有插座(12)来容纳钢筋端部的楔子(16)而固定于建筑物的承重框架上。
