To improve the surface quality of flexible formation using plasma arc, its heat-flowdensity on unit area is controlled by controlling the swinging of the plasma arc with the alternate magnetic field.
The supercritical fluid has the following unique characteristics: low viscosity, high density, better performance offlow, mass and heat transfer, dis solution and so on.
前言：超临界流体具有黏度低、密度大，有较好的流动、传质、传热和溶解性能等特性。

The effects of the heat flux, wall temperature and flow resistance on the nondimensional entropy generation density have been discussed.
