Chapter Ⅶ Harmonious Development Mechanism and Management Pattern Formation of Urban System in Central Shaanxi Plain Firstly, three different view layers of macro, medium, and micro are adopted to study the relevant mechanism for developing urban system in Central Shaanxi; The macro layer mainly probed into the affect from government affair to urban development, reached the conclusion that whether government will rationalize and benefit the harmonious development will be largely owed to the government affair regulation and adaptive general planning system to fix on the urban construction aims and stresses on the foundation of speeding up mechanism and principle innovation; The medium emphasized analyzing the Industry assembling mechanism for harmonious development acceleration and regional distribution and cross-regional adjustment among economic zones from the two aspects of Industry structuring and regional economic spatial location; The micro analyzed the behavioral characteristics of the micro subject and its motivation effects in the urban system development from aspects of enterprises, non-governmental organizations and the public, and set up the compatible mechanism of its active stimulus and restriction.

本章首先从宏观、中观和微观三个层面入手研究了推进关中城镇体系协调发展的相关机制：（1）宏观层面重点研究了政府行为对关中城镇体系发展的影响，认为在不同制度环境下地方政府行为选择也是对其它主体行为选择的理性反应，但地方政府行为能否趋于理性化并有利于关中城镇体系的协调发展，关键还是在于尽快完成关中体制创新和制度创新的基础上，规范政府行为，建立有助于地区利益协调的宏观调控体系，并以此为基点确定了关中城镇体系的宏观调控目标与重点；（2）中观层面重点从产业组织和区域经济空间组织两个方面分析了推进关中城镇体系协调发展的产业聚集机制和各城市经济区的区内组织及区际协调机制；（3）微观层面从企业、非政府组织和公众三个方面入手。分析了微观主体的行为特征及其参与关中城镇体系协调发展的积极作用，并建立了促进微观主体主动参与的激励—约束相容机制。

Using high frequency induction brazing and TiZrNiCu filler metal, the shear strengths of the joints were low. The maximum shear strengh was only 102.1MPa, which was lower than the maximum strength of vacuum brazing. The reasons may be that excessive intermetallics, holes and oxidation existed in the joint. So TiZrNiCu filler metal isn't fit for non-vacuum brazing.The stress variation, stress distribution and crack-sensitive regions during the cooling process of brazing have been studied by Marc non-linear software.

采用气体保护高频感应加热、TiZrNiCu钎料钎焊时，接头的强度普遍偏低，最高的剪切强度只有102.1MPa，远远低于辐射加热真空钎焊的强度，其原因是接头中局部生成了过量的金属间化合物，且产生氧化，接头中含有较多的气孔等影响了接头强度，因此可以认为TiZrNiCu钎料不适合在非真空条件下的钎焊。
