A dynamic interaction schematic of an end bearing or elastic bearing pile with arbitrary force at pile top is founded. by using helmholtz resolution and the operator decomposition method, biot ' s equations governing motions of a porous solid saturated with interstitial fluid are decoupled
建立飽和土中端承樁和摩擦樁在任意激振力作用下的理論模型，利用位移勢函數及微分運算元分解方法，得到飽和土層biot動力固結方程的分離變量解。 -
Fluid motions try to reverse the field on a few thousand years timescale, but the solid inner core tries to prevent reversals because the field cannot change ( diffuse ) within the inner core as quickly as in the fluid, outer core
盡管流體運動會在幾千年的時間尺度上使磁場倒轉，但因為磁場的變化（擴散）在內核里不能與在外核的流體中一樣快，所以固體的內核會盡力阻止倒轉。
