Abstract：
A new three dimensional constrained method to reconstruct the charged particle tracks for the forward spectrometers is introduced.Using the method of least squares to solve the eqution,the parameters of the tracks can be obtained.In order to reduce the computing time,the two-dimensional x-line is used as the starting points.We generated some Monte-Carlo data and compare the results with the data by different methods.It is shown that this method has good resolution and accuracy.
