Abstract:
利用格结构下的不动点定理,研究了一类测度链上动力方程的两点边值问题\"\" (1) 其中\"\", ,T是[0,1] 上的闭集, \"\"\"\"连续,且\"\" 。文中结合相应算子的特征值,在非线性项满足次线性条件下,得到此边值问题具有正解,负解和变号解。
In this paper, by using the fixed point theorems with lattice structure, we discuss the existence of multiple solutions for the following second-point boundary value problems of dynamics equation on a general time scale.\"\" (1) where \"\" , Let T be a closed subset of the interval[0,1]? , with\"\" , and the function\"\" is continuous, with \"\" . Combining the eigenvalues of the relevant linear operator, the existence of positive, negative and sign-changing solutions is obtained under the condition that the nonlinear term is sublinear.
论《失乐园》中亚当的正当理性与选择
On Adam’s right reason and choosing in Paradise Lost


- , 2015, DOI: 1672-3104(2015)01-0204-07
Abstract: 摘 要: 在《失乐园》中,亚当的正当理性与选择涉及弥尔顿的古典资源与神学思想之间的复杂关系。通过区分自然法与实在法,可以说明正当理性与选择之间并无抵牾。上帝赋予亚当自然法,使其可以遵从正当理性。但是有关知识树果子的命令属于实在法,与正当理性不自动相合,因此亚当才有了真正意义上的选择。《失乐园》中自由选择(free choice)与真正的自由(true liberty)之间实有差异:前者对应亚当自由选择的能力,后者则是他遵从正当理性的结果。亚当在吃知识树的果子时,行使了自由选择,但他选择的是夏娃,而非遵守上帝的命令。这一事件的后果之一便是正当理性被蒙蔽,亚当从此失去了真正的自由。
Abstract: In Paradise Lost, Adam’s right reason and choosing involves the complex relation between Milton’s classical thoughts and theological ideas. The article, by distinguishing positive law from the law of nature, contends that right reason and choosing are not contradictory. God implants the law of nature in Adam to teach him things agreeable to right reason, while God’s command about the Tree of Knowledge belongs to the positive law which is not intrinsically in accordance with right reason. Thus, Adam can make a choice in the real sense. Moreover, the free choice (or freedom to choose) should be distinguished from true liberty in the epic. The former refers to the ability of free choosing, whereas the latter denotes the outcome of choosing in accordance with right reason. In tasting the Fruit of the Tree of Knowledge, Adam exercises his freedom to choose, yet what he has chosen is Eve rather than obeying God’s command. One of the consequences of this event is the privation of the right reason and Adam henceforth loses his true liberty

生物物理学报 , 2006,
Abstract: 小雪节气刚过,噩耗传来,中国科学院院士、国际著名生物化学家邹承鲁先生永远离开了我们。中国乃至世界失去了一位睿智、正直而伟大的科学家,但恩师引领我们走入科学殿堂的谆谆教导却永远铭记在我们的心中。随着“文革”后科学、教育事业的恢复,作为“文革”后第一届研究生(78级
Erceg伪度量连续性公理及其基本球的关系的研究
The Researches of the Continuous Axiom of Erceg’s Pseudo-Metric and the Relationships between Its Basic Spheres

Advances in Applied Mathematics (AAM) , 2015, DOI: 10.12677/AAM.2015.42026
Abstract:
该文通过对Erceg-Peng公理与经典度量公理进行比较,证明了它的诱导拓扑与Erceg-Peng度量公理的连续性条件没有本质的联系,并且还进一步给出Erceg-Peng的一些基本球之间的一些相互关系。
In this paper, by comparing the axioms of Erceg-Peng metric and classical metric, we have proved that there is no intrinsic relationship between the topology induced by Erceg metric and the con-tinuous condition in its axioms, and further given some relationships of several types of basic spheres in Erceg-Peng’s pseudo-metric.

运用主成分分析识别道路网中的网格模式

武汉大学学报(信息科学版) , 2013,
Abstract: ?提出了基于主成分分析的网格模式识别方法。首先利用形状参量和关系参量描述道路网中的网眼;然后生成网眼数据的主成分;最后,根据主成分分析构造参量权重的思想,导出网眼属于网格模式隶属度,根据该参数识别网格模式。实验结果表明,识别结果与肉眼识别类似。
运用q统计分析网络空间现象关联模式

武汉大学学报(信息科学版) , 2014,
Abstract: ?目的空间关联模式的分析和发现是空间数据挖掘领域关注的热点问题。介绍了q统计的概念,并将距离测度定义为网络最短路径。应用q统计对一种网络空间现象———酒店的空间关联模式进行了分析。研究结果从空间数据挖掘的角度验证了酒店间的聚集效应。同时,也说明了q统计在进行网络空间现象关联模式分析中是有效的。最后对欧式空间与网络空间下的q统计进行了比较。
