论翻译中的文化依附

文化依附问题在翻译中至关重要。本文用若干有说服力的译例从文化偶合、文化并行、文化冲突、文化空缺四个方面介绍分析了在翻译过程中如何处理文化依附矛盾的问题。     

Sensitivity analysis on responsive pricing and production under imperfect demand updating

This paper examines three types of sensitivity analysis on a firm's responsive pricing and responsive production strategies under imperfect demand updating. Demand has a multiplicative form where the market size updates according to a bivariate normal model. First, we show that both responsive production and responsive pricing resemble the classical pricing newsvendor with posterior demand uncertainty in terms of the optimal performance and first‐stage decision. Second, we show that the performance of responsive production is sensitive to the first‐stage decision, but responsive pricing is insensitive. This suggests that a “posterior rationale” (ie, using the optimal production decision from the classical pricing newsvendor with expected posterior uncertainty) allows a simple and near‐optimal first‐stage production heuristic for responsive pricing. However, responsive production obtains higher expected profits than responsive pricing under certain conditions. This implies that the firm's ability to calculate the first‐stage decision correctly can help determine which responsive strategy to use. Lastly, we find that the firm's performance is not sensitive to the parameter uncertainty coming from the market size, total uncertainty level and information quality, but is sensitive to uncertainty originating from the procurement cost and price‐elasticity.     

高超声速滑翔飞行器滑翔段初始状态的唯一性和最优性分析

临近空间高超声速滑翔飞行器的弹道特性主要受滑翔段初始状态和飞行器控制律影响。在飞行器控制律确定的情况下,研究了滑翔段初始状态对高超声速滑翔飞行器弹道特性的影响规律。按照滑翔弹道的不同形式,在纵向平衡滑翔条件下,通过理论推导得出飞行器状态变量的解析式,结合平衡滑翔条件分析平衡滑翔弹道滑翔段初始状态的唯一性；在纵向跳跃滑翔条件下,构建弹道性能评价指标,利用群智能算法,寻找弹道性能最优时的滑翔段初始状态。利用单因素敏感性分析方法,分别对两种滑翔弹道的滑翔段初始状态进行敏感性分析,初始状态中初始速度对弹道特性的影响最大。对高超声速滑翔飞行器初始状态唯一性与最优性的分析,可为高超声速滑翔飞行器的弹道设计、弹道跟踪、轨迹预测和轨迹优化提供借鉴。     

制导炸弹滚转通道混合灵敏度鲁棒控制器设计

制导炸弹在大空域飞行过程中受到外界干扰和未建模摄动都较大,为了适应较大摄动,采用混合灵敏度方法来设计鲁棒控制器.首先推导了包含S/T/R的广义受控对象的状态空间模型,将混合灵敏度问题化为标准H∞问题.然后针对混合灵敏度问题中如何选取权函数的关键性问题,讨论了权函数选取的一般原则,提出了权函数选取的一般方法,并尝试给出权函数的一般形式.最后采用该方法对制导炸弹滚转通道进行了控制器设计,仿真结果表明:H∞控制器有较好的鲁棒性能,且比传统PID控制有更好的时域性能.

Kernel estimation of quantile sensitivities

Quantiles, also known as value‐at‐risks in the financial industry, are important measures of random performances. Quantile sensitivities provide information on how changes in input parameters affect output quantiles. They are very useful in risk management. In this article, we study the estimation of quantile sensitivities using stochastic simulation. We propose a kernel estimator and prove that it is consistent and asymptotically normally distributed for outputs from both terminating and steady‐state simulations. The theoretical analysis and numerical experiments both show that the kernel estimator is more efficient than the batching estimator of Hong 9 . © 2009 Wiley Periodicals, Inc.

《望大陆》三种英译文初探——兼谈词性转换和意义陈述的运用

汉诗英译有时必须放弃追求形式对等的努力，必须透及深层，把握意义陈述的意念机制，而不是形式机制。这符合奈达最初提出的信息对等，而不是形式对应的翻译概念。本文列举并分析了于右任诗作《望大陆》的三种英译，并强调应该向笔者所提供的试译那样，运用好词性转换和意义陈述的翻译策略。     

基于Sobol’法的歼击机需求影响因素灵敏度分析

针对歼击机需求确定影响因素众多、传统分析方法仅能进行定性分析的问题,提出了基于Sobol’法的歼击机需求影响因素灵敏度分析方法。在构建了歼击机需求确定模型的基础上,提出了基于Sobol’法的歼击机需求确定模型参数灵敏度分析步骤,并结合算例验证了方法的可行性和有效性。分析结果表明:我方拟夺取空中优势等级的概率、敌方出动歼击机的数量和敌我双方歼击机作战效能的比值对歼击机需求的影响较大,战术运用系数、协同作战系数和管理优劣系数的影响微乎其微。
