Abstract:
针对高层信息融合中的不确定性推理问题,提出了直觉云模型和直觉云推理方法。首先,考虑到问题的直觉模糊性和随机性,将云模型与直觉模糊集理论相结合,提出了直觉云模型,实现定性概念与其定量表示之间的不确定性转换;然后,根据专家知识构建推理规则库,设计直觉云推理算法,实现不确定性推理;最后,将直觉云推理方法应用到空中目标攻击意图分析中,说明了直觉云推理方法的有效性和实用性。
To solve the questions of uncertain reasoning in high level information fusion, intuitionistic cloud model and intuitionistic cloud reasoning are proposed. First, considering the intuitionistic fuzziness and randomness, intuitionistic cloud model is proposed by combining the cloud model and intuitionistic fuzzy set theroy. The intuitionistic cloud model can establish transformation of un-certainty between the qualitative concept and the quantitative description. Then, the rules of rea-soning are constructed according to the expert knowledge, the algorithms of reasoning are designed and uncertain reasoning is carried out. Finally, the approach based on intuitionistic cloud reasoning is used for attacking intention analysis of aerial target, which demonstrates the validity and practicability of the intuitionistic cloud reasoning method.

低水分马铃薯淀粉的理化性质及其对鱼糜制品凝胶特性的影响

- , 2015, DOI: 10.13982/j.mfst.1673-9078.2015.3.019
Abstract: 对低水分马铃薯淀粉的微观形貌、结晶结构、糊化特性、热稳定性、冻融稳定性等理化性质进行了测定,研究了低水分马铃薯淀粉的添加对鱼糜制品凝胶特性的影响。结果表明:低水分马铃薯淀粉的水分含量不超过8%,其改性制备过程对淀粉颗粒造成一定程度的破坏使其表面出现皱缩、龟裂,导致其具有较大的无定形区域,表现为较小的结晶度。低水分马铃薯淀粉的起始糊化温度(To)、吸热焓值(ΔH)、析水率和胶稠度分别为57.16 ℃、16.26 J/g、40.83%和80.43 mm,均低于原马铃薯淀粉,且其膨润力(18.83 g/g)显著大于原淀粉(13.06 g/g),表现出较优的理化性质。添加了两种淀粉的鱼糜制品的凝胶强度、持水性和白度的测定数据表明:原淀粉和低水分马铃薯淀粉均可改善鲢鱼鱼糜制品的凝胶性能,增强鱼糜制品的凝胶强度,提升其持水性并且低水分马铃薯淀粉的改善效果更显著,其最佳添加量在8%左右。
In this study, the physicochemical properties such as morphology, microscopic morphology, crystal structure, pasting properties, freeze-thaw stability, and swelling power of ultra-dry potato starch and their effects on surimi seafood were investigated. The results indicated that the water content of ultra-dry potato starch did not exceed 8%. With shrinkage and crack observed on the surface of the starch granule, the ultra-dry potato starch had a larger amorphous region and smaller crystallinity. It formed a gel more easily at a low initial temperature of gelatinization (To, 57.16 ℃) and transition enthalpy (ΔH, 16.26 J/g). Compared to native potato starch, ultra-dry starch exhibited better freeze-thaw stability, higher swelling power (18.83 g/g), and lower gel consistency (80.43 mm), indicating its better physicochemical properties. According to the study, both native and ultra-dry potato starch can improve the gel properties of silver carp surimi products, and the latter showed more significant effects. The optimum addition level of the starch is about 8%.
《树叶裙》与《大屠杀圣母》:澳、英新俘虏叙述的比较分析 A Fringe of Leaves and “Our Lady of the Massacre”: A Comparative Study of Australian and British New Captivity Narratives

- , 2016,
Abstract: 帕特里克·怀特的《树叶裙》和安吉拉·卡特的《大屠杀圣母》大致创作于同一时期,都讲述了一位白人女性在与土著群体短暂接触后又重返"文明"社会的故事。两部作品分别改写了英美文学史上的经典俘虏叙述,都着力描写女主人公的"土著化"过程。但参照后殖民理论的重要概念——"文化转换"可以看出两者在对土著文化的认识上存在着显著差异。《树叶裙》中的女主人公对土著的态度由被动接受到主动认同,其背后折射的是作家对这片土地以及自己作为澳大利亚人的身份的态度转变。土著文化在怀特眼中,只是这片土地"地之灵"的外化。《大屠杀圣母》则体现了卡特对土著文化积极一面的由衷欣赏,女主人公"土著化"的过程展现了借助土著文化对白人文化进行改造的无限可能性。
