查询词典 three-centered arch

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.

The second part demonstration uses three methods to test the herding and analyses the herding in Chinese stork market by the proper data from June the first, 2005 to June the first 2007, and then uses the investment aggregation intensity model to analyze the fund managers" herding based on the board effect. The conclusion is that the elucidative ability of Shanghai Stork average PE is strong to Herding effect, but the whole equation"s R~2 is small.

它们分别是基于分散度的羊群行为检验，基于CAPM的羊群行为分析和基于ARCH模型的羊群行为分析，得出的结论是：在基于分散度方法进行分析时，排除剧烈羊群行为的可能，但是不排除轻微的羊群行为存在的可能性；基于CAPM和ARCH模型的羊群行为分析中，得出的结论是市场收益率的二次项系数均显著为负，说明中国股票市场存在羊群行为。
