为了满足体育运动的需要，它必须经常承受高强度的践踏，这要求运动场草坪的坪床具有较强的表面强度、良好渗透排水性和抗板结性，以提供良好的运动性能，并保证草坪草的正常生长。

A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: There are three major design features which can be used either individuallyorin combination to manipulate delivery levels; filtration, paper permeability, and filter－tip ventilation. A conference paper from 1983 says, The challenge would be to reduce the mainstream nicotine determined by standard smoking－machine measurement while increasing the amount that would actually be absorbed by the smoker. Another conference paper, from 1984, says:（5）We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...

英美公司上世纪70年代末、80年代初的一系列内部文献表明，该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道：可分别或联合应用与设计有关的三个要素，即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果，来控制焦油和尼古丁的释放水平。1983年一份会议论文也提到，关键在于，要在提高吸烟者尼古丁实际吸收量的同时，减少可被标准检测方法测定到的含量。1984年另一份会议论文说：我们应当努力达到这一效果并能在检测中蒙混过关。

That is to say,the deformation in roof rock layer have a great influence on the fissure permeability.

可见顶板岩层的变形对裂隙网络的渗透系数有显著的影响。

The reaction characteristics of flocculus formed in the reaction of cationic polymer to hydrolyzed polyacrylamide and the mass ratio of cationic polymer to HPAM in complete reaction were investigated experimentally. The flocculus has good ability to reduce the core permeability and the capability of washout resistance.

室内实验结果表明，阳离子聚合物与阴离子聚合物发生反应可产生稳定的絮状沉淀，完全反应时阳、阴离子聚合物的质量比为 30∶1；当絮状沉淀的浓度较高时，它具有很好的携砂能力，絮状沉淀可使岩心的渗透率降低 88%以上，且具有良好的抗冲刷能力。

Accumulated leukocytes were counted in vivo by acridine orange leukocyte fluorography, and retinal vascular permeability was measured by Evans blue assay.
