Abstract :
In this paper, the KYZB paradox based on the nonlinear model of gas turbine is presented. The phenomenon is also illustrated by a periodic example. Because of this the solution drifts with the same phase velocity, and distorts gradually. Thus a method-overall shape rule as priority, piece selection as secondary, and drifting quantity as compensation-is introduced to rectify the drift by fitting the right hand functions. And the results of numerical examples are satisfied.
