The relation between out put of simulated pump and heart, and the relation between terminal impedance of model pipe and of equivalent artery have been formulated.
确定了模拟心泵输出与人体心输出间以及模型管的终端阻抗与当量动脉的终端阻抗之间必须依从的关系。

According to the principle of equivalent stiffness, we analyze the stability of the whole pipe, and thereby get a theory formula of the critical load of the whole pipe.
根据刚度等效的原则，将井管整体进行稳定性分析，并得到井管整体稳定性临界荷载的理论计算公式。

IG541 fire suppression laboratory and a equivalent length of pipe fittings measuring system were established.
