Under the joint action of buoyancy, hydrodynamic force and capillary power, oil (gas) moves intermittently. This has been verified in the physical simulation experiment.
在浮力、水动力和毛细管力的共同作用下，油（气）呈间歇性运动，这在物理模拟实验中已得到证实。

Ease of Application - Excessively wide tolerances tend to break capillary force; and, as a result the alloy will either fail to flow throughout the joint or may flush out of the joint.
