基于电子海图平台的气象信息处理主要是将气象信息数据以图形的形式显示在电子海图平台上.这样必须把气象信息数据的地理坐标转换为与电子海图相一致的投影坐标。电子海图的投影坐标主要是墨卡托投影坐标。因此文章重点探讨了如何将气象信息因子数据的原始地理坐标转换为与电子海图的墨卡托投影坐标相互匹配。  相似文献

为探寻更为科学的内河航标分级方法,提出以航标效能为标准对内河航标进行分级的构想.首先,借鉴海上交通安全评价方法,建立内河航标效能评价层次结构,并利用层次分析法计算各层次指标权重.其次,运用模糊综合评价法构建内河航标效能评价模型,初步探索基于航标效能的内河航标分级标准.最后,探讨基于分级理论的航标配布优化方法和分级管理模式.该方法能有效地弥补航标配布过程中暴露的某些缺陷,优化航标配布体系,提高航标管理效率,进而提高内河航标助航服务质量.  相似文献

随着船舶自动识别系统(Automatic Identification System,AIS)和电子海图信息与显示系统(Electronic Chart Displayand Information System,ECDIS)的出现及普及,使船舶交通管理系统(Ves-sel Traffic Service,VTS)对其辖区的航行船舶进行自动搁浅预警成为可能.针对预警自动化水平较低这一现状,提出搁浅预警(Search Area for Grounding A lert,SAGA)模型,通过判断船舶SAGA领域内最小水深是否满足安全要求来实现船舶搁浅预警.  相似文献

Since the late 1960s,culture has been considered tighter with communication.Culture IS based on the community of communication.Communication involves people and their environment.Thus culture is an important factor in communication.Today with modem economic and technological development,intercultural communication is mole important than ever before. When people from different cultural background communicate with each other,their social stereotype pattern of behavior, their habits of language and thought differ from one another,because these are the possible factors that affect intercultural communications.Culture norms also change,culture may be transferred as signs but we have to study and understand the above carefially.  相似文献

The thesis mainly discusses the character of the heroine in Charlotte Brontes famous novel "Jane Eyre". There are three major parts-introduction,analysis which is the main body of the thesis,and conclusion.Jane Eyre,the heroine,is a new woman image who requires independence equality and freedom.The thesis just analyzes Janes these rebellious characters through four peroods of her experiences.First,in her childhood,she has shown her rebellious spirit.As an orphan,Jane suffers a lot of misery.Not only her aunt treats her cruelly,her cousins despise her,but also do servants have a prejudice against her.In Janes immature heart, she is unwilling to bear ill treatment.She rebels them bravely.Second,when she studies at Lowood,her rebellious spirit is exposed furtherly.Her view doest stay in Mrs Reeds,instead turns to the whole society.She makes hypocrisy of so-called charity to be discovered completely.At the same time,she declares her independent,equal rebellious thought to her friend-Helldn who endures oppression willingly.Third,she,as a governess in Thornfield Hall falls in love with Rochester-her master.During this period,her thought grows into maturity.Thought she loves him passionately,she never loses her dignity and independence for him.When she knows his mad wife still lives,she makes up her mind to leave him.For she doesnt want to become his mistress.Fourth,her refusal of St Johns proposal of marriage depicts Janes character.She knows John does not love her at all and his purpose of marriage is only to perform his great task missionary.Jane does want to become a sacrifice.She breaks traditional morality,then she goes back to Rochester.  相似文献

The context of a word consists of the other words surrounding it and the situation in which it is used.When we come across a new word in our reading,instead of looking it up in a dictionary for its definition,we can guess its meaning from its context.  相似文献

"Midnight"is a poem written by Archibald·Lampman,a Canadian poet,who loved nature very much,but his poor health prevents him from being very active in the outdoor life.So he is often the quite,thoughtful observer of nature in his poems.This article mainly talks about how to appreciate the poem in the following aspects:word selecting,rhyme,sentence structure and atmosphere.After reading this poem,we cannot get rid of the air of horror and mystery."Midnight" reveals another aspect of the nature:wild,rough and unknown.There is something else in the nature that can awe human beings even though we don't know what it is.  相似文献

当代中国武术经历了时代的沧桑和变迁,在历经了文化和历史的发展与洗礼之后,依然发展、繁衍至今。在这样一个漫长的过程中,伴随着以社会环境和社会人群价值取向为主的变迁与变化,当代中国武术的发展与当代社会的发展正逐渐的呈现出某些相背离和不和谐的表象。通过研究,我们发觉中国武术中原本一些内在的东西正在不断的被遗忘,正在不断的流逝。本文试从中国武术在当代发展中的问题境域入手,解读中国武术在当今世界和社会中存在的一些问题,希望能够从中找到中国武术发展的"合法性"或"合时性"的内在依据,以挺立中国武术的脊梁。  相似文献
