类型电影与观众态度

根据电影叙事是否依据一个形式惯例传统,电影理论把电影分为类型电影和非类型电影。事实上,来自于既有惯例的类型经验影响着我们从日常生活到艺术欣赏很多行为中所具有的心理模式,我们的相关态度在很大程度上也以此建立。本文讨论的是在观看类型电影的时候观众的欣赏态度,并将这个态度分为"作为基础的惯例经验"、"欣赏时建构的心理时空"和"态度的娱乐指向"三个部分,从中可以看到三个部分的相互关系和观众欣赏类型电影的心理特征。     

载波相位平滑GPS伪码伪距的研究

分析了全球定位系统接收机可获取的观测量。给出了载波相位平滑伪码伪距的一个递归算法结构。讨论了平滑算法初值的设定和构造伪距前向预测值，并对各种情况进行了统计分析。文中还给出了平滑算法的性能评估，结论表明载波相位平滑技术可大大改善伪距观测精度。改善程度与该算法中的权重因子和递归时间密切相关     

试论宗教对话的层次性、基本中介与普遍模式——三论21世纪基督宗教的对话形态

宗教对话不仅是一个关乎当代人类文明健康发展的大问题 ,而且还是一个关乎当代宗教和平乃至当代和平的大问题。为此 ,我们从学理上阐述宗教对话的层次性、基本中介和普遍模式 ,以及揭露希克宗教多元主义的要害在于宗教对话的“平面化”。     

语气词在俄语口语中的结构功能

俄语传统语法历来认为语气词不充当句子成分,不发挥任何句法作用.然而,这种特性在口语中却发生了变化;有为数不少的语气词具有结构功能,在交际中发挥着极为重要的作用,这点在语气词研究中往往被忽视.受口语超语言特征的影响,语气词可以充当固定句位句素构成各种结构模式,表达各种情态意义.语气词发挥的结构功能主要有三大类:充当独立语句功能、充当语句结构要素功能及构成对话重复语句功能.     

BNT系纳米粉体的制备及微波特性研究

使用柠檬酸盐法成功制备出分散良好的颗粒状BNT系纳米粉体。经TEM和XRD分析,粉体的平均粒径约30 nm,其主晶相为Nd2Ti2O7,经1 300℃烧结成瓷后还出现了BaNd2Ti4O12相。此类材料具有良好的高频特性,用此类材料研制出的单片微波陶瓷电容器具有良好的微波特性。     

On the logic of common belief and common knowledge

The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge — whether individual or common — is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought — onlymonotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the infinitary nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they aredecidable in the logician's sense.     

Modal non‐linear regression in the presence of Laplace measurement error

In this paper, we propose a robust estimation procedure for a class of non‐linear regression models when the covariates are contaminated with Laplace measurement error, aiming at constructing an estimation procedure for the regression parameters which are less affected by the possible outliers, and heavy‐tailed underlying distribution, as well as reducing the bias introduced by the measurement error. Starting with the modal regression procedure developed for the measurement error‐free case, a non‐trivial modification is made so that the modified version can effectively correct the potential bias caused by measurement error. Large sample properties of the proposed estimate, such as the convergence rate and the asymptotic normality, are thoroughly investigated. A simulation study and real data application are conducted to illustrate the satisfying finite sample performance of the proposed estimation procedure.     

现代汉语语气词意义主观性的主体差异--以《雷雨》为例

文章旨在探讨说话人在使用现代汉语语气词表达主观意义时的主体差异。研究表明:表达主观意义的语言手段多种多样,说话人为了实现交际目的需对其进行选择,这种语言选择会受到各种主客观因素和话语功能的影响。文章尝试以语言主观性为理论基础, 建立现代汉语语气词意义主观性的分析模式,然后对《雷雨》中语气词意义主观性的主体差异进行了个案分析。      

基于ANSYS的行李车改造成发电车的车架设计与分析

现代设计方法的发展和使用,使铁路车辆设计变得越来越快速高效。在行李车改造为发电车过程中,首先根据车架结构对车厢进行布局设计,其次运用有限元分析软件ANSYS对改造后的车辆车架系统从强度和刚度方面进行计算和分析。然后根据分析结果,使用APDL语言对车架薄弱环节和不合理结构进行改进。最后,对改造后车架进行模态分析和谐响应分析,确定有害频率和振型,并采取有效减振措施。从研究结果看,改造后的车辆车架能达到安全使用的设计目的。     

英语学术论文中的遁言研究

学术论文写作并非是不受作者主观影响的就事论事的客观陈述,成功的学术英语写作需要借助遁言运用以达到特定的交际目的.对遁言的运用和分布的研究结果表明:遁言是学术语篇社团成员广泛使用的一种修辞手段,学术英语中的遁言现象不仅是作者、读者、语篇三者交互的结果,也是用语言形式体现作者心理取向的产物,是一种认知情态.遁言研究对学术英语具有重要意义.
