The one order differential model and convolutional model of impedance formula of amplitude versus offset inversion were established. Impedance inversion formula from AVO was derived based on Bayesian framework. Methods of using Huber function as prior model parameter distribution and covariance matrix from well log as constrains were developed. The P-wave impedance, S-wave impedance and density were calculated by the conjugate gradient algorithm.

Methods Forty-four EBTB patients weredivided into an experiment group and a control group. All the patients of the two groups were treated with generalchemotherapy, the patients of experiment group accepted endobronehial decimeter wave therapy at the same time. Thepurulent secretion or caseous necrosis of the diseased region was drawn-off from the bronchi lumina by bronchoseope,then the antenna of the decimeter wave irradiator was inserted into the diseased region through the biopsy pore to per-form the radiation.
