However, due to the large differences in economic development, social operation model, political system and cultural customs etc., there are many pecularities in China. We can see from the two following aspects: one is our the selection of pension institutions which possesses more character of "institutional dependency", and the determinative role of the evolvement of the pension structure on the choice of pension risk management mode can\'t directly be embodied, but the determinative role of the financial structure on overall the pension structure registers as the restriction of our financial system to the development of our private pension plans; the other one is that the magistral situation and product structure of traditional financial institutions, especially insurers, reflect our financial system is not quick to manage pension risk.

然而，由于我国在经济发展水平、社会运行模式、政治制度体制、社会文化习俗等方面与OECD国家存在较大的差异，我国养老金结构与金融结构的相关性也具有一定的特殊性，这种特殊性体现在两个方面：一是我国公共养老金计划主导的养老金制度选择更具有"制度依赖性"，并不能直接地、自然而然地体现出养老金结构演变对养老风险管理模式的决定作用，而金融结构对养老金整体结构的决定作用则更多地表现为金融系统对我国私营养老金计划发展的掣肘；二是我国传统金融机构特别是人寿保险公司在私营养老金计划中的主导地位和产品结构反映出我国金融体系管理养老风险的整体能力还不理想。

On the basis of the improved structure and under the premise of meeting specification requirement, the light steel door-truss structure is optimally designed by changing, cycle checking and gradually reducing the cross section size of overall structural member with the ANSYS parametric design language.

本文研究表明，上部结构的刚度比及隔震层的刚度和阻尼比对结构的局部变形有着很大影响，通过橡胶垫的合理布置，调整隔震层的刚度和阻尼分布，能有效的减小结构的局部变形，提高结构的整体性，从而使隔震效果得以确保；本文的具体结论是，当上部结构的侧移刚度比与隔震垫刚度比一致或相近时，隔震结构的局部变形最小；适当减小子结构的隔震层阻尼比可减小该子结构的局部变形。
