查询词典 polynomial coefficient

AVO analysis is suggested for solving to solve the difficulty in identification of thin alternating layers in exploration of oilfields. It can improve the current method that has no thickness variable in the formula of reflective and is limited by sampling rates in calculation of the coefficient in the time of domain. Using the relationship of stress and displacement on two interfaces, this paper derives the spectrum of reflective coefficient for any incidence angle and thiekness of thim layer based on the equation of seismic wave propagation in the frequency domain.
