This paper aims at the discussion the meanings and essential of urbanization, from the fundamental task of urbanization : spreads city matter civilization and sprit civilization, avoids the city and country duality social frame, improve the level of the people ' s livelihood and production. from these causes, based upon the local color of urbanization, brings forward the thinking of ew garden city framework. and from three points : the town planning, the collectivity planning, the new city design, this paper thinks over, analyses the problem, brings forward the resolve methods
本文旨在通過對城市化內涵、本質的探討，從城市化的根本任務? ?推銷城市物質和精神文明，消除城鄉二元社會結構，實現城鄉人民生產、生活水準質的提高，這樣一些狀態目標出發，立足城市化的地方特徵，提出新田園城市結構模式的構想，並從城鎮體系規劃、總體規劃、城市設計等三個層面加以思考，剖析問題，提出解決的方法。In this work, layered lini1 - xalxo2 ( 0 < x 1 / 2 ) solid solution materials were successfully synthesized by current co - precipitation method in the air, and their preparation and properties were deeply and systematically explored. influences of different factors on the structure and properities of samples were studied, including li resources, different performs, li / m ( oh ) 2 molar ratio, calcining heat condition, the best synthesis technics were concluded : sintered for 16h at 700 from li source ( lithium nitrate ) : m ( oh ) 2 = 1. 05 : 1, ultrasonic vibration for dispersing and catalysing are best. lini0. 8al0. 2o2 exhibited a discharge capacity of 130. 7 mah ? g - 1 in the voltage range of 2. 8 ~ 4. 40v and at a specific current of 0. 2 c. a new co - precipitation method was proposed, it included ultrasonic for dispersing and catalysing, by dropping lioh to the aqueous solution of metal nitrates, hydroxides of metals were precipitated and the resulting solution was evaporated as received
採用傳統共沉澱工藝在空氣氣氛中成功地合成出了二元lini1 - xalxo2 （ 0 < x 1 / 2 ）層狀固溶體系列，綜合考察了不同鋰源、預處理方式、鋰的配比量、焙燒溫度等條件對合成產物的結構和性能的影響，確定出了最佳合成工藝:以硝酸鋰為鋰源，超聲波作為分散動力源，鋰源與鎳鋁金屬鹽摩爾比為1 . 05 : 1 ， 700下焙燒16h的lini0 . 8al0 . 2o2樣品電化學性能最佳，在2 . 8 ~ 4 . 40v之間， 0 . 2c的倍率放電可逆容量達130 . 7mah ? g - 1 。
