语境作用下的零情态句式

情态意义是指介于肯定与否定之间的意义,它表达的是说话者对某个命题的主观态度和看法。其表达形式往往是在句子中加入情态动词、情态副词和小句等情态成分。但是在语言的实践中,有些形式为肯定或否定的句式却也可以传达情态意义,有学者称之为零情态句式。而对于这样的句式只有语境才能确定其是否表达了情态意义。     

亚波长光栅的零级反射特性研究

从严格耦合波衍射理论出发,在不同入射角、方位角和光栅参数下的情况,计算了矩形亚波长光栅零级反射效率随入射光波长的变化.通过计算结果,找出相对合理的光栅参数,使得当入射光的入射角或方位角发生变化时,光栅反射出不同波段的光,即反射出不同颜色的光.这些研究可应用于防伪技术,为设计和制作防伪光栅提供了设计依据.

关于零翻译的若干问题探讨

本文从翻译的定义、译者作用、语用心理、翻译实践的需求和语用效果等方面论述了零翻译概念引入的必然性和必要性,围绕译界长期争论的焦点问题展开讨论,从理论和实践方面分析了可译性原则与零翻译之间的辩证关系,肯定了零翻译概念的历史、现实意义与实用价值。     

“利率走廊”调控与准备金制度功能的异化

在“利率走廊”调控模式中，存款准备金制度可以被证明能够克服“零准备”的局限，改善“利率走廊”调控中货币需求曲线的形状，平滑中央银行无货币量变动调控的偏差，从而提高利率调控的效果。这给我们带来启示，我国的存款准备金制度不仅不会阻碍我国在条件成熟时实行“利率走廊”调控，甚至还能提高这种调控的效果。     

Case study in data analysis: Variables related to codling moth abundance and the efficacy of the Okanagan Sterile Insect Release Program

The authors consider the effect of orchard attributes and landscape in a heterogeneous area on the efficacy of a control program for the codling moth in apple orchards in British Columbia. The context is first presented, along with a set of questions of importance to the Okanagan Valley Sterile Insect Release program. Two groups of analysts then address a number of these issues using methods for spatial‐temporal data including counts, proportions and Bernoulli variables. The models are then compared and the relevance of the results to this operational program is discussed.

Bayesian confidence interval for difference of the proportions in a 2×2 table with structural zero

This article studies the construction of a Bayesian confidence interval for risk difference in a 2×2 table with structural zero. The exact posterior distribution of the risk difference is derived under the Dirichlet prior distribution, and a tail-based interval is used to construct the Bayesian confidence interval. The frequentist performance of the tail-based interval is investigated and compared with the score-based interval by simulation. Our results show that the tail-based interval at Jeffreys prior performs as well as or better than the score-based confidence interval.
