By analysis of frequency spectrum based on matlab platform , wavelet method in the application of cutting out a section of inputting earthquake wave was presented . in the process of pseudo dynamic test results , the method of non - dimensional representation and analytic representation of hysteretic curve was provided . the above two methods will help to compare dissipation energy capacity of this structure at the different acceleration peak value stage of pseudo dynamic test more precisely and comparably 通过基于matlab的地震波频谱分析，说明了小波分析方法在拟动力试西安建筑科技大学博士学位论文验中地震波截取方面的应用；在拟动力分段试验数据的处理方面，本文将试验结果的无纲量表示方法以及曲线的多项式拟合法引入滞回曲线的数据处理，这将有助于拟动力试验不同加速度峰值条件下，各阶段结构耗能能力的客观比较。
Because the relationship between the lift on the fin and the fin angle is gotten by the static hydrodynamic experiment , which has great error , especially dynamic hydrodynamic experiment , the control torque gotten by the experiment can not counteract the wave torque well and the stabilization result is not perfect 而鳍的水动力试验存在着很大的误差，特别是在动态条件下，鳍的水动力特性测试更困难，所以这种通过计算求得控制力矩的方法产生的鳍升力无法很好地抵消波浪力矩，因而影响了减摇效果。
Analysis system for bridge test ( qljc in chinese ) is an application software specially designed for bridge test to build spatial fem model of bridge structure with beam elements or solid elements , analyze the static and dynamic character of bridge structures , calculate efficiency ratio of load test , pick up the results of observation points and so on 摘要桥梁结构检测分析系统qljc是针对桥梁检测试验分析开发的专用软件，能够建立桥梁结构空间有限元模型，运用实体单元法和空间梁格法进行静动力试验分析、试验荷载效率计算，查取测点位置理论计算值等。
