旅游产业发展的灰色关联分析——以黑龙江省为例
Grey Correlation Analysis of the Development of Tourism Industry———Taking Heilongjiang Province as an Example
 [PDF]


Business and Globalization (BGlo) , 2013, DOI: 10.12677/BGlo.2013.12005
Abstract:
旅游产业被誉为21世纪的朝阳产业,是现代服务业的龙头产业。旅游产业的发展涉及到旅行、游览、住宿、饮食、购物、娱乐等6个环节,要找到发展的重点才能更好的促进旅游产业的进步。本文运用灰色关联分析方法,以黑龙江省为例,充分结合2002~2011年的数据,研究旅行社、旅游饭店、旅游交通对于旅游产业的关联性。研究表明:旅游饭店与旅游产业的关联性最强,其次是旅游社,旅游交通的关联性最弱。因此应该重点发展旅游饭店,然后提高旅游社的发展,最后是对旅游交通进行投资,期望通过本文的研究对黑龙江旅游产业发展提供借鉴。
Tourism industry is known as the 21st century sunrise industry, and is the leading industry of modern service industry. The development of the tourism industry involves six aspects: travel, tour, accommodation, food, shopping, entertainment and so on, and we need to find the focus of the development to better promote the progress of the tourism industry. Taking Heilongjiang province as an example, and combining with the data of 2002-2011, the relevance of travel agencies, tourist hotel, tourism traffic and tourism industry is researched. The result shows: the tourist hotel and tourism industry’s relevance is the strongest, then the travel agency, and tour transport is the weakest. So we should focus on the development of tourist hotel, then improve the development of travel agency, and finally invest in tourism traffic. We hope this study could provide reference for the development of tourism industry in Heilongjiang.

Abstract: 社会比较是指个体把自己与具有类似情境的人比较,进而作出评估的过程。本研究采用社会比较特点问卷对204名大学生进行现状调查。结果表明,1) 大学生被试的社会比较特点从总体上看属于中间状态,且相对积极;2) 大学生被试社会比较特点中的参照性、易比性和突出性在年级上存在显著差异,大四被试的参照性显著低于其他三个年级,大四的易比性平均分显著低于大一和大二;大一的突出性平均分高于大三和大四;3) 大学生被试的社会比较特点各因子及总均分不存在性别差异;4) 不同生源地的大学生被试的社会比较特点各因子及总均分均无显著性差异,即大学生社会比较不受其生源地因素的影响。
Social comparison refers to a process that individuals compare themselves with others at the sim-ilar situations, and then make assessment. In present study, 204 college students were investigated using the Characteristics of College Students’ Social Comparison Questionnaire. The results showed that: 1) the social comparison of the whole objects is in the middle state, and relatively positive; 2) the reference, comparison disposition, and prominence in the process of the social comparison have significant difference in grades. The seniors’ average scores on the reference are much lower than the other three grades; as to the comparison disposition, the seniors’ average scores are lower than the freshmen and sophomore significantly; about the prominence, the freshmen have higher average scores than juniors and seniors differently; 3) there is no significantly difference on gender during the process of subjects’ social comparison; 4) the students from rural areas have no great difference with the ones from city on the six dimensions and the whole condition of the social comparison processing, meaning that college students’ social comparison is not influenced by the places that students come from.
儿童执行功能研究方法评述
A Introduction on Research Methods of Children’s Executive Function
 [PDF]

Advances in Psychology (AP) , 2015, DOI: 10.12677/AP.2015.58063
Abstract: 儿童执行功能的研究一直受到国内外研究者的关注,目前在发展心理学中所用到的研究方法也很多,但并不是所有的方法都适用于儿童。因此,本文根据儿童发展的心理特点分冷热执行功能就儿童的执行功能的研究方法进行介绍。通过这些方法的介绍来帮助更多的研究者对儿童执行功能的发展有个更清晰的认识。同时,也为儿童执行功能的发展提供理论和实践参考。
Children’s executive function research has attracted researchers’ attention both at home and abroad. The methods have been used in developmental psychology so much, but not all of the me-thods are suitable for children. Therefore, this article is based on the psychological characteristics of child development points on the children’s cool and hot executive function. The introduction of these methods can help more and more researchers to understand the development of children’s executive function clearly. At the same time, it can also provide theoretical and practical reference for children’s executive function.
Riemann面——平面上的空间结构
Riemann Surface—3-Dimension Construction on a Plane
 [PDF]

Pure Mathematics (PM) , 2014, DOI: 10.12677/PM.2014.42010
Abstract:
Riemann面是复变函数课程中的一个很有特色的内容,也是学生学习中的一个难点。本文从代数和几何这两个视度,简单分析了Riemann面的作用。文中的描述,试图简单、直观、易懂,为初学者了解Riemann面,提供点滴直接的帮助。
Riemann surface is a characteristic content in the course of complex variable function, which is also a difficult point in teaching. Our paper, viewing the problem from both algebra and geometry, simply analyses the action of the Riemann surface. The description here is as simple and directive as possible. By this way, we wish that could provide a little help to the beginner.
台资跨境生产网络的空间重组——电脑企业从珠三角到长三角的转移

地理学报 , 2011, DOI: 10.11821/xb201110005
Abstract: 基于从全球生产网络(GPNs)层面分析区域发展战略性耦合(strategiccoupling)的视角,本文探讨自21世纪初以来,台资跨境生产网络在中国大陆的空间重组,特别是个人电脑(计算机)企业从珠三角向长三角地区再布局的动力机制与格局。通过对相关企业的深度访谈与个案研究,指出台资个人电脑企业在珠三角地区与长三角地区的空间再布局是在各区域地方制度下,GPNs架构中全球领先企业(globalleadfirms)与分布在2个三角洲区域处于GPNs较低层级供应企业(supplierfirms)之间进行不同的战略性耦合之结果。研究阐明在经济全球化背景下‘新区域主义’理论对区域发展仅分析区域内部因素之局限性,因应跨地域(trans-local)动力的出现,全球生产网络视角下区域内部与外部因素的战略耦合,已成为理解全球经济化下区域发展的重要理论框架。
用于环氧树脂固化监测的自参考型光纤固化传感器

复合材料学报 , 2001,
Abstract: 研究了一种新型的自参考型光纤固化传感器,用于环氧树脂固化过程的实时监测。用光纤芯折射率为1.558的多模光纤制成端面反射型折射率传感器,利用环氧树脂的折射率与固化度之间的对应关系,通过实时测量环氧树脂的折射率进行固化监测。在固化过程中,当环氧树脂的折射率变化到与光纤芯的折射率相等时,传感界面的反射信号为零,传感器可对零点偏置和灵敏系数进行校准,在此后的固化过程中,传感器能够定量地测量环氧树脂的固化度。在用多个传感器对树脂内不同部位的固化过程同时进行监测的场合,各传感器经实时自参考校准后,可根据各自的灵敏系数对输出信号统一定标,从而可以相互比较,实时地反映不同部位的固化反应过程之间的差异。

明清时期田土买卖中的找价回赎纠纷及其解决

法学研究 , 2011,
Abstract: 明清时期民间田土买卖盛行找价回赎之风,围绕着找价遭到拒绝或多次找价,在新旧业主之间引发了大量的纠纷乃至诉讼。依据徽州契约和州县官员办案手记等资料,可以看到田土找赎习俗和纠纷形成的原因,明清朝廷、地方官员及民间百姓针对找赎习俗的不同态度及州县官员解决找赎纠纷的依据和方式。虽然民间找赎习俗与国家律例之间存在着矛盾和冲突,但明清朝廷因时制宜,不断调整有关律例,地方官员在执法中灵活变通,充分考虑当地民情,这使得田土交易秩序得以稳定。
