 龚坚刚, 林洲游, 许杨勇, 赵深 Smart Grid (SG) , 2014, DOI: 10.12677/SG.2014.45029 Abstract: 本文建立了考虑电感效应和火花效应的等效接地体时变模型，搭建了特高压输电线路雷击仿真计算模型，来分析土壤电阻率对雷击特高压杆塔顶端时塔顶电位的影响规律。结果表明：当土壤电阻率较小时，塔顶电位随土壤电阻率增加而增加的速度较大，而当电阻率较大时，塔顶电位升高的比较平缓。应根据土壤电阻率情况做防雷设计。This paper established the equivalent model of the inductance effect and the spark effect of the grounding connector when attacked by lightning current. Meanwhile, the article explored the lightning simulation calculation model of the ultra-high voltage transmission lines, and analyzed the influence between the resistance rate and the tower potential when hit by lightning. The result indicates that: when the resistance rate of the soil is less, the tower potential increases greatly with the increase of the resistance rate; and when the resistance rate of the soil is bigger, it increases gently. So it is necessary to design the lightning protection based on the resistance rate of the soil.
 Pure Mathematics (PM) , 2014, DOI: 10.12677/PM.2014.41005 Abstract: 交错级数是数学分析的重点和难点，主要内容包括交错级数的收敛定理和证明过程。本文主要讨论交错级数的重排和数列之间的关系，通过给出数列的几乎单调性的定义来探究一个已收敛的交错级数在何种条件下重排之后依然收敛，并且给出相关证明。Alternating series is a focal and difficult point in the mathematical analysis. It mainly includes the convergence theorems and the certification process. This paper focuses on discussing the relationships between the rearrangement and the alternating series. Through the definition of almost monotonicity of series, the study explores in what conditions that a convergent alternating series still be convergent when it is rear- ranged, and gives relevant proof.
 Pure Mathematics (PM) , 2016, DOI: 10.12677/PM.2016.61009 Abstract: 本文主要证明了一类分数阶非线性微分方程解的存在性和唯一性。文中用到的微分算子是Caputo分数阶微分算子。因这类方程的可解性是与一类Volterra型的积分方程的可解性等价，所以我们主要研究了与之等价的积分方程解的存在性和唯一性。我们通过Schauder不动点定理证明了积分方程解的存在性，用压缩映象原理证明了解的唯一性。 We prove existence and uniqueness of the solution of a nonlinear differential equation of fractional order. The differential operator is the Caputo fractional derivative. For the solvability of the equation is equivalent to a class of Volterra integral equation, we study the existence and uniqueness of the integral equation. We prove the existence of the solution of integral equation by Schau- der fixed point theorem and the uniqueness of the solution by contraction mapping principle.
 游林 电子学报 , 2008, Abstract: 除子标量乘是超椭圆曲线密码体制中的关键运算.基于单除子标量乘的思想,将Duursma与Sakurai给出的关于奇素数域上一类特殊超椭圆曲线上的一个除子标量乘算法推广到奇素数域扩域上更一般的此类超椭圆曲线上,得到了两个效率更高的公式化的除子标量乘新算法.这两算法所需的运算量比二元法降低12%以上.
 Advances in Education (AE) , 2016, DOI: 10.12677/AE.2016.61007 Abstract: 本文从海南陵水黎族自治县的五所中学课堂教学实际出发，通过发放问卷，从教材的处理、课堂提问、课堂讨论以及对练习处理等方面入手，分析教师在教学过程中如何处理学生在学习上的主体性，是否最大化的健全促进学生的全面发展，开放课堂，培养学生的创新能力。 Based on the classroom teaching practice of five middle schools from Li’s autonomous county in Hainan Lingshui, the paper mainly analyzes how teachers handle students’ subjectivity in their studies during the teaching process, whether their teaching gets the maximal promotion of stu-dents’ overall development and whether they have their classroom open, aiming to cultivate stu-dents’ creativity in terms of questionnaire surveys concerning teaching material processing, classroom questioning, classroom discussion and exercise processing.
 Statistics and Applications (SA) , 2013, DOI: 10.12677/SA.2013.21004 Abstract: 本文利用纵横面数据(Panel Data)欲探讨资产配置与保险配置对于资产报酬率及损失率之回归分析。首先，本文以各观察值之资产报酬率及损失率为分群变量，利用集群分析将研究样本区分为两集群的观察值，并对两集群的观察值进行主成分分析建立其资产配置与保险配置之模型，最后藉由纵横面数据分析较适当之回归模型，观察资产与保险配置对资产报酬率及损失率之影响因素。研究结果发现资产报酬率较适用随机效果模型，损失率较适用固定效果模型。再者，资产配置与保险配置间存有交互影响，而不同集群的观察值与资产配置及保险配置也存有交互影响，且影响资产报酬率及损失率之变项也有差异。By collecting Panel Data, this study investigates how life insurance company’s asset and insurance allocations affect asset returns and loss ratio. First, the asset returns and loss ratio of each life insurance company each year are treated as response variables and cluster analysis is used to grouping the companies into observations of two groups. Then principle component analysis is applied to construct the model of asset and insurance allocations of observations of two groups. Finally, find the effects of asset and insurance allocations on asset of returns and loss ratio by regression model for panel data. The findings show that ROA is applicable to the random model and the loss ratio is applicable to the fixed effect model. Furthermore, there exist the interaction effects between asset allocation and insurance allocation. The two groups of companies also exist interaction effects on asset and insurance allocation. Finally, there exist different asset and insurance allocation effect on asset returns and loss ratio.

 游佩林 武汉理工大学学报 , 1995, Abstract: ？本文叙述了确定带电绝缘体表面电荷分布的新方法，给出了绝缘体圆板的电位分布，推导出表面电荷服从指数分布的公式。通过ｐｖｃ与ｐｔｆｅ两类材料的实验证明，这一理论与实验结果符合很好。
 游正林 社会学研究 , 1992, Abstract: 作者通过对农村妇女远嫁的渠道、形成机制、婚后生活状况及远嫁现象的社会影响等问题的系统调查研究,作出如下判断:改革开放拉开了地区间的发展差距,地区间的障碍因素的弱化与人们的思想观念的更新,共同促进了农村妇女远嫁现象的发展。因此农村妇女大批远嫁可以说是改革开放的必然结果。外来妇女对环境有很强的适应能力,对生活的满意度普遍较高。远嫁现象的社会影响复杂且深远,利弊并存,但利大于弊。
