The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.

The conventional car-following theory is based on the assumption that vehicles will travel along the center line of lanes. However, according to the field survey data, in complex traffic conditions, a lateral separation between the leader and the follower frequently occurs. Accordingly, by taking lateral separation into account, we redefined the equation of time-to-collision （TTC） using visual angle information. Based on the stimulus-response framework, TTC was introduced into the basic General Motors （GM） model as a stimulus, and a non-lane-based car-following model of steady-state traffic flow was developed. The property of flow-density relationship was further investigated after integrating the proposed car-following model with different parameters. The results imply that the property of steady-state traffic flow and the capacity of each lane are highly relevant to the mi- croscopic staggered car-following behavior, and the proposed model significantly enhances the practicality of the human driving behavior model.

利用移动车辆下的车桥耦合振动信号,本文提出了一种基于扩展卡尔曼滤波的桥梁结构损伤识别方法。以常见的简支梁桥为研究对象,将移动车辆简化为半车模型;当车辆以一定速度行驶时,桥梁的强迫振动响应作为扩展卡尔曼滤波算法的观测值,通过扩展卡尔曼滤波算法的时间更新和观测更新过程,实现了桥梁结构损伤参数的递推修正。为改善结构损伤识别反问题的不适定性,还利用伪测量方法把l1范数正则化过程引入到扩展卡尔曼滤波算法中,在提高了识别精度的同时,有效抑制了损伤的误判。梁桥结构的数值算例分析表明,对于不同的损伤工况、车辆模型参数和行驶速度,本文方法均能准确识别结构损伤的位置与程度,体现出良好的抑制噪声能力。
