土壤水分特性曲线迟滞效应的研究进展 作者:于欣 杨志洲来源:《湖南农业科学》第 01 期 摘 要:研究水分在非饱和土壤中的运动时,迟滞效应不能无视
对迟滞效应近年来的研究现状进行了综述,叙述了产生迟滞效应的因素,有墨水瓶效应、接触角的变化、圈闭气体等,总结分析了现在对土壤水分特性曲线的迟滞效应预测模型的研究,并对此后的研究趋势作了展望

Research status of hysteresis effect was summarized , including ink-bottle effect ,variation in liquid-solid contact angle and air entrapment
Prediction model in hysteresis effect for the soil-water retention curve was comprehensively analyzed
