Taking Chen's rational mechanics as a theoretic basis, this paper studied wave phenomenon of transitional minimum plane wave in deformed media which have extremely long period and slow speed,expounded that the effective elastic parameters of seismic wave are determined together by intrinsic character and current deformation of formation and discussed the relative theoretic foundation of structure stress interpretation with seismic data. In the paper,wave equation of one dimensional limited deformation is derived in detail at first,then its specific solution and related computational formula are discussed.The results have some feasibility and practical value in using evolutionary information of seismic wavefield to carry out the structure stress inversion and interpretation in seismic prospecting.
