在两个焊接的固体介质边界处,质点速度的三个分量和垂直拉力在通过边界时是连续的。然而,在横穿流体与固体分界面时,只有质点速度的垂直分量是连续的,水平分量可能不连续。此外,流体压力与固体中拉力的垂直分量方向相反,且界面处拉力的水平分量为零。利用后一现象,可根据布置在海底的单分量检波器记录的质点速度的垂直分量计算总 At the two welded solid media boundaries, the three components of the particle velocity and the vertical pull force are continuous across the boundary. However, when crossing the fluid-solid interface, only the vertical component of the particle velocity is continuous and the horizontal component may not be continuous. In addition, the fluid pressure is opposite to the vertical component of the tensile force in the solid, and the horizontal component of the tensile force at the interface is zero. Using the latter phenomenon, the total component velocity can be calculated from the vertical component of the particle velocity recorded by the single-component detector disposed on the seafloor
