Shuitu Baochi Xuebao, 2020 土壤水分入渗的观测方法很多，但在测定坡地生物结皮土壤水分入渗时均存在-定的缺陷。线源入流入渗法是可用于无结皮的坡地土壤水分入渗较为简便快捷的观测方法。以裸土为对照，采用线源入流入渗法和模拟降雨法测定了黄土丘陵区多藻少藓、半藻半藓、多藓少藻等不同类型生物结皮土壤水分入渗过程。结果表明：（1）线源入流入渗法可在不干扰生物结皮的情况下，快速、完整地反映土壤水分入渗过程，获取初始入渗速率、平均入渗速率及稳定入渗速率等重要参数；（2）线源入流入渗法所得研究区不同类型生物结皮的初始入渗速率范围为3~12 mm ...

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.
