Carbonization is one of the main methods for comprehensive utilization of bituminous coal. Bituminous coal and its solid products from carbonization, namely char and coke, have complex pore structures, which can be characterized by fractals. We performed a study on the fractal structure of the solid products prepared from the bituminous coal of Shuiyu mine in Shanxi Province, China, at different carbonization temperatures (25°C~1000°C) by synchrotron radiation small-angle X-ray scattering (SAXS). The results show that the bituminous coal has a surface fractal structure during the whole carbonization process. The variation of fractal dimension with carbonization temperature illustrates the different stages of the carbonization process. 相似文献

记忆的顿悟优势效应指, 与加工非顿悟问题相比, 加工顿悟问题能够产生更优的记忆保持量。该效应在顿悟的两种操作性定义以及不同实验材料中稳定出现。基于顿悟阶段观, 研究者提出两种理论解释记忆的顿悟优势效应的认知机制:认知的生成效应和表征转化理论认为, 顿悟加工过程中的认知努力、适当迁移加工以及顿悟的表征转换加工促进记忆的保持效果; 情绪的“啊哈”体验理论认为, 加工顿悟问题后的情绪对后续的信息提取具有促进作用。未来的研究可从优化顿悟的指标、巩固记忆的顿悟优势效应、评估其持续性以及更加系统探讨记忆的顿悟优势效应的认知机制等四个方面展开。 相似文献

A person's impression of another depends upon three sources of variance. The characteristics of the target, the characteristics of the perceiver, and the interplay between the two. Researchers have dedicated different amounts of study to these three sources of variance, and therefore they differ in how well they are understood. The present work will first review the portions of the face impression process that are understood well, then identify and discuss portions of the process less well understood. We will then question to what extent the current state of knowledge will generalize to novel targets and populations. Finally, we will review several modeling approaches that can accommodate relatively unexamined yet important sources of variance in impression formation, suggesting a clear path forward toward a comprehensive understanding of face impressions. 相似文献

A mental health evaluation project was conducted in the City of Rio de Janeiro for the entire population of young children who received services in public child daycare centers and preschools. The Brazilian Portuguese version of the Ages & Stages Questionnaires: Social-Emotional (ASQ:SE-BR) served as an outcome measure for social-emotional development. Four age intervals of the ASQ:SE-BR were investigated by time period, 2011 and 2012. A total of 76,806 children from 21 to 66?months were evaluated. Three thousand children were randomly selected from each age interval and year for the analyses. The analyses used unidimensional Rasch Partial Credit Model and multidimensional Rasch Partial Credit Model to evaluate the psychometric properties of the ASQ:SE-BR. The model comparisons indicated support for the one-construct model and the two-construct model, indicating adequate evidence for the internal structure for the ASQ:SE-BR. Only one item was found to have misfit. Sound psychometric properties were supported by the results including internal structure, weighted item fit, reliability, and invariance across years. Item difficulty presented an appropriate coverage across intervals. This study provides supportive evidence for the use and interpretation of ASQ:SE scores with urban low-income Brazilian population. 相似文献

Same meaning but different feelings: Different expressions influence satisfaction in social comparisons

The same social comparison information may be expressed in different ways (e.g. ‘I am better than him’ versus ‘he is worse than me’). The results of four studies indicated that the way social comparison is expressed can affect an individual's satisfaction (i.e. ‘better’ versus ‘worse’). Specifically, in upward comparisons, the expression ‘I am worse than him’ makes individuals feel less satisfied than the expression ‘he is better than me’. In downward comparisons, those who use the expression ‘I am better than him’ are more satisfied than those who use the expression ‘he is worse than me’. The motivation of information processing acted as the mediator. 相似文献

为了明确义符对归纳推理影响,本研究使用有义符和无义符汉字为材料,使用ERP技术考查义符对不同层级类别概念归纳推理的影响。行为结果显示,有义符条件下反应速度更快,肯定判断率更高。脑电指标上,P3阶段义符主效应显著,有义符条件下P3波幅更大;N1、N400和P600阶段义符与层级交互作用显著,组内简单效应分析显示,层级主效应仅在无义符条件下显著;组间简单效应分析显示,义符主效在N400和P600阶段仅在下-上推理条件下显著,无义符条件下,下-上推理引发更大的N400和P600波幅。这些结果表明,义符促进了归纳推理过程,这种促进主要表现在对下-上推理的促进。 相似文献

以大学生为被试,考察因果信息在不同贝叶斯推理问题中的作用。结果表明:(1)问题情境的主效应显著(F(1,122)=16.33,p0.05,η~2=0.120),因果信息的主效应不显著((F(1,122)=1.161,p=0.283,η~2=0.01),但问题类型和因果信息的交互作用显著(F(1,122)=4.757,p0.05,η~2=0.038)。(2)不同类型的问题上因果信息的作用是不同的。具体表现为,在乳癌问题中,增加了因果信息,被试的正确率明显提高(χ~2(1)=6.759,p0.05,V=0.607),而在中彩问题中没有因果信息的推理成绩反而更好(χ~2(1)=1.864,p=0.221,V=0.167)。 相似文献

明末高僧蕅益智旭的著作文集<灵峰宗论>,乃由其门人成时法师负责编辑而成.近百年来,印光法师和今人释宗舜先后发现了成时法师有妄自删改其师著作文字的事实,并对删改问题作了初步的探究.在前人的基础上,本文又结合一些新发现的材料来探讨删改问题.本文先以<宗论>被妄改的事实为基础,为质疑<灵峰蕅益大师自传>(置于<宗论>卷首)一文的真伪问题提供了三大依据,后又以<周易禅解>序跋文本在<宗论>本中如何被删改作为典型例证,结合智旭单行本著作内容与<宗论>本的比较,具体分析成时编选和删改<宗论>的一系列特点,证明<宗论>虽然已被成时删改,但仍具有一定的可信度.本文还意在告诫学界:如果借助<灵峰宗论>来研究智旭及其相关问题,一定要小心谨慎其中文字材料的真伪! 相似文献

思想史的"两重性"探求及意义衍生--李锦全先生对中国思想史本质的诠释 总被引:2,自引:0,他引:2
思想史的“两重性”是李锦全先生关注的焦点问题。文章通过考察他对思想史进行个案研究、学派分析、整体通观三个层次的翔实分析,探求他贯穿在对象研究中的“哲史融会”的方法取向和“承传创新”的文化立场,揭示他以传统观照现代的实践品格,把学术与社会紧密结合的学人精神。 相似文献
