Advances in Psychology (AP) , 2013, DOI: 10.12677/AP.2013.34025
Abstract: 目的:初步探索大学生自恋的因子结构,区分阴性自恋和阳性自恋。方法:自编大学生自恋问卷,采用随机抽样的方法,以北京林业大学260名本科生为样本进行研究。结果:1) 通过探索性因素分析,阳性自恋由权力欲望、自我中心(需求)、自我关注构成,阴性自恋由敏感脆弱、自我孤立和贬低他人构成,共解释总变异的59.512%2) 问卷各个因子的内部一致性系数在0.618~0.812之间,且各因子与自恋问卷总分基本达到中等偏高的显著相关,相关系数在0.382~0.861之间(P < 0. 01)3) 阴性自恋和阳性自恋分别与积极情绪总分存在显著相关(r = 0.257, 0.222, P < 0. 01),阴性自恋与消极情绪总分存在显著正相关(r = 0.340P < 0. 01)

Objective: To develop a questionnaire to evaluate the homesickness of Chinese college students, and then test its reliability and validity. Methods: Literature review, observation and interview were used to compile an initial questionnaire. According to the standardized process of questionnaire preparation, about 730 college students were recruited as research subjects. Then the obtained data were analyzed by item analysis, exploratory factor analysis, confirmatory factor analysis, reliability tests and validity tests. The final questionnaire structure is established finally. Results: The formal questionnaire includes 18 questions forming three dimensions: emotional connection, contact frequency and hometown preference. The cumulative variance contribution rate was 56.65%. The questionnaire has good structural validity. The alpha reliability of the total questionnaire is 0.90; the alpha reliability of three factors is between 0.78 and 0.87; the split-half reliability of the total questionnaire is 0.84; the split-half reliability of three factors is between 0.79 and 0.88; the retest reliability of the total questionnaire is 0.77; and the retest reliability of three factors is between 0. 66 and 0. 72. Conclusion: The questionnaire developed in this study is well-structured, reliable and valid, and it can be used as an effective tool to assess Chinese college students’ homesickness.

完美主义者对不完美图形的注意偏好研究
,周晓林,刘兴华4,潘苗苗5
心理科学 , 2011,
Abstract: 本研究通过两组点探测任务实验,考察高完美主义者和低完美主义者对不完美图形的注意模式。两组实验都表明,当不完美图形与完美图形成对出现时,高完美主义的个体倾向于回避不完美图形,而低完美主义的个体对不完美图形表现出一定的注意倾向。图形不完美的程度对被试的注意偏好模式也有影响。被试比较容易从对中度不完美图形的注意中抽离出来。研究者推断不完美图形能够唤起完美主义者的“不完美焦虑”,产生注意俘获效应,使其比非完美主义者更难从对这类图形的注意中抽离。

内积空间与最小二乘法
Inner Product Space and the Least Square Method
 [PDF]


Pure Mathematics (PM) , 2013, DOI: 10.12677/PM.2013.31011
Abstract:
最小二乘法在一般的线性代数中存在标准的推导过程。本文从内积空间的结构出发去发现最小二乘法的本质问题,并且给出了最小二乘法取值的快速算法。同时我们给出了在内积空间中多个点到子空间的最小距离的求法,这是对一般最小二乘的延托。The least square method has a standard method in most of books about linear algebra. In this paper we introduce the element definitions of inner product space and the standard least square method. And in this document we also give a fast calculation for the least square method in inner product space. In the least part we give a method for calculating the smallest distance of the sum of finite points to a subspace. This is an extension for the least square method.
强化污泥厌氧消化性能的预处理技术研究进展
Progress in the Pretreatment of Sludge Anaerobic Digestion
 [PDF]


Sustainable Development (SD) , 2016, DOI: 10.12677/SD.2016.63017
Abstract:
随着我国城市污水处理厂污水处理量的逐年增加,剩余污泥产量也日益增大,导致其处理处置难。污泥因为其含水率高、富含有机质及病原体,在处理处置之前,必须进行稳定化处理。厌氧消化是污泥稳定化的常用技术,特别是针对大中型污水处理厂,并且可以通过产甲烷,实现能源回收。但由于细胞壁的存在,使得污泥水解成为厌氧消化的重要限速步骤。通过一定的预处理作用,可有效地提高细胞壁的破解效率,促进胞内有机物的溶出,大幅缩短污泥厌氧消化周期,提高污泥厌氧消化性能。本文综述了污泥厌氧消化预处理的各种主要技术的优缺点,包括生物处理、热水解、机械处理、化学氧化处理和碱处理等技术。目前研究的重点主要集中在预处理后污泥的性质变化及产甲烷性能的改善方面。
With the increase of wastewater treatment capacity of wastewater treatment plant in China, the production of excess sludge is increasing day by day, leading to the difficulty in treatment and disposal. The sludge must be stabilized before final disposal because of its high moisture content and rich in organic matter and pathogens. Anaerobic digestion is a common technology for sludge stabilization, especially for large and medium sized wastewater treatment plants, and can be used for production of methane to achieve energy recovery. However, because of the presence of the cell wall, the hydrolysis of sludge is key limited step of anaerobic digestion rate. The pretreatment technologies of sludge can effectively enhance the damage of the cell wall, promoting the intracel-lular organic matter releasing into aqueous phase, improving the sludge anaerobic digestion per-formance. The advantages and disadvantages of various pretreatment technologies of sludge an-aerobic digestion were reviewed in this study, including biological treatment, thermal hydrolysis, mechanical treatment, chemical oxidation treatment and alkali treatment. At present, the research focuses on the characteristics of the sludge after pretreatment and the improvement of methane production.
