Through solving the blood flow equations for local vessel expansion region, the analytical expressions of blood flow velocity, pressure and wall shear stress were then obtained.
接着，通过求解局部扩张血管段内的血液流动方程，导得血液流速、压力和血管壁切应力的分析表达式。

As the basic safe wall of nuclear reactor, the reactor pressurevessel not only bears high temperature and high pressure, but also contains radioactive working substance.
反应堆压力容器作为反应堆的基本安全屏障，承受高温、高压且内部包含具有放射性的工作介质。

The Pascal's law is: Seals up intensity of pressure change which in vessel's fluid at rest's some part occurs, will not lose the transmission to the fluid each part and the vesselwall.
