简介：摘要幽默会话借助语言手段来表现幽默诙谐之处。指示语在幽默会话产生过程中起着不可忽视用。从语义学的角度,指示语大体可以分为人称指示语、时间指示语和地点指示语三大类别。同时指示语的意义很大程度上就要依赖于它所使用的语境，离开语境指示语的意义将很难推导。本文意旨从人称指示语的角度分析会话幽默效果的产生。

简介：该研究以功能语法的人际功能为理论框架,汲取语用学中关于人称视点的选择至少受两条语用原则的支配:亲疏原则和地位原则,考察了人称指示视点的选择在《京华烟云》中说话者在给予信息时所使用的命题形式之间的关系,经分析表明,人称指示视点的选择正是命题形式强化言语角色分配及其相应的命题形式反映出具体交际情景中的人际关系的一种努力。

简介：摘要消防应急照明是民用建筑中不可缺少的重要消防设施，民用建筑中地下室因其特殊的地位和重要用途，其消防应急照明系统及其应急疏散指示的设置要求和规范作用不容忽视。本文从消防应急照明系统的组成、应急灯、疏散灯的设置以及应急照明施工与管理的角度深入探讨分析，希望能够给类似工程项目提供一些借鉴。

简介：目前全国各地已有三百万人左右参加速成识字学习，干部很积极，群众很热情，在有准备有步骤地进行这一工作的地方，确实使许多丁部群众突击识了很多字，收到了一定的成效。但也有不少同志没有把扫盲看作是长期艰巨的任务，没有明确认识它必须有周密的准备，特别是师资的准备，才能着手，否则便会产生轻率冒进，便会搞乱。

简介：本项研究的目的是，评估把AlliumcepaL．用作生物指示剂并利用煅烧采煤废物处理酸胜矿山排水（AMD）的效率。在利用煅烧采煤废物处理酸性矿山排水前后，测定其pH值和铝、铁、锰、锌、铜、铅和硫酸盐的浓度。把AlliumcepaL．用作阴性对照物（NC）并暴露于未处理和处理过的AMD及矿水中。

简介：本文通过XRF和ICP-MS测试方法对油页岩样品进行测试,根据常量元素和微量元素特征、组分含量及某些元素的比值,探讨了研究区油页岩样品的地球化学特征,进一步阐述了其沉积环境的指示意义。结果表明,P和B元素强烈富集,相当硼及古盐度值都表明属于半咸水沉积环境,B/Ga、Sr/Ba值也说明受到海水影响或间歇性受海水影响,沉积环境以半咸水湖泊为主;Fe2＋/Fe3＋、V/（V＋Ni）、V/Ni、Cu/Zn、Ni/Co和U/Th值及Ni的含量说明沉积环境为咸化的弱还原-还原环境;Mn/Fe和Mn/Ti值也较小,反映近岸的沉积环境;Sr/Cu表明主力油页岩形成时期处于温湿-干热气候。总体上反映出,研究区油页岩的沉积介质环境的显著特征是半咸水状态的弱还原-还原环境。
