Gongye shui chuli, 2019 探讨了饱和吸附氨氮天然沸石的再生机理和最佳化学再生条件。结果表明，沸石的再生存在2个途径：碱性溶液对NH4+的解吸，以及碱性溶液对沸石表面形态的改变。饱和吸附沸石的最佳再生条件：NaOH质量分数为4%，再生时间4 h，再生温度60 ℃。沸石经过25次再生后，吸附能力保持在85.2%，每次再生平均丢失0.6%，具有工业应用的可行性。

The End of the Observable Infodemic: Privatised Observability and Public Health Monitoring
Policy &Internet, Volume 18, Issue 3, September 2026.ABSTRACT Infodemiology and infodemic management rest on a premise so foundational that it is rarely stated: health information behaviour leaves traces that researchers and public institutions can observe. This paper argues that the premise is dissolving.

, 2007 研究了不同调控措施下辽东栎灌丛再萌生株各生长因子的特征,分析了不同的人为调控措施对辽东栎次生灌丛再萌生能力的影响.结果表明,人为调控对辽东栎再萌生株的发生与生长有着重大影响.调控强度大,再萌生株的数量、高度较小,基径、单株生物量较大;调控强度小,再萌生株的数量、高度较大,基径、单株生物量较小.在辽东栎种群的更新过程中,幼苗与幼树间存在着明显的瓶颈现象,经过激烈的竞争生长,只有少数才能进入下一个生长季.生长季前清除所有再萌生株后,由于当年生长季调控措施的不同,再萌生能力出现差异.调控后 ...
