| 英文摘要 | Based on the conventional rotation method, a classical optimal 17-point scheme has been proposed to improve the accuracy of wave equation modeling in the frequency domain. However, this scheme just can be applied to the square grid, which seriously limits its application. What's more, its accuracy is not the best. To extend this method to a rectangle grid and obtain the best accuracy, this paper proposes a new 17-point scheme based on the generalized rotation method, which can also be a called the double nine-point scheme, while the traditional 17-point scheme is just a special case of this new method. It has a higher accuracy than the average-derivative 17-point scheme. What is the most important is that the idea we construct the double nine-point scheme in this paper can help us extend the arbitrarily nine-point scheme to a double nine point scheme to solve all kinds of equations and then obtain higher accuracy in the frequency domain. |
