In addition, Fourier finitedifferenceoperator is optimized desirably.
此外，本文对傅里叶有限差分算子作了必要的优化。

This method is based on the use of an "equivalent element medium" and the finitedifferenceoperator for an unsymmetrical star in anisotropic media.
在计算中引用了“等效单元介质”方法，采用各向异性介质中的不对称星形的差分算子计算程序。

Fourier finitedifferenceoperator can be adopted to ensure good fidelity of seismic wave field in wave field continuation of complicated geology structure, bringing high quality image.
