By using the further extended tanh method [Phys. lett. A 307 （2003） 269; Chaos, Solitons ＆ Fractals 17 （2003） 669] to the Broer-Kaup system with variable coefficients, abundant new soliton-like solutions and multl-solitonlike solutions are derived. Based on the derived multi-soliton-like solutions which contain arbitrary functions, some interesting multi-soliton structures are revealed.

为研究预应力CFRP加固含中心缺陷和双边缘缺陷钢板的疲劳性能,基于团队自主研发的自黏结型预应力CFRP施加装置,开展了2种缺陷类型和3种缺陷长度下预应力CFRP单面加固含缺陷钢板在拉伸循环荷载下的疲劳试验,分析了试件的两阶段预应力,讨论了有限黏结长度下试件的破坏模式、疲劳寿命以及荷载循环次数-钢板表面应变分布规律。利用ABAQUS建立有限元模型,通过计算结果分析了不同疲劳裂纹长度下钢板、CFRP和胶层的应力分布,讨论了胶层刚度的退化规律,探讨了CFRP和预应力对裂纹尖端应力强度因子幅ΔK的影响,并基于裂纹闭合效应的Paris模型预测了缺陷钢板的疲劳寿命。结果表明:有限黏结长度下,自黏结预应力CFRP加固钢板具有更长的光滑断裂面,更长的疲劳裂纹稳定扩展区域,可以较好增加钢板的临界裂纹长度;预应力可以提高CFRP的加固效果,使CFRP承担更多的荷载,改善钢板和胶层应力分布,降低缺陷区域应力集中程度,延缓胶层刚度退化时间;CFRP和预应力可以有效降低裂纹尖端应力强度因子幅ΔK,提高钢板疲劳寿命;基于有限元计算的ΔK和裂纹闭合效应的Paris公式,可以准确预测缺陷钢板的疲劳寿命,预测值与试验值误差小于10%。

清末民国的国际法翻译,是推动近代中国法学知识发展乃至转型的重要事件。中文“国际法”在近代中国的翻译,大致经历了从“各国律例”到“万国公法”“公法”“交涉法”,直到“国际法”的发展和转型。但国际法观念和国际法知识在中国的发展,并非是一个单向线性的过程。西方国际法汉译在近代中国法学知识转型中发挥了重要的构建作用,不可盲目认为近代中国只要译入国际法,就会被西方殖民者视作平等的主权国家。实践证明,仅靠翻译国际法,无法构建出普遍的国际秩序。构建自主的中国法学知识体系,不能全靠翻译,但又离不开翻译。

助残赋能是一个动态过程,通过帮助残疾人就业以提高残疾人参与生产生活的能力,进而实现残疾人的社会融合。工作整合型社会企业(WISE)具有公益性与逐利性双重价值属性,在助残赋能中具有独特作用,其作用的发挥是政府和市场共同作用的结果。采用个案研究法,选取X店作为案例,从价值层面、资源层面以及运营层面分析WISE参与助残赋能的行为逻辑与目标定位。研究发现,WISE正面临公益性与逐利性目标设定错位、资金来源不持续、市场资源获取困难、经济效益不稳定、扩张困难等困境。从政府与市场关系角度来看,该困境正是由于政府政策规制不足而无法缓解秉持逐利本质的市场对WISE助残赋能造成的消极影响。突破这一困境的关键在于加强政府政策规制,在价值层面,实现从低维度到高维度的助残价值判断标准转向;在资源层面,强化政府责任,帮助链接各方资源;在运营层面,加大对WISE的宣传,推动对优秀社会企业家的培养,以创造一个能够真正实现WISE助残赋能价值的有利环境,充分发挥WISE在助残赋能中的作用。

随着大规模预训练模型的广泛应用,自然语言处理的多个领域(如文本分类和机器翻译)取得了长足的发展.然而,受限于预训练模型的“黑盒”特性,其内部的决策模式以及编码的知识信息被认为是不透明的.以Open AI发布的Chat GPT和GPT-4为代表的先进预训练模型为例,它们在多个领域取得重大性能突破的同时,由于无法获知其内部是否真正编码了人们期望的知识或语言属性,以及是否潜藏一些不期望的歧视或偏见,因此仍然无法将其应用于重视安全性和公平性的领域.近年来,一种新颖的可解释性方法“探针任务”有望提升人们对预训练模型各层编码的语言属性的理解.探针任务通过在模型的某一区域训练辅助语言任务,来检验该区域是否编码了感兴趣的语言属性.例如,现有研究通过冻结模型参数并在不同层训练探针任务,已经证明预训练模型在低层编码了更多词性属性而在高层编码了更多语义属性,但由于预训练数据的毒性,很有可能在参数中编码了大量有害内容.该文首先介绍了探针任务的基本框架,包括任务的定义和基本流程;然后对自然语言处理中现有的探针任务方法进行了系统性的归纳与总结,包括最常用的诊断分类器以及由此衍生出的其他探针方法,为读者提供设计合理探针任务的思路;接着从对比和控制的角度介绍如何解释探针任务的实验结果,以说明探测位置编码感兴趣属性的程度;最后对探针任务的主要应用和未来的关键研究方向进行展望,并讨论了当前探针任务亟待解决的问题与挑战.
