摘要
研究水分在非饱和土壤中的运动时,迟滞效应不能忽略。对迟滞效应近年来的研究现状进行了综述,阐述了产生迟滞效应的原因,有墨水瓶效应、接触角的变化、圈闭气体等,总结分析了目前对土壤水分特征曲线的迟滞效应预测模型的研究,并对今后的研究趋势作了展望。
The hysteresis effect cannot be ignored for studying water movement in the unsaturated soil. 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. Meanwhile, the advanced trends were prospected.
