| Abstract: | In this paper, a new approximate procedure is presented to simplify the potential equation of large-disturbing transonic flow in 2-dimensions. And an integral equation corresponding the potential equa-tion has been mathematically derived, in which the conditions of bond-aries and shock waves are treated in small-disturbing theorem. |
