Besides the tacitness, the characteristics also composes of distribution, transferability and appropriabilitry. Based on these foundation, the dissertation explain the existence of the firm as institution for the organization of production, explore the nature of coordination within the firm, analyze organizational structure, focusing upon the implications of the knowledge-based view for hierarchy and location of decision-making authority and determine the boundaries of the firm. In making the comparison, a key distinction is made between the theory of knowledge -based of firm and the theory of transaction cost , which is the main stream theory at present. For one thing, The theory of TC does not take tacit knowledge into consideration, to some degree, but focuses much on the risk of opportunism.

据此，本文对企业理论所关注的企业的存在、企业的协调、企业的组织结构、企业的边界、企业的异质性等问题逐一进行了回答，比如，在企业知识理论看来，企业是一种将个人知识一体化的制度；企业的协调不仅是组织成员目标不一致而产生的需要，而且考虑到默会知识的存在，即使组织成员目标一致，协调仍是必要的；企业之所以具有异质性，其根本原因在于默会知识的难以模仿以及企业在生产过程中形成和积聚的知识的差异性，从而导致各个企业最终所积聚的知识和能力具有差异性。

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, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.
