Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Shuitu Baochi Xuebao, 2007 研究了侵蚀环境退耕撂荒地生态恢复过程中水稳性团聚体的变化规律及其与土壤养分状况及土壤微生物量的关系，结果表明，侵蚀环境退耕撂荒地土壤水稳性团聚体含量迅速提高，在退耕撂荒的第一个10年，水稳性团聚体增大约253．45％。随着退耕撂荒年限的延长，其增大幅度趋缓，第10～50年，水稳性团聚体仅增大16．42％，之后增大幅度更加缓慢，接近一个稳定的水平。相关性分析和回归分析表明侵蚀环境退耕地撂荒后土壤中〉0．25mm水稳性团聚体与土壤的有机碳、全氮、速磷、碳酸钙、微生物量（C，N，P）、CEC关系密切，达到显著（

Shuitu Baochi Xuebao, 2020 为揭示再生水不同灌溉模式下土壤结构性质及导水性能的差异。通过室内模拟土柱入渗试验，以清水灌溉为对照（CK），研究了再生水持续灌溉（RW）、再生水—清水混合灌溉（RW-2）及再生水—清水交替灌溉（ARW）3种灌溉模式对土壤容重、总孔隙度、团聚体稳定性、入渗率及饱和导水率的影响。结果表明：相比CK，各处理容重呈降低趋势，总孔隙度增加，但差异均不显著；再生水灌溉促进潮土>1 mm粒级团聚体向1 mm粒级水稳性团聚体含量对潮土结构稳定性贡献最大；再生水3种灌溉模式下潮土入渗率分别显著增长80.00%~260 ...
