High-Order Soliton Solutions and Hybrid Behavior for the (2 + 1)-Dimensional Konopelchenko-Dubrovsky Equations

引用

Journal of Applied Mathematics and Physics 2024年第7期12卷 2452-2466页

作者： Xingying Li yin ji College of Mathematics and Statistics Jishou University Jishou China

In this paper, the evolutionary behavior of N-solitons for a (2 + 1)-dimensional Konopelchenko-Dubrovsky equations is studied by using the Hirota bilinear method and the long wave limit method. Based on the N-soliton solution, we first study the evolution from N-soliton to T-order (T=1,2) breather wave solutions via the paired-complexification of parameters, and then we get the N-order rational solutions, M-order (M=1,2) lump solutions, and the hybrid behavior between a variety of different types of solitons combined with the parameter limit technique and the paired-complexification of parameters. Meanwhile, we also provide a large number of three-dimensional figures in order to better show the degeneration of the N-soliton and the interaction behavior between different N-solitons.

New Lump Solution and Their Interactions with N-Solitons for a Shallow Water Wave Equation

引用

Journal of Applied Mathematics and Physics 2024年第8期12卷 2836-2848页

作者： yin ji Xiyu Tan College of Mathematics and Statistics Jishou University Jishou China

By employing the Hirota’s bilinear method and different test functions, the breather solutions of HSI equation with different structures are obtained based on symbolic calculation with perturbation parameters. Some new lump solitons are found in the process of studying the degradation behavior of breather solutions. The interaction between lump solution and soliton solution is constructed in the form of lump solution, and the motion trajectory of lump is obtained. In addition, the theorem of lump solitons and N-solitons superposition is given and proved. The superposition formula of lump is derived from the theorem, and its spatial evolution behavior is given.

既有国家安全的研究大多将国家安全状态与过程看作是国家理性建构的结果,忽视了情感因素的重要作用。情感因素可以影响到国家安全信念、国家安全决策、安全共同体和国家安全状态四个环节。亦即国家情感和领导人情感会影响国家安全信念的生成,民众与领导人的情感既能够塑造国家安全决策的制定过程,又可以策略性地推动国家安全政策的落实。国家间的情感依恋和情感信任有助于推动安全共同体的构建与维系。领导精英的情绪控制和运用能力可以促进国家安全状态的达成,因为愤怒与仇恨等原生性情感可能引发国家间冲突,而工具性情感在特定条件下则可以促成国家间的合作。厘清国家安全的情感逻辑有利于完善国家安全理论体系,同时也有助于更加深刻地理解总体国家安全观与全球安全倡议的价值,为实现上述中国的安全方案提供可行的微观路径。

为解决摩擦摆支座在外部荷载激励下不具备抗拔性的缺点,基于电磁原理和半主动控制思想,提出了一种以电磁力为基础,结合传统摩擦摆的电磁吸盘-摩擦摆复合隔震支座(Electromagnetic Chuck-Friction Pendulum System,ECFPS)。介绍了该复合隔震支座的构造特点和耗能机制,并基于电磁原理推导出电磁吸盘吸力以及ECFPS的等效刚度、周期和等效阻尼比等理论公式,建立了ECFPS计算模型。设计并制作了一个缩尺比为1∶3的ECFPS试件,对不同输入电流、竖向荷载和不同位移幅值下的滞回性能进行了试验研究,探究了不同输入电流对抗拔性能的影响。试验结果表明:理论值与试验值吻合度较高,验证了理论公式推导的正确性;等效刚度和单位循环耗能变化明显,两者最大变化幅度分别为19.81%和28.16%;随着电磁吸盘输入电流的增大,ECFPS支座的抗拔性能提高,实现了支座竖向抗拔的功能。
