通过此算法，能计算出抽油杆柱在任意时刻，任意截面的位移和载荷，而且该方法在计算时无条件稳定，特别适用于对斜井的预测。

By using this method, it can evaluate the displacement and the load of any section at any time, and the method is stable, and it is especial adapt to the inclined well.

该法能在一张散斑图上记录下物体动态变形的全过程，在全场滤波时可得到任意时刻的瞬态位移偏导数场。

The whole dynamic process can be recorded on a single specklegram, and the derivatives of displacements of every moment can be obtained by whole-field filtering.

The answer was: at any time t, the location of the particle is given by this formula.

答案是,在任意时刻 t,这个质点的位移都由这个式子给出

Consequently, for this object the position y, at any time t is known to be 15+10t-5t^.

因此,对这个物体来说,在任意时刻的位移y,就应该为15+10t-5t^

I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.

你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2
