| 4 | 三维快速自旋回波成像技术——SPACE显示文摘二维快速自旋回波(turbo spin echo,TSE)早已成为临床磁共振成像的参考工具,但受到SAR以及T2衰减效应的限制,其数据采集效率仍然难以满足三维成像的需求。基于TSE演化出的SPACE技术,采用可变翻转角的回聚脉冲链设计,解决了临床对TSE三维采集的需求,被逐步应用于各个部位的高分辨率三维成像中。结合应用实例,本文还介绍了SPACE技术的发展过程,以及目前的研究热点。 | 李国斌 张卫军 | 2010 | 磁共振成像2010,1,4: | 61 |
| 5 | 创新2.0时代众创空间的生态模式——国内外比较及启示显示文摘"众创空间"是创新2.0时代创新创业服务机构的集合式概念,是由创客空间、孵化器、加速器等组成的创新新创业服务生态系统。创新2.0时代,欧美国家正积极探索众创空间生态模式,逐渐建立起"创客空间+孵化器+智能化创新(Living Lab)"的垂直、多元化众创空间生态主体结构。相比之下,我国众创空间生态体系尚不健全,"孵化器"一元主导的结构模式明显,在众创空间发展模式、经营主体、功能绩效等方面与国外众创空间存在较大差距。创新2.0时代,我国应积极借鉴国外众创空间发展经验,布局社区化创客空间,建立创新创业智能化升级机制,延长创新创业服务链条,完善众创空间生态体系;积极推进创新创业服务机构市场化改革,发展创新创业服务中介组织,提升众创空间专业化水平,形成市场为主、政府为辅的多元化众创空间新形态,建立起中国特色的众创空间生态体系。 | 解学芳 刘芹良 | 2018 | 科学学研究2018,36,4: | 66 |

| 12 | 基于隐含语义分析的微博话题发现方法显示文摘随着微博的大量普及和关注度的不断提高,微博热点话题发现已成为当前研究热点。针对于短文本、向量空间模型(VSM)文本表示方法存在高维度、稀疏,以及同义多义问题,导致难以准确度量文本相似度,提出一种基于隐含语义分析的两阶段聚类话题发现方法。引入话题热度的概念来选取具有一定关注度的微博文本,用隐含语义分析(LSA)对数据集进行建模;用层次聚类的CURE算法确定初始类中心;用K-means聚类得到热点话题的聚类结果。真实微博数据集的实验结果验证了该方法的有效性。 | 马雯雯 魏文晗 邓一贵 | 2014 | 计算机工程与应用2014,50,1: | 35 |

| 14 | Measure theory of statistical convergence显示文摘The question of establishing measure theory for statistical convergence has been moving closer to center stage, since a kind of reasonable theory is not only fundamental for unifying various kinds of statistical convergence, but also a bridge linking the studies of statistical convergence across measure theory, integration theory, probability and statistics. For this reason, this paper, in terms of subdifferential, first shows a representation theorem for all finitely additive probability measures defined on the σ-algebra A of all subsets of N, and proves that every such measure can be uniquely decomposed into a convex combination of a countably additive probability measure and a statistical measure (i.e. a finitely additive probability measure μ with μ(k) = 0 for all singletons {k}). This paper also shows that classical statistical measures have many nice properties, such as: The set S of all such measures endowed with the topology of point-wise convergence on A forms a compact convex Hausdorff space; every classical statistical measure is of continuity type (hence, atomless), and every specific class of statistical measures fits a complementation minimax rule for every subset in N. Finally, this paper shows that every kind of statistical convergence can be unified in convergence of statistical measures. | CHENG LiXin LIN GuoChen LAN YongYi LIU Hui | 2008 | Science China Mathematics2008,51,12: | 26 |

| 16 | GENERALIZED H-KKM TYPE THEOREMS IN H-METRIC SPACES WITH APPLICATIONS显示文摘The new notions of H-metric spaces and generalized H-KKM mappings were introduced. Some generalized H-KKM type theorems for generalized H-KKM mappings with finitely metrically compactly closed values and finitely metrically compactly open values were established in H-metric spaces. These theorems generalize recent results of Khamsi and Yuan. As applications, some Ky Fan type matching theorems for finitely metrically compactly open covers and finitely metrically compactly closed covers, fixed point theorems and minimax inequality are obtained in H-metric spaces. These results generalize a number of known results in recent literature. | DING Xie-ping(丁协平) XIA Fu-quan(夏福全) | 2001 | Applied Mathematics and Mechanics(English Edition)2001,22,10: | 23 |
| 17 | 《空间的生产》节译显示文摘在数年之前,空间一词有着严格的几何学意义;空间概念使人想到的只是一个空间的区域,在学术意义上,对空间一词的使用通常会伴随诸如“欧几里德”,“匀质的”(isotropic)或“无限的”等形容词,通常给人的感觉是空间在根本上是一个数学概念。因此,要谈及“社会空间”(social space),就会显得有点奇怪。 | 亨利·列斐伏尔 晓默(编译) | 2005 | 建筑师2005,,5: | 23 |
| 18 | THE ALEKSANDROV PROBLEM FOR UNIT DISTANCE PRESERVING MAPPING显示文摘In this paper, one of the Aleksandrov problem was resolved, the proof that a mapping f which preserve unit distance between two leaf -normed spaces X and Y is an isometry if Y is a -strictly convex space and f satisfies locally Lipschitz condition was shown, and a same result in normed spaces was given. In addition, a proof which there doesn’t exist any isometry between some spaces was obtained. | 马玉梅 | 2000 | Acta Mathematica Scientia2000,20,3: | 22 |
