The resolution radio of tomographic imaging depends on the acquisition precision of seismic (acoustic) full wave form information.The present paper deals with the collection of characteristic information from seismic (acoustic) full wave form records,the establishment of three wave form records,the establishment of three layer neuron network model,the application of neuron network to the information collection of seismic (acoustic) full wave form records,such as the traveltime acquisition of initial wave.The paper also discusses the establishment of neuron network model and the study of neuron network model,with an emphasis on the characteristics of the initial wave when it appears.Aquantitative description is given,and its application to the information collection of seismic (acoustic) full wave form records has exhibited very high precision.
