Shuitu Baochi Xuebao, 2021 通过野外采样和室内分析相结合，以广东省赤红壤区花岗岩（G）、第四纪红土（Q）和砂页岩（S）母质发育的林地（FL）、水田（PF）和旱地（UL）土壤为研究对象，分析了土壤团聚体有机碳及其组分和不同形态铁氧化物含量，探究了其对土壤团聚体稳定性的影响及贡献。结果显示：（1）3种母质发育的3种利用方式土壤团聚体均以>0.25 mm为主，2~5 mm团聚体以花岗岩母质发育林地土壤最高（58.51%），0.25~2 mm团聚体以花岗岩（62.93%）和第四纪红土（59.21%）母质发育水田和旱地土壤最高 ...

Shuitu Baochi Xuebao, 2006 通过田间小区试验，研究了不同油菜种植密度与施氮肥对麦茬复种饲料油菜耕层（0～20cm）土壤颗粒组成、水稳性团聚体、微团聚体、粘粒分散率和团聚度的影响。试验结果表明，麦茬复种油菜能提高耕层土壤水稳性团聚体，改善土壤颗粒组成状况；与对照（CK）相比，耕层土壤粘粒分散率呈显著或极显著性降低，〈0．001mm的土壤团聚体破坏率和特征微团聚体比例（〈0．01mm／〉0．01mm）显著降低，而土壤团聚度在油菜苗期为降低趋势，收获期呈显著或极显著性增加，〉0 ...

Surface morphologies of gold films on melting glass surfaces(熔融玻璃基底上金薄膜的表面形貌)
Zhejiang Daxue xuebao. Lixue ban, 2002 研究了沉积在熔融玻璃表面金原子的扩散和凝聚行为.实验结果表明，金原子的凝聚过程具有明显的3个阶段：沉积在熔融玻璃表面的金原子先形成具有特征结构的网状薄膜；然后网孔破裂，凝聚成准圆形团簇；经无规扩散和凝聚，准圆形团簇最终组成大的分枝状凝聚体.准圆形团簇的扩散系数为10-7～10-8 cm2·s-1数量级.实验结果表明：熔融玻璃基底表面的金膜形貌随凝聚时间的变化而变化.

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant
