基于载人航天功能模型的系统安全性模糊评价方法研究

对载人航天安全性评价时，需要处理两类不同的数据，即随机性数据和可能性数据。本文根据载人航天过程，初步建立了功能的对象模型，在此基础上，基于模糊规划方法，将两类安全性数据进行了统一处理，并提出了载人航天系统安全性模糊评价的求解方法。

肉鸡烤翅热杀菌过程的热穿透特性及品质动力学

研究了不同含水率(w=30%~40%)肉鸡烤翅在热杀菌过程中(杀菌值F=0~5 min)的热穿透特性、品质变化规律及其动力学.结果表明:随着含水率的降低,罐头冷点加热速率系数fh、冷却速率系数fc、加热滞后因子jh、冷却滞后因子jc均降低;相同升温时间及保温时间下,含水率低的烤翅样品积累的F值更大;F值对烤翅的水分活度aw无显著影响(P0.05);烤翅的硫代巴比妥酸(TBA)值变化遵循零级动力学方程,其变化速率k随含水率降低而增大;低强度的热杀菌有利于改善肉鸡烤翅的剪切力、硬度及咀嚼性,其下降曲线均遵循一级动力学方程,且受热杀菌破坏的速率均随着含水率的降低而减小.     

电润湿显示器件的电场动态响应特性对其性能的影响

选用基于Teflon AF1600为绝缘层的电润湿显示器件,研究了电润湿显示器件的电场动态响应特性对其显示性能的影响,并分析了缺陷产生的机理.结果表明,区域像素电容值显著低于理想电容值的显示器件损坏率高,且开口率较低;区域像素电容值显著高于理想电容值的显示器件阈值电压较高,同时开口率也不理想;区域像素电容值接近于理想电容值的显示器件的显示性能普遍良好.而器件的损耗因数过大降低了像素电容的参考准确性.拆件分析也发现,区域像素电容值低的器件制备过程中引入的Na+,使得溶液电导通性发生改变,致使器件耐压下降;区域像素电容值高的器件,其绝缘层边缘过薄甚至部分无覆盖,致使其灵敏度降低,阈值电压升高.     

Command and control model based on complex information relation integration北大核心CSCD

In order to describe collaborative decision-making process, the command and control model is put forward based on complex information relation integrtion and OODA. The characteristics of individual decision-making are analyzed, the complex information relation is considered as the cause of OODA difficulty to describe collaborative decision-making exactly. From the perspective of armament system of systems combat, the information, data, intelligence and knowledge is defined based on knowledge management and Shannon's entropy theory. The basic element is confirmed and the information flow way is analyzed which in the physical, information, cognitive and social domains. From the perspective of information, the armament system of systems complex networks model framework is put forward based on the idea of using OODA to guide armament system of systems complex networks model design. The data, information, intelligence and knowledge flow is analyzed and the describing meta-model is put forward. Using the reticular structure of OODA to describe collaborative decision-making idea is proposed, the command and control model is put forward based on the idea, the simulating tool ExtendSim is used for simulation analysis and results show that our work offer a reference for innovate command and control thory. ©, 2015, The Journal Agency of Complex Systems and Complexity Science.

阳离子表面活性剂提高低渗透油藏注水效率机理

针对长庆油田低渗透油藏注水困难的问题,采用可见光分光光度计和微电泳仪研究了一种水溶性双阳离子表面活性剂在岩石颗粒表面的吸附特性和对岩石颗粒表面电性的影响规律,选用长庆油田长6地层的岩心,评价了该处理剂的抑制黏土膨胀效果及降压增注能力。结果表明,表面活性剂在岩心颗粒表面的吸附等温线遵循Langmuir吸附规律,与岩心颗粒之间的静电引力较大。吸附后,使岩石表面电势减弱,减弱了黏土的膨胀,对黏土颗粒的运移具有一定的抑制作用,因而能够降低注入水对岩心渗透性的伤害程度,明显提高低渗透油藏注水效率。

茂兰国家级自然保护区拥有世界上同纬度稀有的原生性强的喀斯特森林生态系统.为阐明茂兰国家级自然保护区藓类植物多样性格局及其环境因素,在该保护区石上森林、漏斗森林、喀斯特沟谷（青龙潭）、古梅林和村落5类代表性景观设立了342个样地,系统调查了藓类植物的分布情况,计测了物种和功能多样性指数.342个样地共采集1 668份标本,鉴定到藓类植物319种,隶属106属36科.5个景观类型中,物种丰富度以青龙潭和石上森林的最高,物种多样性以石上森林最高,其次是青龙潭;功能多样性在各景观之间没有显著区别.不同的基质中,石生和树生藓类的物种多样性高于土生藓类植物;石生藓类植物功能趋异度和丰富度指数最高,树生藓类植物的功能均匀度较高.随着林冠郁闭度的增加,地面藓类的物种多样性与功能多样性均显著上升,但是随着草本盖度、土层厚度和基质湿度的增加,这些指标呈下降趋势.随着海拔的上升,石生藓类植物的物种多样性与功能多样性指标呈现上升趋势,而树生藓类呈现下降趋势.茂兰地区藓类植物的物种丰富度与功能丰富度、物种多样性与功能趋异度、物种均匀度与功能均匀度之间均呈极显著的正相关关系（p<0.001）.在喀斯特不同程度的石漠化地区,随着环境林冠郁闭度的提高,藓类植物的物种和功能多样性上升,石漠化环境的改善有利于提高藓类植物的多样性.     

Some interval-valued intuitionistic uncertain linguistic hybrid Shapley operators

Two interval-valued intuitionistic uncertain linguistic hybrid operators cal ed the induced interval-valued intuitionistic uncertain linguistic hybrid Shapley averaging （I-IIULHSA） operator and the induced interval-valued intuitionistic uncertain linguistic hybrid Shapley geometric （I-IIULHSG） operator are defined. These operators not only reflect the importance of elements and their ordered positions, but also consider the correlations among elements and their ordered positions. Since the fuzzy measures are defined on the power set, it makes the problem exponentially complex. In order to simplify the complexity of solving a fuzzy measure, we further define the induced interval-valued intuitionistic uncertain linguistic hybrid λ-Shapley averaging （I-IIULHλSA） operator and the induced interval-valued intuitionistic uncertain linguistic hybrid λ-Shapley geometric （I-IIULHλSG） operator. Moreover, an approach for multi-attribute group decision making under the interval-valued intuitionistic uncertain linguistic environment is developed. Finally, a numerical example is provided to verify the developed procedure and demonstrate its practicality and feasibility.     

Spiking neural P systems with anti-spikes and without annihilating priority as number acceptors

Spiking neural P systems with anti-spikes （ASN P systems） are variant forms of spiking neural P systems, which are inspired by inhibitory impulses/spikes or inhibitory synapses. The typical feature of ASN P systems is when a neuron contains both spikes and anti-spikes, spikes and anti-spikes wil immediately annihilate each other in a maximal way. In this paper, a restricted variant of ASN P systems, cal ed ASN P systems without anni-hilating priority, is considered, where the annihilating rule is used as the standard rule, i.e., it is not obligatory to use in the neuron associated with both spikes and anti-spikes. If the annihilating rule is used in a neuron, the annihilation wil consume one time unit. As a result, such systems using two categories of spiking rules （identified by （a, a） and （a,a^-）） can achieve Turing completeness as number accepting devices.
