查询词典 counterchange

In general, there is lots of geographic information on it. Point symbols, linear symbols, area symbols and texts counterchange on topographic map. Description of Relations among graphs is very difficult. Besides, there is defectiveness in scanning and deformation of map.

从总体上看，地形图承载了大量的地理信息，各种点状符号、线状符号、面状符号、文字注记在空间上纵横交错、相互叠置，反映在地形图上的是图形目标间的关系难以描述，再加扫描技术的不完善等因素，这给图象的分割和要素的识别以及拓扑信息的提取带来了很大的困难。

The dissertation gives a omnifarious textual research into Jiujiang"s economy from the all and the one of Jiujiang and the drainage areas of Yangtse River ,synthetically using the methods of history , intercity science , economics , geography and sociology .This dissertation also goes deep into the conventional function and the switchover of its neoteric role,demonstrating the bidirectional nexus between the inland areas of Jiangxi and Yangtse"s entrepot,based on the angle of the center of Jiujiang"s economic noumenon. It probes into the vicissitude from center to verge in the aspect of Jiujiang"s trade. Eventually This dissertation opens out the incompleteness in the course of the neoteric switchover ,based upon the pectination of Jiujiang"s neoteric switchover in the aspects of economic counterchange , urbanoid development and thesocial flux.This dissertation thoroughly delves the typologic significance of Jiujiang"s economic noumenon in the course of the modern switchover of Chinese cities.

全文综合运用历史学、城市学、经济学、社会学等有关理论和方法，将九江与其所处的江西腹地和长江流域作为一个整体进行了多方位的考察，深入探讨了九江社会的传统功能与近代角色的转换；论证了九江以内外贸易为纽带，与江西内腹地区以及长江贸易中心城市之间互补互动的双向关系；剖析了九江从中心到边缘的变换历程；最后，以九江城市为基点，从经济转型、城市发展、城市社会变迁等方面对九江近代社会的转型进行梳理，揭示了九江近代转型不完整性这一基本特征，进而探讨了九江在中国城市近代转型中所具有的类型学意义。
