大到太空中的飞船,小到一瓶矿泉水,容器的密封都是很重要的.但理论模型对阐明密封器是如何泄漏的过程并不清晰.众所周知,最为大家所熟悉的密封圈是用橡胶制作的,它处于两个接触面之间,加大了固体表面-橡胶圈-底座间的接触面积,使彼此靠得非常紧密.尽管如此,容器中的液体或气体仍然会泄漏出来.因为各种界面相对来说都是比较粗糙的,无法达到完全的接触.如果表面上的缝隙网络能在两接触面的边界间提供一条通道,则泄漏必将产生.为了能估计沿着两界面之间的缝隙与接触面的分布状态,需要建立一些 Large spacecraft, as small as a bottle of mineral water, the container seal is very important.But the theoretical model to clarify how the seal is leaked process is not clear.As we all know, the most familiar seal is the use of Rubber, it is between the two contact surfaces, increasing the contact area between the solid surface - the rubber ring - the base, so that they are in close contact with each other. However, the liquid or gas in the container can still leak out because All kinds of interfaces are relatively rough and can not reach complete contact.If the surface of the gap network can provide a channel between the two contact surface, then the leak will be generated in order to be able to estimate along the two interfaces Between the gap and contact surface distribution, need to establish some
