四川大学学报. 自然科学版, 2012 考虑后视效应和速度差信息的共同作用,基于全速度差(Full Velocity Difference,FVD)模型,提出了一个扩展的跟驰模型.通过线性稳定性分析,得到了该模型的线性稳定性判据;运用非线性分析方法分析了临界稳定点附近交通流密度波的变化,导出了描述交通阻塞相变时的mKdV方程.对扩展模型进行数值模拟和分析,结果表明考虑后视效应和速度差信息的影响能够增强交通流的稳定性,能有效抑制交通阻塞.

Review of Policy Research, Volume 43, Issue 4, July 2026.ABSTRACT The accelerated digitalisation of society has amplified cybersecurity threats and revealed their cross‐sectoral nature. Yet, the policy instruments used to address these challenges remain insufficiently examined. This study conducts a scoping review of 980 academic articles (2007–2024) and applies Hood's NATO framework (Nodality, Authority ...

Jianzhu Gangjiegou Jinzhan为减小模块化钢结构震后损伤，文中提出了一种分布式摩擦耗能连接模块化钢结构体系及其竖向连接节点。设计1榀单跨2层1/2缩尺钢框架试件，通过拟静力试验获取了试件的破坏模式、滞回曲线及骨架曲线，分析了其延性、耗能能力、强度退化、刚度退化及钢绞线应力水平变化等性能指标。基于ABAQUS建立钢框架精细化有限元模型开展参数分析，提出适用于有限元计算的节点简化模拟方法并验证其合理性，在此基础上对整体结构进行弹塑性时程分析。结果表明：试件的平均延性系数为3.93，等效黏滞阻尼系数为0.29，具有良好的抗震性能 ...
