that phase change can increase the nominal stress and the critical internal pressure of vesselsto a great extent.

本文利用二相粒子可提高陶瓷断裂韧性的特点，将其用于电瓷材料高压容器，理论计算结果表明，相变将会使容器的标称应力和极限内压大大提高。

Around the nominal model stable,the control algorithm is proposed based on the Lyapunov function approach and the feasible solution of the linear matrix inequalities.

针对网络控制系统中存在的不确定时延,在传感器采用时间驱动,执行器与控制器采用事件驱动、时延小于一个采样周期的条件下,将网络控制系统建模为一类具有不确定性的线性离散系统并且其标称模型可控。
