| 摘 要： | Discussed in this paper is finite amplitude ultralong wave under the influence of heat sources.The conditions arefirst investigated for the existence of periodic and solitary ultralong waves of finite amplitude in the Burger model withthe aid of Hamilton function and variation of total energy and then the wave analytical expression is formulated bymeans of the functional approximation and the Hamilton function as the motion invariant in nature.Results show thatthe finite amplitude ultralong wave influenced by heat sources is unlikely to generate a solitary wave solution and im-poses no constraints on horizontal divergence as opposed to the case with the effect of heat sources available.
