There are three platinum catalyst micro channels which have different width ,such as 1000 m , 400m and 40m. The platinum catalyst micro channel reactor is fabricated by MEMS technology. The reactor uses the exothermic reaction of hydrogen and oxygen on the platinum catalyst plate as the heat source and the platinum thin film resistance deposited on a glass chip by face micro machining process as catalyst and temperature sensor. The channel is bonded with a cover plate etched by bulk micromachining technology to become a mico- channel reactor.

实验主要以微机电加工技术制作白金触媒微管道反应系统，利用微机电面型加工技术将白金薄膜电阻制作於基材为玻璃的晶片上，以此为反应所需的触媒及温度量测元件，并用体型加工技术蚀刻出微流道的上盖板相结合成微管道反应系统，本研究以1000μm、400μm及40μm的白金触媒微管进行测试，并利用微管道管壁上触媒表面降低反应活化能的特性来维持反应，此微反应系统利用氢气与氧气在白金触媒平板上的放热反应作为能量的来源。

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。

Malaysian Tzu Chi volunteers from the Wellesley Province cities of Butterworth, Bukit Mertajam, Nibong Tebal and Bukit Tambun, recently convened a large-scale vegetarian charity bazaar to raise funding for Tzu Chi's medical, charity and educational missions. With around 200 booths, 1,500 volunteers came to lend a helping hand. Among them were one couple, who, after attending last year's fair, were each deeply stirred by the volunteers' selfless work, and so returned this time to participate in the event by selling pasta to help raise money for the needy.

马来西亚威省的北海、大山脚、高渊和武吉淡汶四地的慈济志工，合力举办了大型素食义卖会，来筹募慈善、医疗、教育基金，义卖会总计有200个摊位，大约1500位的志工来付出，其中有一对夫妻，去年参加义卖会后，看到慈济人付出不求回报，内心相当感动，因此加入慈济，这一次义卖会他们承担义大利面，希望能帮助更多的人。
