它山之石 可以为错——就苏词编年答保苅佳昭与曾枣庄君

就数首苏轼词编年提出与曾枣庄、保佳昭的不同看法 ,用大量事实考证出《永遇乐·长忆别时》作于宋神宗熙宁八年 (1 0 75 )正月 ,《浣溪沙》二首 (“倾盖相逢胜白头”、“炙手无人傍屋头”)作于熙宁七年 (1 0 74)三月 ,《南歌子》三首 (“雨暗初疑夜”、“日出西山雨”、“带酒冲山雨”)作于宋仁宗嘉八年 (1 0 63 )二月下旬至三月上旬 ,《双荷叶》词题中“湖州贾耘老小妓名双荷叶”之“双荷叶”乃两妓均以荷叶名之而非一妓姓双名荷叶 ,贾耘老也不可能娶双荷叶为妻。

Modeling and Analysis of Vibration Characteristics of Rectangular Plate with Circular Through Hole Under Complex Boundary Conditions

This paper presents a method to study the free vibration of a plate with circular holes.The circular hole is regarded as a virtual small plate in which the mass density and Young's modulus are zero.Therefore,the free vibration problem of the circular hole plate can be transformed into the free vibration problem of the equivalent rectangular plate with non-uniform thickness.The model is derived from the spectral geometry method(SGM),and the displacement of the plate with circular holes is expanded by the modified Fourier series.Virtual springs are added to the boundary of the plate to simulate the boundary conditions of simply supported and fixed supports.The accuracy of this method is verified by comparison with the finite element calculation results.The relationship between modal numerical solutions of plates with circular holes and boundary conditions and geometry of the plate is studied.

岩石孔隙中流体的核磁共振谱研究

岩石孔隙中流体的核磁共振（ＮＭＲ）谱线表现出严重的增宽效应，固液界面性质是原因之一，当孔隙表面含有磁性杂质时，线宽增加会更加明显，模型分析表明，孔隙形状及其排列方式是另一重要因素。两种分子筛、硅胶以及天然砂岩孔隙中吸附或饱和甲苯与戊醇的＾１Ｈ及＾１３ＣＮＭＲ谱提供了依据。由此推断，岩石孔隙中流体的ＮＭＲ谱包含丰富的孔隙结构信息，低速魔角旋转（ＭＡＳ）即能够使岩石中饱和流体的ＮＭＲ谱线有效窄化。

郝敬《五声谱》与现代京山方音

明代郝敬撰写的《五声谱》是一部方言韵书,反映了明代京山方音的某些特点。论文在前贤研究基础之上,梳理历史材料,结合实地方音调查,探讨《五声谱》与现代京山方音的关系。论文提出《五声谱》反映的是明代京山鄢郝一带的方音,与现代京山中片方音一脉相承:存在入声调;梗摄臻摄合口三四等见组、影组、晓组字合流;蟹摄开口三等、合口一等与止摄开口三等部分韵字同音;明母德韵、陌韵、麦韵字同音;遇摄合口一三等与流摄开口一三等齿音字合流;曾摄、梗摄、臻摄、深摄开口三等字合流;臻摄合口一等与曾摄开口一等端组、泥组、精组合流;果摄开口一等与合口一等合流;泥母与来母不分。同时也体现了语音的演进与变化,集中体现在全浊声母的分化、入声韵的归并、蟹摄开口一等二等的分合等方面。
