The accuracy of Helmhotz matrix is raised 10 times than that of spectrum, and the calculation speed is faster than that of the direct solution. In this way, the method can reduce the time of matrix inversion in 3dimensional implicit difference migration and can be used to real data processing.

因此，该方法的提出，在计算精度许可的条件下，最大限度地减少三维隐式差分偏移中矩阵求逆占用的时间，从而使得该方法能真正用于实际地震资料的处理。
