Seismic body-wave tomography on the local scale is a technique of imaging 3-D velocity and/or attenuation structure of the Earth,according to minimum principle of difference between theory arrival time and observe arrival time.Hence,the accuracy of observe arrival time is very important to this technique.In practice,observe arrival time include more or less error,such as artificial error,instrumental error,among which some error is a value which increase with increasing of time.The paper propose a new technique,which can eliminate an effect of the value which increase with increasing of time on the inversion results,and validate the correctness and feasibility of this technique.
