Based on the mechanical equilibrium equation, the state equation of the stochastic structural responses under random loading is deduced. By introducing the augmented state vector, the probability density evolution equation ( PDEE) of the stochastic structural static response is then established. 基于力学平衡方程,导出了随机荷载作用下随机结构反应的状态方程,进而引入扩展状态向量,建立了随机荷载作用下的随机结构静力反应的概率密度演化方程,讨论了其差分数值求解技术。
Firstly, it puts emphasis on how the time interval between trades influences on the equilibrium state and the probability distribution of market orders. 首先,分析交易之间时间间隔对限价指令簿收敛到均衡状态的影响,以及市价指令流的概率分布情况。
