The results show that the toughness of over-heated zone increased greatly because of austenite film lying in lathy martensite and a few ferrite.The toughness of fine grained zone decreased due to many factors,such as acicular martensite,a small quantity of austenite film,carbide separation and so on.

结果表明，10Ni8CrMoV这一新型钢种的模拟焊接热影响区的过热区和细晶区表现出与绝大多数材料完全相反的规律，过热区存在少量的铁素体组织，马氏体板条束之间形成了一定量的奥氏体薄膜，这些韧度相的存在使得过热区的冲击韧度与基体相比有了较大的提高；细晶区部位奥氏体含量很少，细小的板条马氏体端部呈针状特征造成应力集中，易于诱发裂纹。

The combined bioreactor, which consists of a bacteria zone and a fungi zone, can overcome the shortcoming of the traditional bioreactor. Both hydrophilic and hydrophobic volatile organic compounds and mephitic compounds in the odor gas can be removed effectively by the synergistic reaction of the bacteria and fungi in the combined bioreactor.

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。
