Based on the equilibrium equation of an arch element the cubic nonlinear dynamic model with second order is established and the nonlinear differential dynamic system without constant term is obtained through a transfer process of T=U+b. Hence three fixed points and the homoclinic orbits are found. The critical condition of the chaotic vibration of the elastic arch is given by using the method of Melnikov function. The numerical results of the stationary and chaotic motion are given and discussed.

首先利用拱的单元平衡方程建立了拱的二阶三次非线性动力学模型；然后通过变换使方程转化为不含常数项的非线性微分动力系统，并由此得到无扰动系统的3个不动点与同宿轨道；再用Melnikov函数法给出了发生混沌的临界条件；最后给出了该系统出现定常运动和混沌运动的数值结果。

4Based on the analysis above, a local finite element model of the united-arch-feet three-span continuous through type bow-string arch bridge is established and analyzed. The simplification of the external force and the boundary displacement, the internal relation between local analysis and whole analysis, the analytic method of partial nodes are discussed. Suggestion is made for the design and construction of this kind of bridges, insuring the structure safety.

在静力分析的基础上，对三跨连续下承式系杆拱桥的拱脚结合部位进行局部应力分析，探讨了局部节点分析的外力和位移边界条件的简化，局部分析和整体分析的内在联系，局部节点分析的方法等，避免设计的盲目性，对今后此类桥梁的设计、施工提供建设性的意见和建议，确保结构安全。

福鼎新桐山大桥主桥为51m+75m+51m三跨连续的下承式钢管混凝土刚架系杆拱，拱肋采用了新型哑铃型截面。

The story of these stamps began on may 14,1918,the day after they were placed on sale.in washington,d.c.,w.t.robey,a man interested in stamps,decided to buy a sheet of the new stamps and so went to the new york avenue branch post office in washington.when the clerk handed him a sheet of the stamps robey noted that they were poorly centered.he looked at other sheets and found that none was well centered.the clerk asked robey to return later in the day when more stamps were expected.

关于这些邮票的故事发生在1918年5月14日，该日是它们开始销售的第二天。在首都华盛顿，一个集邮爱好者，罗比，决定去买一整版新邮票，于是他来到华盛顿市纽约大街的邮政支局。当职员递给他一版新邮票时，罗比看到它们的中心位置很差。他看了其它几版，没有一个摆正中心位置。职员告诉罗比当天晚些时候来退换，估计那时有更多邮票到货。
