摘要：Self-healing metals possess the capability to autonomously repair structural damage during service. While self-healing concepts remain challenging to be realized in metals and metallic systems due to the small atomic volume of the mobile atoms, the slow diffusion unless at high temperatures and the strong isotropic metallic bonds, the scientific interest has increased sharply and promising progress is obtained. This article provides a comprehensive and updated review on the developments and limitations associated with the various modes of potentially healable damage induced in metals and alloys, i.e., stressinduced damage, irradiation-induced damage in bulk materials and contact damage in corrosion protective coatings. The spontaneous intrinsic healing mechanisms not requiring external assistance other than the material operating at the right temperature and an assisted healing mechanism with external intervention are reviewed. Promising strategies to achieve self-healing in metals are identified. Finally, we give some prospects for future research directions in self-healing metals.

摘要：目的:吸力式基础具有投资费用低、施工时间短、无噪音和可重复使用等优点,因此被广泛应用在海洋工程领域。本文针对吸力式基础设计中的关键问题,主要综述现有设计理论,指出理论缺陷,并给出设计建议。创新点:综述砂土、粘土和成层土中吸力式基础的安装、回收、基础承载力、基础沉降和服役性能中的关键科学问题和现有设计理论。方法:1.基于文献报道的现场试验和模型试验,针对吸力式基础安装过程中的沉贯阻力、临界吸力和土塞效应,评估现有设计理论的准确性;2.分析粘土和砂土中吸力式基础的完全排水、完全不排水和部分排水条件下静力和循环承载力计算理论;3.针对吸力式基础的长期服役性能,分析荷载引起的基础变形、固结沉降、循环再固结沉降和极端荷载下的"棘轮效应"。结论:1.现有的吸力式基础安装中沉贯阻力计算理论没有普适性;对于临界吸力的计算,由于没有考虑"土拱效应",理论计算值均低估了安装吸力。2.对于粘土中吸力式基础承载力的计算需要考虑循环作用下土体的强度弱化和基础-土间空隙引起的承载力降低,而砂土中基础承载力计算需要考虑排水条件的影响。3.对于吸力式基础的长期服役性能,特别是基础变形的计算,目前还缺少成熟的计算理论。

摘要：在系统层次研究设计的一般规律,以典型机构为实例,讨论结构演变过程,用宏观序参量加以描述,并通过设计机器人动作规划实现序列序参量运算,通过机构设计实例加以验证;用协同学序参量的概念描述行为-结构映射过程,揭示行为-结构映射的内在规律,在此基础上,进一步提出用设计机器人(D-Robot)执行序参量运算实现自动设计和分析,以实现往复运动行为的机构设计为例验证了方法的有效性。提出D-Robot通用模版,并以此为框架编制凸轮机构设计和分析D-Robot动作规划,实现了凸轮机构设计和分析自动设计。输入条件是从动件尖端运动轨迹,输出包括凸轮理论和实际廓线、速度和加速度运动分析、凸轮力分析、动平衡、速度波动及飞轮设计、运动模拟及设计分析报告。
