磺化竹红菌素对蛋白质荧光猝灭机理的研究

本文详细研究了磺化竹红菌素对多种蛋白质在溶液状态下的荧光猝灭过程。结果表明，磺化竹红菌素对多种蛋白质荧光猝灭服从Ｓｔｅｎ－Ｖｏｌｍｅｒ曲线。实验观察了温度、粘度、ｐＨ值和盐酸胍对荧光猝灭过程的影响。由于磺化竹红菌素是一两性分子，对于不同蛋白具有不同猝灭过程；磺化竹红菌素对蛋白质的荧光猝灭常数Ｋｑ在１０＾１３ｍｏｌ／Ｌ．ｓ＾－１左右，这说明，磺化竹红菌素是一种比其它蛋白质荧光猝灭剂更加有效的荧光猝灭

混浊水用清水视觉器的研究

针对混浊水环境下对海洋平台管节点焊缝和坝体裂纹检测和监测不易实现的难点,研制了一种基于轴对称射流的混浊水用清水视觉器,其基本原理是在适当区域中,造成一定体积的清水视域并用CCD对目标进行观测.在污水射流浓度分布理论的基础上,推导了静止混浊水中自由清水射流起始段与主体段中的混浊水浓度分布规律,并通过试验对射流的可视域进行了验证.试验表明,这种混浊水用清水视觉器能够在混浊水中造出一定体积的可视域,应用CCD能够对可视域中目标进行观测,其可视域的尺度与射流出口尺寸有关.     

Perspective:Societally connected multimedia across cultures

The advance of the Internet in the past decade has radically changed the way people communicate and col- laborate with each other. Physical distance is no more a barrier in online social networks, but cultural differences (at the individual, community, as well as societal levels) still govern human-human interactions and must be con- sidered and leveraged in the online world. The rapid de-ployment of high-speed Internet allows humans to interact using a rich set of multimedia data such as texts, pictures, and videos. This position paper proposes to define a new research area called ’connected multimedia’, which is the study of a collection of research issues of the super-area social media that receive little attention in the literature. By connected multimedia, we mean the study of the social and technical interactions among users, multimedia data, and devices across cultures and explicitly exploiting the cultural differences. We justify why it is necessary to bring attention to this new research area and what benefits of this new research area may bring to the broader scientific research community and the humanity.     

数控机床手轮进给故障的排故思路

在数控机床加工过程中,由于调整及慢速对刀的需要,通常需要频繁地使用手轮（即手摇脉冲发生器）来控制数控机床伺服轴的运动,因此,在数控机床的诸多故障中,手轮出现故障的次数较多,同时对该故障维修人员的维修水平要求也相对要高。本文以配备有FANuc 0i—mate-TD数控系统的cK0625数控车床为例,系统地介绍了数控机床手轮故障的诊断与分析方法。     

教员队伍变化对教学成果影响的预测模型

为解决院校教员数量波动对教学经验及教学成果的影响问题,基于系统动力学理论,构建影响教员队伍变化对教学成果影响的各元素存量流量图,建立院校教学成果预测模型,并以系统动力学软件Vensim PLE 5.9为平台进行建模仿真。运行结果表明,该模型能进行教学成果趋势的预测,可为考虑教学成果因素时教员应聘与解聘方案的制定提供理论依据。     

北方城市冬季供暖水排入对污水处理厂的水质水量影响分析

北方城市在冬季供暖期普遍存在供暖水直排入污水管道的问题.以北方某污水处理厂为例,探讨并分析冬季供暖水对污水处理厂进水水量水质及污染物削减效率的影响.结果表明:供暖水若以排入污水管道的方式解决,污水处理厂进水量在供暖期突增或以溢流等形式排河,进水浓度大幅下降.供暖水排入污水处理厂对COD削减率影响较小,但对氨氮削减率影响较大,当进水COD浓度较低时(100mg/L),制约脱氮的因素主要为碳源含量,而非C/N值.     

嘉祥县南水北调干线灌排影响处理探讨

南水北调东线一期工程南四湖—东平湖段工程运行后,嘉祥县赵王河以北区域受梁济运河输水影响产生了灌溉排水的限制.文章通过对影响区域原灌排情况的研究,分析了南水北调影响灌排的情况;根据影响情况提出了调引梁济运河南四湖湖水和调引洙水河南四湖湖水两大方案,提出了相应的工程布置设计,测算了相应工程规模.工程实施完成后,效果明显,基本解决了影响区的灌溉影响问题.     

The induced generalized aggregation operators for intuitionistic fuzzy sets and their application in group decision making

In this paper, we present the induced generalized intuitionistic fuzzy ordered weighted averaging (I-GIFOWA) operator. It is a new aggregation operator that generalized the IFOWA operator, including all the characteristics of both the generalized IFOWA and the induced IFOWA operators. It provides a very general formulation that includes as special cases a wide range of aggregation operators for intuitionistic fuzzy information, including all the particular cases of the I-IFOWA operator, GIFOWA operator and the induced intuitionistic fuzzy ordered geometric (I-IFOWG) operator. We also present the induced generalized interval-valued intuitionistic fuzzy ordered weighted averaging (I-GIIFOWA) operator to accommodate the environment in which the given arguments are interval-valued intuitionistic fuzzy sets. Further, we develop procedures to apply them to solve group multiple attribute decision making problems with intuitionistic fuzzy or interval-valued intuitionistic fuzzy information. Finally, we present their application to show the effectiveness of the developed methods.
