Based on the analysis of micro -bolometer resistance -temperature characteristics, a new readout circuit was proposed. It allowed micro -bolometer operate without a temperature stabilizer over a wide range of ambient temperature. And it need a Flash memory to store the correcting factors of different temperatures and a temperature sensor to detect the ambient temperature of the micro -bolometer. By utilizing the factors in the Flash memory, Digital Analog Converter controls the micro -bolometer bias current to compensate the fluctuation of ambient temperature.

Beijing environmental problems hold severe, and atmospheric and water pollute, soil and water loss, hot island and yawp are leading problems,and take on territorial characteristic. Based on research on relativity between urban forest and these environmental problems, urban forest can effective improve environmental quality in Beijing. And for the aim of improve environmental quality, Beijing forest overlay should attain 35% at least in citywide range, and local-areas being severe environmental problem should be provided with higher forest overlay.5. Through the study on urban forest needed capacity, Beijing's forest coverage is up to par in citywide range, but montanic forest coverage, plain covered with trees and average forest area are lacking, and CO2 and O2 balance is incapable;form the point of heat and balance CO2 and O2 balance,urban forest the city zone and suburb is lack. There is urban forest developmental potential space,but the city zone and suburb area need be compensated form urban forest in circumjacent region.6. On the based of the above results and ecological network system, the author drived whole region into city area, plain and mountain area are needed at the point of planning thoughts of running-through forests and water .
根据城市森林与北京市主要环境问题的相关性分析,城市森林在改善这些环境问题中具有重要的作用,为有效改善这些环境问题,整个北京市域范围内森林覆盖率至少达到35%,并且分布比较均匀,环境问题严重的局部区域需要不同程度增加森林覆盖率。5、通过对北京市城市森林需求量研究发现,虽然在市域范围内北京森林覆盖率达到了国家标准,但是山区森林覆盖率、平原林木覆盖率、城区人均森林面积不足;从区域热平衡和碳氧平衡角度分析,城区和郊区不能满足本区域的城市森林需求量,虽然北京市城市森林具有一定的发展潜力,整体上基本可以满足城市需要,但是这些区域需要依靠周边区域城市森林的补偿。6、根据以上的研究结果,以中国森林生态网络体系建设的点、线、面布局理念为指导,以&林网化——水网化&作为优化理念,将北京市整个市域划分为城区近郊区及其辐射区域,平原区和山区三大区域,依据三大区域特点进行城市森林布局优化。

In this paper, preliminary FDS fire chamber to simulate the flue gas generated through the corridor adjacent to the room near the migration laws, an analysis of indoor air flow field and the movement of smoke layer, and through the simulation of fire scenes, in a simple form of visual dynamic display of the entire process of fire, in the simulation process to obtain more accurate fire-related parameters such as temperature distribution, gas flow and heat radiation, and analysis of simulation results through the fire chamber of the flue gas migration characteristics, results showed that the chamber in the absence of fire smoke control measures, the process of the spread of smoke filled the first chamber is at the top, with the passage of time, the proliferation of slowly downward until the entire chamber is full, and then through the corridor smoke quickly spread to the nearby chamber.
本文运用FDS初步模拟了腔室火灾产生的烟气通过毗邻的走廊向附近房间迁移的规律,分析了室内空气流场和烟气层运动状况,并通过对火灾场景的模拟,以简单直观的形式动态显示出火灾发生的全过程,在模拟过程中获得较准确的火灾相关参数,如温度场分布,烟气流动及热辐射等,并通过模拟结果分析腔室火灾的烟气迁移特性,结果表明着火腔室在无防排烟措施的情况下,烟气扩散的过程是首先充满腔室顶部,随着时间的推移,慢慢向下扩散,直至将整个腔室充满,然后烟气通过走廊快速向附近腔室蔓延。

According to the relationship between temperature and the focal spot of lens antenna, the focal spot size of homemade millimeter wave dielectric lens antenna was measured by infrared temperature measurement technology. The experimental result, which was regard as the actual value, was achieved through analyses and calculations, and its designed value was corrected with it, then the exact radiation of millimeter wave was achieved.

In 1921-1922 he unveiled his design for a giant urban settlement,"Une ville contem-poraine pour 3 millions d'habitants,"and by 1933 he had further developed his think-ing in La Ville Radiant City.Throughout his career Le Corbusier would offer numerous idealized poetic sketches as solutions to the complicated problems of real urban places such as the South American cities of Rio de janeiro,Sao Paulo, Montevideo, Buenos Aires,and Bogota;the African city of Algiers;and the French provincial cities of La Rochelle and Saint-Die. One of his large urban conceptions-a design for the governmental center of Chandigarh,India-was constructed posthumously.
在1921年至1922年,他推出了自己设计的一个巨大的城市住区&, une市contem - poraine倒三百万-h abitants&,由1 933年进一步发展了,他认为英在洛杉矶市辐射c ity.throughout生涯柯布西耶将提供许多理想化的诗意的写生作为解决这一复杂问题的真正市区的地方,例如南美的城市里约热内卢,圣保罗,蒙得维的亚,布宜诺斯艾利斯和波哥大;非洲城市阿尔及尔和法语省级城市拉罗谢尔和圣死。
