Experimental research on the effect of entrapped air on one-dimensional ponded water infiltration A Review on Effect of Entrapped Air on Soil Permeability 封闭气泡对土壤渗透性影响的研究进展
Experimental research on the effect of entrapped air on one-dimensional ponded water infiltration 封闭气泡对一维积水入渗影响的试验研究
Fresh snow is full of entrapped air. 刚下的雪饱含着空气。
On the basis of experimental result, the Green-Ampt model for unsaturated infiltration affected by entrapped air in soil is established. 本文利用自由入渗试验、恒定土壤空气压力入渗试验和土壤水力性能试验结果,给出了禁锢土壤空气压力影响下的格林-安姆特模型。
"Hollow" yarns have the properties with light-weight, flexible and more warm, as increased the entrapped air in the yarn, and to gain a stronger yarn for spinning and weaving processes. 空芯纱技术是一种用来提高棉纱性能的技术,它增加了纯棉纱线中的存储空气,并为纺纱和织造过程提供较大强力的纱线。
A Study on Control of Water Column Separation Accompanying Transiet Flow at Two Points by Entrapped Air 用注气法消减两处断流弥合水锤问题的研究
In the progress of infiltration, a part of the volume of soil air is easily surrounded by water flow and closed in soil pores to form entrapped air. Thus the water flow is encumbered and the permeability is decreased, which results in great influence on infiltration. 水分在进入土体的过程中,大部分空气极有可能被封闭在土体孔隙中形成封闭气泡,阻碍水相的流动,使土体的渗透性能降低,从而对土体的入渗能力产生不可忽视的影响。
The effects of dry density, initial water content and soil type on the volume of entrapped air are proposed, and the influencing mechanism of the three factors is discussed. 3. 分析了积水入渗时土柱内封闭气泡的体积与土柱干密度、初始含水量和土类性质的关系,并初步探讨了三种影响因素对封闭气泡体积的影响机理。
