The planning of road and traffic in historic block is not only one of presupposition in historic block protection and renovation , but also one method of dulling the traffic contradiction in historic blocks which are located in the city center today 歷史街區(qū)的道路交通規(guī)劃,是歷史街區(qū)保護與整治的前提之一,也是緩解當前位于城市中心的歷史街區(qū)的交通矛盾一種手段。
Along with our country urban economy development and the industrial structure adjustment , also more and more needs to pay great to the economical aspect regarding the old city transformation in historical block protection also question the factor 隨著我國城市經濟發(fā)展和產業(yè)結構的調整,對于舊城改造中的歷史街區(qū)保護也越來越要注重經濟方面的因素,應當有效的將歷史街區(qū)的保護更新與開發(fā)利用相互結合。
By principles of city renaissance , historical block protection , circumference area harmonious development and sustainable development , the layout and design for reconstruction of zhongshan road downtown was done ; the function orientation and development goals of this area was analyzed ; in combination with the practical situation of zhongshan road , seven function subareas were discussed 摘要本著城市復興、歷史街區(qū)保護、周邊地區(qū)協(xié)調發(fā)展、可持續(xù)發(fā)展的原則,進行了中山路商貿區(qū)改造的規(guī)劃設計的研究,分析了中山路地區(qū)功能定位與發(fā)展目標,結合中山路實際情況,闡述了七大功能分區(qū)。
Today with our country urbanization advancement speeds up unceasingly , it is urgent that regarding the historical block protection as research topic , the historical block massively located the old city center position , as a result of geographical position , spatial structure and so on , has the inevitable contradiction and the conflict with the modern city business district development 在我國城市化進程不斷加快的今天,對于城市中的歷史街區(qū)的保護成為迫切需要研究的課題,而大量位于舊城中心位置的歷史街區(qū)由于地理位置、空間結構等原因,與現(xiàn)代城市商業(yè)區(qū)的發(fā)展存在著不可避免的矛盾與沖突。
Has used the induction and the analysis method , in line with investigates the question , found the problem , the analysis question , solved the question work manner , the utilization specialized theory and the design method , sociology , economics knowledge and so on the union plan study has conducted the research and the discussion to the historical block protection method of exploitation 本文采用了歸納和分析的方法,以調查問題、分析問題、解決問題的工作態(tài)度,運用專業(yè)理論和設計方法,結合規(guī)劃學、社會學、經濟學等知識對歷史街區(qū)的保護性開發(fā)與設計的方法及其模式進行了研究與探討。
This paper presents a method that chopping wave is done by switch devices which consist of three - level resistance regulating module and intelligence power module ipm , and which realizes constant - current discharge of storage battery . to achieve the intelligence control of the drive protection and the discharge process of ipm , the paper designs circuit formed by igbt threshold drive pulse pwm signals . ipm fault - blocking protection circuit and microcomputer 80c196 . the devices can accurately control the 0 ~ 150a discharge current and the discharge time of the storage battery and calculate the releasing power 實現(xiàn)蓄電池恒流放電過程智能控制是蓄電池放電裝置發(fā)展的必然趨,本文提出了一種通過三極電阻調節(jié)模塊和由智能功率模塊ipm為開關器件進行斬波從而實現(xiàn)蓄電池恒流放電的方法。為達到對ipm的驅動保護和放電過程的智能控制,文中設計了igbt門極驅動脈沖pwm信號形成電路和ipm故障封鎖保護電路及由單片機80c196為核心的微機控制器。本裝置能夠對蓄電池進行0 150a放電電流及放電時間的精確控制及釋放容量的計算。
The full text altogether divides six main chapters : the first chapter introduction the city business district development and the historical block protection contradiction embarked from the chinese current urbanization advancement , proposed regarding the historical block protective development and design research essential and the importance 全文共分六個主要章節(jié):第一章緒論從中國當前城市化進程中城市商業(yè)區(qū)發(fā)展與歷史街區(qū)保護的矛盾出發(fā),提出了對于歷史街區(qū)保護性開發(fā)與設計研究的必需性和重要性。
