In the conventional 324 MHz DTL designed for China Spallation Neutron Source (CSNS) accelerating H^- ion from 3MeV to 132MeV, there are 7 tanks and currently the R&D of tank-1 is under proceeding, which has 29 cells and 29 quadrupoles. In design, the Tank-1 has a tilt field distributed partially in order to obtain most effective energy gain and low Kilpatric parameter. In order to decrease the difficulty of tuning the partial tilt field distribution, a new analysis named transfer matrix method is introduced. Verifying of the calculation and simulation of the transfer matrix has been finished with MDTFISH code, picking parameters from CSNS and SNS. Checking the method on the model tank in CSNS will be operated.
