新形势下,以《联合国海洋法公约》为核心的海洋法体系在应对海洋治理中的传统安全问题和非传统安全问题时呈现一定的不适应性。普芬道夫自然法哲学中的社会性义务要求社会主体承担不损害他人正当权益的普遍义务,具备此种消极调和特征的公平原则强调规则与历史演替中的社会关系保持一致,主要表现为在承认变化的基础上适应变化。通过将适应理念嵌入海洋法体系,补充法治理念的内容,并表现为面向未来的开放式规则、利益相关者的多元参与和《联合国海洋法公约》的演化解释,海洋法将更加灵活地调整权利义务关系。适应性海洋法治理念具备内在延展性,能够为解决南海问题、日本倾倒核污水等海洋危机以及未来可能出现的类似问题提供借鉴思路。中国的综合实力不断提高,海洋利益诉求也随之变化拓展。中国需要兼顾本国利益与国际社会整体利益,适时调整立场态度,通过建立适应性的国内涉海法律体系、转化参与国际海洋治理的法律逻辑,实现国内涉海管理和全球海洋治理的相互协调。

采用分子动力学方法模拟了[100]单晶铝在等冲量斜波和方波作用下的形变和层裂行为,分析了加载波形与层裂行为之间的相关性。研究表明,脉冲形状与热力学路径的协同作用影响了材料层裂。不同加载波形下单晶铝层裂强度的差异并非受缺陷主导的非均匀孔洞形核影响,而是由不同热力学路径下温升的差异决定。例如:当最大加载速度为3.00 km/s时,单晶铝均经历均匀层裂,但斜波加载下铝的层裂强度较方波加载时提升56.6%。斜波加载会产生逐渐增强的压缩波,使单晶铝产生相比于冲击加载更轻度的损伤。这一现象随着加载速度的提高而变得更加显著。

公平作为法哲学的基本范畴,与正义等其他法哲学基本范畴长期而广泛地存在混淆状态,从而限制其充分发挥本身应有的作用。公平包含内涵本质与外延形式两层维度:“己所不欲,勿施于人”是公平的核心内涵;“居中裁判,平之如水”是公平的重要内涵。公平的外延形式具有鲜明的特点,其是一种消极的利益与价值调和,与正义、平等、衡平等范畴之间虽然存在紧密联系但具有鲜明的界分。澄清公平的法哲学维度并令其与其他基本范畴既相互区分又相辅相成,具有重要的理论与现实意义,有助于国际国内司法制度的发展与法治的完善。

Facing the dilemma on the recourse for Chinese cultural relics pillaged overseas, China shall get a clear understanding of the international legal situation, strengthen international communication and promote international compromise. Based on this foundation, China shah take rational, beneficial and moderate legal actions to uphold and protect national rights. The recourse on the ground of international custom has been deemed as a failure by the view of the majority; the recourse in a foreign court will almost certainly encounter numerous obstacles in law that are very difficult to deal with, and the recourse in a national court will not only achieve the expected goals but also raise considerable disadvantages. If China hopes to retrieve the pillaged cultural relics by means of international treaty, it is necessary for China to conclude special agreements with relative states. The latter shah exercise best efforts to recover the cultural relics and return them to China at the expense of Chinese tax payers.

Using high aluminum refractory material as substrate at 1400℃, we studied the connections between several oxides such as Fe203, MnOv CuO, and the formation of defects such as coating crack, exfoliation, blistering, erosion, and fading away appeared in the application of high temperature infrared radiation coating. Analyses showed that thermal stress formed during the heating process due to the thermal expansion coefficient differential between the coating and the substrate, and volume effect caused by the crystal transferred when the temperature changed, which resulted in the coating crack and exfoliation. The gas produced by the reactions between components and binder or the components themselves during the heating process caused the coating blistering. The EMPA and XRD analyses show that oxides with low melting point in the penetrating area of the substrate may form eutectic with low melting point and produced thermal defects, which leads to the erosion by penetrating to the substrate. The valent changes of Fe2O3 and MnO2 during the heating process cause the volatilization of the oxides or the pulverization of the coatings, resulting in the coating fades away easily at high temperature for a long time.
