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.

A novel elastic metamaterial is proposed with the aim of achieving lowfrequency broad bandgaps and bandgap regulation. The band structure of the proposed metamaterial is calculated based on the Floquet-Bloch theorem, and the boundary modes of each bandgap are analyzed to understand the effects of each component of the unit cell on the bandgap formation. It is found that the metamaterials with a low elastic modulus of ligaments can generate flexural wave bandgaps below 300 Hz. Multi-frequency vibrations can be suppressed through the selective manipulation of bandgaps. The dual-graded design of metamaterials that can significantly improve the bandgap width is proposed based on parametric studies. A new way that can regulate the bandgap is revealed by studying the graded elastic modulus in the substrate. The results demonstrate that the nonlinear gradient of the elastic modulus in the substrate offers better bandgap performance. Based on these analyses, the proposed elastic metamaterials can pave the way for multi-frequency vibration control, low-frequency bandgap broadening, and bandgap tuning.

相比传统精馏过程多以单塔作为优化对象,将整个精馏系统作为研究对象更有实际意义。将精馏系统总投资费用C_(T)和总热负荷Q作为优化目标,通过计算机COM接口连接Python和Aspen-Plus软件,调用NSGA-Ⅲ算法对精馏系统进行多目标优化。以戊烷分离流程为例,对4塔的理论板数、进料板数8个变量进行优化和分析。优化结果表明,相比较传统优化,多目标优化的表现更优,二者热负荷接近时总投资费用降低5.37%,总投资费用接近时,热负荷降低8.17%。同时分析多目标优化时侧重总投资费用C_(T)的解和热负荷Q的解的不同优化过程。进一步的单变量分析结果表明:由于精馏塔回流比参数的特性,目标函数中热负荷Q受到的影响更大,多目标优化的最优解在热负荷变化平稳后得出。

通过问卷调查山东省临沂市和滨州市4所小学927名不同年级小学生,利用描述性分析和卡方检验分析了小学生交通安全知识与行为特征。调查显示小学生交通安全知识问题平均答对率为84%,良好交通行为平均发生率近80%,小学生整体交通安全认知与行为情况良好。分析表明小学生不同年级在交通安全知识与行为的很多方面有显著性差异;三年级是交通安全认知和行为的转折点;小学生可以划分为低年级(1～3年级)和高年级(4～6年级)2个阶段。研究发现不同学校在交通安全知识与行为的很多方面有显著性差异。在此基础上,提出了考虑学校和年级差异的精细化小学生交通安全教育对策,即考虑学校的差异制定交通安全教育重点;对低年级学生侧重于交通安全知识教育,高年级学生注重交通行为的规范。
