Introduction The scattering theory of the elastic wave are widely used in the seismic engineering, oceanic engineering, civil engineering, geologic prospection and lossless prospection.
The scattering phenomena of the elastic waves is a wave phenomena when the elastic waves transmit in the medium which have not continuous interfaces or heterogeneous bodies, their direct effects result in the magnification of the local displacements or local stress concentration or earthquake, they have various harms, one of these is the breakage and the rupture of the engineering materials.

Engineering estimation method.
In the actual engineering design, the harmonics caused by reactive power is hard to gauge, so the above algorithm is actually not feasible.
In engineering designing process, the following reasonable harmonic control measures can be adopted except through choosing equipments to control harmonic source.
