摘要
本文提出了向金属—土壤界面充气形成气幕时土壤对金属粘附的九层结构模型,建立了充气时金属—土壤滑行阻力的数学模型,并探讨了接地比压、土壤含水量、气体参数对气幕减阻效果的影响规律。
A Nine-layer Theoretical Model has been put forward to describe the adherence state between so(?) and metal when air curtain is formed to r(?)ce resistance and a mathematical model of metal-soil slide resistance has been established.The rules of the effect of pressure contact- ing ground,soil moisture and air parameters on resistance reduction by air curtain have also been studied.
