摘要：

We present the numerical simulation of a single internal working surface which farms along the body of a supersonic jet with periodic variations in the magnitude of its velocity. The structure, the evolution and the observational properties of this flow are analysed. We make a qualitative comparison with previous analytic predictions, simulations of the complete jet and observations of Herbig-Haro jets. The apparent lag of the knots of emission with respect to the jet flow (which has been observed in some jets) can be explained by this model.
