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.

Methods: Between April and November, 2004, we carried out a cross-sectional study that administerd a self-assessed health questionnaire survey to the parents of 1,117 children from 14 elementary and junior high schools with high tension power lines hovering over the campuses. The control group was consisted of 2,204 children from 18 control schools. Multivariate multinominal logistic regression model was used to calculate the age and socioeconomic indicators adjusted odds ratios and the corresponding confidence intervals of clinical visits and health conditions within a one- month period prior to questionnaire survey in relation to the putatively hazardous exposure to magnetic fields.
