古代日本能剧中的宁波人

日本有一部著名的能乐剧《唐船》,讲述的是明代居住在明州的祖庆官人,在一场船只争夺中,被掳到日本,沦为奴仆。他在日本生活十三年,娶了日本妻子,并生有二子。《唐船》的素材,来源于明代倭寇的侵犯和掠夺事件。当时宁波人被倭寇绑架至日本,时有发生,《唐船》的故事,多少折射出一些历史的影子。以《唐船》为线索,聚焦14-16世纪东亚海域世界,挖掘宁波与日本之间发生的贸易冲突、倭寇掠夺等,从而了解一部分特殊人群在日本的生活状况。     

Application of embedded fibre Bragg grating sensors for structural health monitoring of complex composite structures for marine applications

Fibre reinforced polymer (FRP) materials are recently widely applied in the marine industry. The high popularity of composites and safety requirements results in the development of Structural Health Monitoring (SHM) systems. One of the sensors types that can be permanently integrated with a composite structure and used as a part of SHM system are fibre Bragg grating (FBG) sensors. Among FBG sensors advantages small size, high corrosion resistance, and absence of electric current are especially important in monitoring of composite marine structures.The paper presents an application of embedded FBG sensors arrays for evaluation of complex composite structure — a fast patrol boat. The experimental investigations contain spectra analyses for thin laminate sample (skin), a composite sandwich panel and fast patrol boat hull (sandwich structure). The quality of sensors spectra (before/after embedding and loading) was determined using the Pearson correlation coefficient. The relationship between strain and temperature in exploitation range was determined for laminate and sandwich structures. A linear relationship was achieved for both elements. The relationship for the sandwich panel was then applied during strain analyses of the boat composite hull. The utility of designed FBG sensors array for the panel was also verified by sensors responses on impact excitation in chosen points on the structure. The achieved results were then used during designing FBG sensors array embedded into the hull. FBG sensors spectra deformations due to fast patrol boat hull manufacturing process and exploitation as well as strain curves determined for the boat during tests at dry dock and at sea trials are analysed.
