意思表示解释对当事人真意的探寻实际上需要通过语义的探究来实现。语用学以语言哲学对意义的思考为滥觞,为意思表示的解释提供了新的视野和方法。依照解释学理论建构的意思表示解释规则,在一定程度上与语用学的意义探究方法相契合,但同时也表现出零散、不系统和立场游移的特点。因而,意思表示解释规则的建构应综合解释学的"解释者—文本"与语用学的"言语—言说者"双重视角,为解释者提供更具操作性的规则。

关键词：语用学意思表示解释规则语境还原当事人立场解释学

Acta Oceanologica Sinica 2009年第4期28卷 107-117页

作者： LIU Yong LIYucheng TENG Bin XIA Zhisheng Key Laboratory of Ocean Engineering Ocean University of China Qingdao 266100 China State Key Laboratory of Coastal and Offshore Engineering Dalian University of Technology Dalian 116024 China Key Laboratory of Water ＆ Water ＆ Sediment Science and Water Hazard Prevention Changsha 410076 China

This study examines the reflection of regular and irregular waves from a partially perforated caisson breakwater located on a step bed. The step bed is treated as an idealized rubble mound foundation. Based on the linear potential theory, an analytical solution is developed to calculate the reflection coefficient of the structure subjected to regular waves. The matched eigenfunction expansion method is used for the solution. The regular wave method is also extended to irregular waves using a linear transfer function. The calculated results obtained for limiting cases are exactly the same as corresponding results given by the previous researchers. The present predictions also agree well with experimental data in the published literatures. Numerical experiments are conducted to examine the variations of the reflection coefficient versus its main effect factors, and some interesting results are presented.

关键词： partially perforated caisson step irregular waves reflection coefficient
