By using the methods of mathematics analysis,we investigate the travelling wave solution of the KdVB equation under the assumption v~2》4μ.We prove that the tr
In this paper, the change of the Rossby parameter β with latitude is considered and the parameter is introduced and the β-plane approximation is extended into
In this paper,two kinds of asymptotic analytic expression of the Brusselator limitcycle are given by means of two simple methods.To some extem,they are better t
The present paper analyzes the relationship between the body speed and thecavitation noise.The results indicate that there is the limiting value of cavitation n
