汉英词典例证不足略观

词典是学习者学习外语、查阅资料中必不可少的工具，为读者提供充足的例证来理解并表达准确的含意。词典例证具有 很重要的功能，包括反映基本语义信息、反映概念信息、反映文化信息、规范英语、指导写作等方面，但是例证不足也会给读者 带来很大误导。以姚小平《汉英词典》第三版为例，从例证与释义的衔接不当、例证语体信息的不明确、例证不足及例证译文的 不准确四方面具体分析，重点结合百科知识，对比研究汉英词典中例证的不足之处，以期为汉英词典的例证准确性做出微薄贡 献。     

Accuracy of Numerical Solutions Using the Euler Equation Residuals

This paper is concerned with asymptotic properties on the accuracy of numerical solutions. It is shown that the approximation error of the policy function is of the same order of magnitude as the size of the Euler equation residuals. Moreover, for bounding this approximation error the most relevant parameters are the discount factor and the curvature of the return function. These findings provide theoretical foundations for the construction of tests to assess the performance of alternative computational methods.
