从读者反应理论看朱生豪、梁实秋的莎译本中文化空缺词的翻译

读者接受理论为文学翻译提供了一个更为开放的视角,值得重视和借鉴。然而,如果全盘接受读者接受理论的观点,把文学翻译仅仅看作一种译者主体行为,势必会导致不准确的翻译。读者对于文化空缺词的接受能力是一个历史的动态变化过程。     

Adaptive tests of regression functions via multiscale generalized likelihood ratios

Many applications of nonparametric tests based on curve estimation involve selecting a smoothing parameter. The author proposes an adaptive test that combines several generalized likelihood ratio tests in order to get power performance nearly equal to whichever of the component tests is best. She derives the asymptotic joint distribution of the component tests and that of the proposed test under the null hypothesis. She also develops a simple method of selecting the smoothing parameters for the proposed test and presents two approximate methods for obtaining its P‐value. Finally, she evaluates the proposed test through simulations and illustrates its application to a set of real data.     

用声学测量预报等温淬火球墨铸铁强度

等温淬火球墨铸铁的机械性能与其声学性能相关。本文将两种碳当量球铁在８４５，８９９和９４５℃温度进行奥氏体处理，在２６０，３１６和３７１℃温度进行等温淬火得到证实。声学性能测量包括共振频率，声速和内耗。由共振频率转换成动态模量表示出这种关系可以用来预报球墨铸铁不同热处理条件下的机械性能。     

TESTING SPHERICITY UNDER A MIXTURE MODEL

The robustness of Mauchly's sphericity test criterion when sampling from a mixture of two multivariate normal distributions is studied. The distribution of the sphericity test criterion when the sample covariance matrix has a non-central Wishart density of rank one is derived in terms of Meijer's G-functions; its distribution under the mixture model is then deduced. The robustness is studied by computing actual significance levels of the test under the mixture model using the critical values under the usual normal model.

Some remarks on the physical models concerning two different approaches to inference in statistical process control

Summary For technological applications it can be useful to identify some simple physical mechanisms, which, on the basis of the available knowledge of the production process, may suggest the most appropriate approach to statistical control of the random quantities of interest. For this purpose the notion of rupture point is introduced firstly. A rupture point is characterized bym randomly arising out of control states, assumed to be mutually exclusive and stochastically independent. Shewhart's control charts seem to represent the natural statistical tool for controlling a rupture point; however it is shown that they are fully justified only when the hazard rates attached to the causes of failure are constant. Otherwise, typically in the presence of time increasing hazard rates, Shewhart's control charts should be completed by a preventive intervention rule (preventive maintenance). In the second place, the notion of dynamic instability point is introduced, which is specifically characterized by assuming that the random quantity of interest is ruled by a stochastic differential equation with constant coefficients. By discretization, developed according to a possibly new approach, it is shown that the former model reduces to an equation error model, which is among the simplest used in adaptive control, and thus particularly easy to deal with in regard to parameter estimation and the definition of the optimum control rule.     

基于顾客资源的动态竞争优势

随着市场竞争环境变化的加剧,企业战略竞争的基点正在从企业内部的资源转移到企业适应外部环境的动态能力上,顾客资源因能有效地衔接企业内部资源和外部环境机会而成为弥足珍贵的战略性资源,以顾客资源为基础构筑的核心竞争力正日益体现出强大的动态竞争优势。因此,企业只有通过加快转变企业的战略管理理念、重构企业内部的业务流程、改革传统的价值链模式和实施企业的顾客忠诚化管理等途径构筑基于顾客资源的动态竞争优势,才能将企业立于竞争的不败之地。     

斜腿刚构桥几何布局的优化设计

采用数学规划的方法从静力和动力两方面对斜腿刚构桥的几何布局进行优化设计。静力优化设计的优化目标是截面截面应力平方均值最小，动力优化设计的优化目标是结构自振周期平方和最小。采用了直接搜索法寻优。通过算例可知，这两种优化设计方法均可行，且均为刚性设计。

论大学英语水平统一测试的优越性

我国现行有两套考试系统用以测试大学英语水平:大学英语46、级考试(CET-4/6)用来衡量非英语专业学生的英语水平,而英语专业48、级(TEM-4/8)考试则用来测评英语专业学生的英语水平。依据Bachman和Palmer语言测试原则,为了保证语言测试的有效性,语言测试任务应该与语言应用任务相对应,这种对应是语言测试的出发点和目的。既然如此,对于非母语的中国大学生而言,就没有必要以英语专业或非英语专业的区分用不同的测试来区分他们的英语水平。从这一点出发,完全可以将现行测试非英语专业学生CET-4/6和测试英语专业学生的TEM-4/8合二为一。问卷调查分析也表明,实行全国大学英语统一测试比分成两套考试系统的英语测试更具优越性。
