Shuitu Baochi Xuebao, 2020 施加化学改良剂是改良土壤和提高农田水分有效性的重要途径，深入了解化学改良剂对土壤水分运动过程的影响是合理利用化学方法改良土壤的基础。通过开展室内土柱试验研究表施聚丙烯酰胺（PAM）和羧甲基纤维素钠（CMC）2种化学改良剂，分析不同施量的化学改良剂（PAM和CMC）对土壤水分入渗和蒸发特征的影响。结果表明：随着PAM和CMC施加量的增加，不同化学改良剂均降低了土壤水分入渗过程，抑制了土面蒸发过程。综合考虑不同化学改良剂的保水、抑蒸性能，施加CMC的减渗、抑蒸作用高于施用PAM，且CMC施量为0.08 ...

Synthesis and Characterization of Porous Materials with SOD Topological Structure [PDF]
, 2016 具有特定拓扑结构的多孔材料是长期以来的研究热点。无机方钠石和有机-金属框架结构材料ZIF-8都是具有由SOD拓扑结构的多孔材料。由于ZIF-8的孔道结构比方钠石更加灵活，所以其应用范围更为广泛，在气体的吸附分离、有机物的催化降解方面都具有广阔前景。本论文研究了SOD骨架结构材料及其复合多孔材料的性质，解释了这两类多孔材料的合成机制，探究了不同因素对合成结果的影响，具体从以下三个方面展开： 1、本文以廉价高岭土为原料合成方钠石分子筛，通过不同的合成方法得到不同形貌、不同尺寸大小的方钠石分子筛 ...

Integrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Hydrocortisone Aceponate for Chronic Otitis: Long‐Term Efficacy
Veterinary Dermatology, Volume 36, Issue 6, Page 870-878, December 2025.Effective management of otitis externa (OE) requires addressing all contributing factors to prevent chronicity and recurrence. Evidence on the long‐term efficacy of topical corticosteroids in preventing recurrence and secondary infections remains limited. This retrospective noncontrolled study evaluated the efficacy of hydrocortisone aceponate (HCA) in

生物基磺酸盐改良剂对盐碱土的改良效果及油葵生长的影响 [PDF]
, 2018 为研发生态导向型盐碱地治理修复技术解决黄河河套宁夏平原土壤盐碱化,设计不同水平生物基磺酸盐改良剂用量(0、750、1 500、2 250、3 000kg·hm-2)进行盆栽试验。结果表明,生物基磺酸盐改良剂可有效降低盐碱土pH和全盐质量分数,促进油葵生长发育,但施用量过高会起到相反作用。当生物基磺酸盐改良剂施用量为2 250kg·hm-2时改良效果最佳:油葵蕾期土壤pH、全盐质量分数最低达到9.63和0.77g·kg-1,较对照（CK）分别下降6.14%和62.07%;油葵叶片抗氧化保护酶过氧化氢酶 ...
