Shuitu Baochi Xuebao, 2007 为了比较各类保水剂在同等条件下的性能和应用效果差异,促进保水剂在抗旱节水中的合理应用。本文对国内聚丙烯酸钠、淀粉接枝丙烯酸钠、凹凸棒（无机）/聚丙烯酸钠（有机）、腐殖酸/聚丙烯酸钾4种主要类型农用保水剂进行性能测定,比较其吸水倍率、吸水速率、抗离子特性、pH值、反复吸水性等性能的差异。结果表明,不同类型保水剂的性能差异较大,单一性保水剂聚丙烯酸盐在吸水倍率、吸水速率和保水性等方面表现最好,但反复吸水时吸水率降低较快;淀粉接枝丙烯酸钠第7次吸水时已丧失吸水性;复合型保水剂凹凸棒/聚丙烯酸钠、腐殖酸 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

苗期干旱胁迫及复水对春玉米叶片光能利用特性及抗氧化酶活性的影响
Shuitu Baochi Xuebao, 2018 通过盆栽进行春玉米控水试验，设置3个控水水平(正常供水、中度干旱、重度干旱)、2个水分控制时段(干旱、复水)，研究苗期不同程度干旱胁迫及复水对春玉米叶片光响应曲线、CO2响应曲线及曲线拟合参数和抗氧化酶活性的影响。结果表明：干旱胁迫条件下春玉米叶片对光辐射的利用能力下降，随着干旱胁迫程度增加，叶片最大净光合速率(Pnmax)、表观量子效率(AQY)、光饱和点(LSP)、最大电子传递速率（Jmax）、最大羧化速率(VCmax)均显著下降，而光补偿点(LCP)、超氧化物歧化酶(SOD)、过氧化物酶(POD ...
