Abstract：
A simple method is introduced here to correct the bends of the charged tracks,due to the fring effect of the magnet in a forward spectrometer.
Because of the irregular magnetic fields caused by the fringe effect,the track of a charged particle will be twisted when it passes the magnet.By numerical integration,the slope corrections of the track both before and after the momentum analysis magnet have been made.With this method the before and after magnet track matching has been greatly improved and the background,due to the wrong matching,has been reduced.
