麦茨"八大组合段"理论的读解与批判

电影符号学理论的产生是电影理论进入现代阶段的标志.麦茨的"八大组合段"理论是第一个也是迄今为止仅有的一个基本可行的合理的切分模式,而这种合理的切分又是对影片进行科学的精细化的分析批判必不可少的.其明显的局限在于割裂和回避了电影形式和内容的关系等实质问题,是一种纯描述性的理论体系.     

马克思主义与中国实际相结合的伟大产儿

中国近代向西方学习的不断深入 ,为马克思主义在中国的传播创造了思想条件和阶级条件 ;为先进的中国人找到了正确的社会理想 ;为如何学习西方 ,包括学习马克思主义找到了方法论的启示 ,即实事求是。从而得出结论 :中国共产党的创立 ,是马克思主义与中国实际相结合的伟大产儿。     

Estimation in proportional hazard and log-linear models

Proportional hazard models and models where the dependent variables follow a linear model are shown to be equivalent if and only if the hazard rate is the product of a non-negative periodic function and a Weibull factor. Estimates based on rank statistics are proposed for the parameters in the proportional hazard model.     

Inference for step-stress accelerated life tests

In this paper we consider the more realistic aspect of accelerated life testing wherein the stress on an unfailed item is allowed to increase at a preassigned test time. Such tests are known as step-stress tests. Our approach is nonparametric in that we do not make any assumptions about the underlying distribution of life lengths. We introduce a model for step-stress testing which is based on the ideas of shock models and of wear processes. This model unifies and generalizes two previously proposed models for step-stress testing. We propose an estimator for the life distribution under use conditions stress and show that this estimator is strongly consistent.     

The use of metaevaluation to plan evaluations of conservation programs

The U.S. Department of Energy (DOE) is sponsoring and will be required to evaluate a wide range of conservation programs. The development of evaluation plans for such programs can often be improved by reviewing evaluations that have been done on similar programs. The Residential Conservation Service (RCS), sponsored by DOE, is discussed as an example of how conducting metaevaluations can improve evaluation planning. Many utilities have sponsored programs that are similar to the RCS. A review of the utility program evaluations suggested key methodological issues and data problems that should be considered in the development of an RCS evaluation plan. The implications of these metaevaluation findings for an RCS evaluation plan are discussed.     

“X 就是 X”构式研究

本文从构式角度分析“X就是X”这一结构。它表示说话者对谈论对象强调性的确认与肯定,但说话者的个人情感和主观倾向则需要结合具体语境去体会。但是,所有这些意思不能单单通过构成“X就是X”这一结构的成分的形式或意义体现出来,因此具有不可预测性和整体性特征。此外,对构成“X就是X”结构中的“X”的组成成分进行分析,并对“就是”的分解与其表达的意义展开讨论。     

从配价理论看“N1是AV的N2”结构的歧义生成

从以往研究中可以发现,“N1是AV的N2”结构有些时候会存在歧义现象。以配价理论为基础,论证这类句子歧义的生成大多是由两种原因造成：一种是由于中心动词和与其共现的配价名词之间出现了复杂的语义关系;另一种是由于中心动词和隐省的配价名词之间出现了复杂的语义关系。     

超薄N6镍板焊接焊缝成形质量研究

当镍及镍基合金板材厚度小于l mm时,在焊接过程中容易出现烧穿、气孔和裂纹等缺陷,严重影响了焊接成形 质量。针对超薄镍及镍基合金的特殊性以及在焊接过程中易出现的问题,采用脉冲微束等离子弧方法焊接0.1 mm厚薄 镍板。文中分析了在一定占空比下,不同脉冲频率和不同基脉比对超薄N6镍板的焊缝成形质量的影响,得到合适的焊 接工艺参数。研究结果表明当基脉比为0.4,脉冲频率为500 Hz时,超薄N6板焊缝成形质量最好。通过该研究成功实 现了0.1 mm厚超薄N6的脉冲微束等离子弧焊接。
