| Abstract: | :
Stokes' problem in physical geodesy needs some practical formulas to compute gra vity on geoid by measured values on the surface of the earth which affects accuracy of Stoke' problem In Molodensky' s problem because tellurold is irregular and

boundary condition is slope-differential, solving is inconvenient This paper sufficiently makes use of advantages of Stokes' problem and Molodensky' s problem, and proposes a new method determining shape of the earth and outer gravity field which is based on computing terms of high order in Taylor' s expansion This method not only has theoretical precision but also has property to compute conveniently in actual application |
