对称Levy乘性噪声下平均首次逃逸时问题的计算分析
A Computational Analysis for First Mean Exit Time under Symmetrical Levy Multiplicative Noise
 [PDF]


Advances in Applied Mathematics (AAM) , 2013, DOI: 10.12677/AAM.2013.24018
Abstract:
复杂的动力系统常常受到非高斯的随机扰动。首次逃离现象,即从一个状态空间的有界区域中逃逸出来,对动力系统的随机演化有很大的影响。在本文中,我通过计算分析了在乘性Levy噪声下的首次逃离时问题。一个数值的方法去求解这个非局部的问题,计算分析出不同的跳测度系数和值对系统的首次逃离时间的影响。
>Complex dynamical systems are often subject to non-Gaussian random fluctuations. The exit phe- nomenon, i.e., escaping from a bounded domain in state space, has a great impact on the stochastic evolution of such dynamical systems. In the present paper, the author analyzes mean exit time for arbitrary noise inten- sity under multiplicative noise, via numerical investigation. A numerical approach for solving this non-local problem is proposed. A computational analysis is conducted to investigate the relative importance of jump measure coefficient and the effect of value on first exit time.

Abstract:
对系数均为有理函数的Riccati微分方程,我们在某些特殊条件下,给出了其亚纯解的增长级,极点收敛指数,零点收敛指数和不动点收敛指数的精确估计。
For the meromorphic solution of differential Riccati equations whose coefficients are all rational functions, we give sharp estimates of the order of growth of it, and the exponents of convergence of the zeros, poles and fixed points of it for certain special cases.
4~6岁儿童合作行为认知发展特点的研究

心里发展与教育 , 2004,
Abstract: 采用访谈法对119名4~6岁儿童合作行为认知的发展特点进行了研究。结果表明:(1)幼儿的合作选择认知已经达到了较高水平,其中超过一半的幼儿知道在面对问题时可以与同伴合作解决,而在日常游戏中知道与同伴合作共玩的幼儿更是超过了3.4;(2)幼儿的合作归因主要以结果归因为主,客观条件归因次之;同时,在结果归因中,幼儿主要以个体或活动归因为主,同伴关系和共同利益归因所占比例都相对较少;规则和权威归因在幼儿中仍有一定存在;(3)随着年龄的增长,幼儿合作选择认知和合作归因的水平都不断提高;(4)情境是影响幼儿合作选择认知与合作归因的一个重要因素。

基督教与谭嗣同“仁–通–平等”的政治伦理理念
The Christian-Religion and Tan Si-Tong’s Political Ethics Concept of “Benevolence-Generality-Equality”
 [PDF]


Advances in Social Sciences (ASS) , 2016, DOI: 10.12677/ASS.2016.52040
Abstract:
近代以来,基督教再次传入中国,深刻影响了中国知识分子看待人生的方式。谭嗣同三十岁前后接触基督教,从基督教思想中吸收了很多观念,对他的政治理想起了很大的影响。谭嗣同从基督教思想中引入“以太”、“灵魂”等概念,加深了对“仁”的思想阐发,引入“博爱”与“平等”观念,形成了“仁–通–平等”的政治伦理理念。“仁”即仁爱,是无私无欲的崇高境界,这是他政治伦理思想的核心内容。“通”是“仁”的第一要义,由“通”即中外通、上下通、男女内外通、人我通达到“平等”,包括政治平等、经济平等,社会平等等方面,最终实现“仁”的无私无欲境界。
In modern times, Christian-Religion is re-introduced to China and deeply influences the Chinese intellectuals’ thoughts about life. Tan Si-tong contacted with Christian-Religion around thirty, ab-sorbing a lot of ideas from Christianity, which had great influence on his political ideal. Tan Si-tong introduced the “ether” and “soul” concepts in the Christian-Religion, and deepened the thoughts of “benevolence” based on that. Besides, he introduced the concept of “universal love” and “equality”, and formed the “benevolence-generality-equality” political ethics concept. “Benevolence” means selfless love and realm with no desire, which is the core content of his political ethics thought. “Generality” is the first factor of “benevolence”. Through “Generality” (including Chinese and foreign communication, men and women communication, and interpersonal relationship) people can achieve “equality” (including political equality, economic equality, social equality and so on), and finally realize the realm of “Benevolence”.
关于完全π-正则半群分块定义的一个注记
A Note on the Definitions of Blocks of Epigroups
 [PDF]

Pure Mathematics (PM) , 2016, DOI: 10.12677/PM.2016.62013
Abstract:
完全π-正则半群是其所含任意元的某个幂属于其最大子群的半群。论文给出了两个不同形式的半群分块的定义,证明当所给半群为完全π-正则半群时这两个定义是等价的。论文还提供了分块的第三个定义,证明当分块为子半群时,完全π-正则半群的第三个分块定义与前两者等价。
A semigroup is called an epigroup if for any element in this semigroup some power of the element lies in the maximal subgroup of the given semigroup. In this paper two variants of definitions of blocks of semigroups are given and we prove that two of them turn out to coincide in the case of epigroups. We also offer the third definition of blocks of epigroups and show that if blocks of epi-groups are subsemigroups, then this definition is equivalent to the other two.
