Meanwhile, it is been testified that the formula of staticfiltering and prediction is a special case of nonlinear filtering formulas.
因此，静态滤波和推估是非线性滤波公式的一种特殊情况。

The unit operation, a solid particles of dust and impurities by gravity, inertia diffusion, contact resistance leave, static comprehensive effect, dust settlement piling up in filtering elements.
Under static condition the acoustic wave detection is applied to study the filtering characteristics experimentally for two kinds of saturated rock specimens (sandstone and granite).
