, 2017 气固两相流系统中普遍存在的颗粒聚团和气泡等介尺度结构对流动有着重要的影响。研究这类结构的数值模拟方法主要分为三类，分别是直接数值模拟（Direct Numerical Simulation, DNS）、离散颗粒模拟（Discrete Particle Model, DPM）和双流体模型（Two-Fluid Model, TFM）。对于工业装置的模拟，DNS和DPM需要的计算量太大，因此主要的模拟方法是TFM。但双流体模型的模拟精度依赖于子模型的准确度 ...

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Jianzhu Gangjiegou Jinzhan, 2021 传统的特高压输电塔塔腿设计是将塔腿结构简化为平面桁架体系进行受力分析。考虑了节点转动刚度对塔腿结构的影响,建立了半刚性连接节点的输电塔塔腿ANSYS模型。进行了平面与空间塔腿模型在不同节点转动刚度下的荷载-位移全过程分析和线刚度比的影响分析,并引入铰接和刚接模型进行对比研究。研究结果表明,节点转动刚度在很大程度上影响塔腿结构稳定极限承载力的大小,主斜材线刚度比会影响节点转动刚度的表达,且两个影响因子在平面和空间模型下都具有不同的变化规律,在用传统平面模型简化计算时应予以注意 ...
