The stiffness of the long floating bridge and the propagation velocityofdisplacement wave are much less than those of the general steel or concrete bridge.
浮桥的抗弯刚度和受弯变形位移波的传播速度都比一般钢桥或混凝土桥小得多。

Third, in order to calculate microscopic sweep efficiency in pore models, we define sweep boundary ofdisplacement fluid, and determine it by velocity method.
