| 英文摘要 | Based on the research of the propagation rules of one-way seismic wave using pseudo differential operator and the symbol theory, we analyze the existing problems in Lie algebra depth Integral of single square root operator in detail Making use of the improved algorithm to perform large-step extrapolation of single square root operator and calculating Lie algebra integral and exponential mapping, we can finally obtain the analytical expression of seismic travel time Besides, we compare the coefficient corrections in symbol of Lie algebra integral and calculation error in medium with laterally linear velocity variation before and after algorithm modification The numerical examples prove that the improved algorithm converges faster, reduces the computing time and improves the numerical precision |
