临近空间高空气球囊体材料的蠕变试验和数值分析

蠕变是临近空间高空气球囊体材料的重要特性。设计了蠕变试验架,对一种典型的临近空间高空气球囊体材料的蠕变特性进行测试,获得了该材料在常温下的蠕变数据。根据一般高分子材料的蠕变模型,结合测试得到的蠕变数据,分析高空气球囊体材料的蠕变计算模型,确定相关参数。通过有限元分析,仿真了高空气球囊体材料的蠕变量。通过对比根据蠕变模型计算的蠕变量、有限元仿真分析的蠕变量与蠕变试验得到的实际蠕变量,验证了针对DPE-3薄膜建立的蠕变模型和仿真分析的准确性。所采用的蠕变试验测试方法和计算分析结果可为临近空间高空气球的设计和分析提供参考。     

Hybrid warfare through the lens of strategic theory

Hybrid warfare is the latest of the terms/concepts that have been used within the defence community in the last three decades to label contemporary warfare. It has been officially adopted in the core strategic documents of NATO, EU and national governments and has already inspired many articles, policy papers and books; however, this paper is unique in the sense that it analysis the hybrid warfare concept through the lens of strategic theory. It is argued that hybrid warfare does not merit the adoption as a doctrinal concept. Strategic theory instead, which lies at the nexus of all dimensions of warfare, provides a better viewpoint to approach contemporary warfare. It concludes that efforts should be directed towards exploring warfare under the light of eternal principles instead of proving the emergence of new types of warfare.

The Bullet in the Brick: The Materiality of Conflict in Museum Objects

Tangible traces of conflict in visual artefacts can take viewers uncomfortably close to the realities of war—violence, destruction and fatalities. This article questions the evidential force of objects associated with conflict and their eventual display in exhibitions. Through a study of the display of a brick in which is embedded a bullet that is said to have passed through the body of Francis Sheehy Skeffington when he was executed by firing squad during the Easter Rising in Dublin in 1916, this article explores the historical configuration of the brick and analyses its public display in the National Museum of Ireland (NMI). By examining the actions carried out by the NMI in collecting and archiving the object and analysing the narrative strategies of its display, this article considers how the visual aspects of exhibition displays can perpetuate a particular version of historic events and accredits objects with assumed authenticity.     

基于多Agent仿真的装备保障体系供应保障系统设计与实现?

War,vagueness and hybrid war

It has frequently been observed in the literature on hybrid wars that there is a grey zone between peace and war, and that hybrid wars are conflicts which are not clear cases of war. In this paper, I attempt to illuminate this grey zone and the concept and nature of war from the philosophical discussions of vagueness and institutional facts. Vague terms are characterized by the fact that there is no non-arbitrary boundary between entities which lie in their extension, and entities which do not lie in their extension. I apply a theory of vagueness to notions such as “war” and “peace” and go on to suggest that the exact boundary for what counts as a war or not is arbitrary. However, the context in which the conflict occurs determines a range of possible locations for this boundary. The most important contextual parameter is in this respect how the parties to the conflict themselves conceptualize the conflict. I suggest that this can in various ways help us understand grey-zone conflicts.
