| Abstract: | In this paper, problems commonly existing in the curved raypath tomography were examined and analysed before everything. Based on the 2-D model characterized by mesh node local linear function,an algorithm for seismic travel time tomography with high accuracy was given. Such an algorithm is characterized by; (1 )By rotating and translating the local coordinates,the extraction of the coordinates of ray-path and part of the procedure of inversion calculation could be simplified) (2)By means of the algorithm recommended, the analytical formula for calculating the Jacobin matrix was derived and it is simpler than that derived by N. D. Bregman,et al. |
