Constringency analysis of the iteration method for continuation of potential fields in underwater geomagnetism navigation
水下地磁导航中位场积分迭代法收敛性分析

The iteration method for continuation of potential fields is the basic technique to gain underwater geomagnetism database. The astringency of integral-iteration method for continuation have not been testified,according to compression reflection theory can prove that the iteration method is constringency under some conditions,so it provides theoratical foundation for the basic technique of gaining underwater geomagnetism database.
