摘　　要：Energy confinement time taken from 135 discharges of the 2006 campaign in HL-2A is studied. The data obtained from the measurements are verified by comparing diamagnetic energy with the electronic kinetic energy calculated from both the electron temperature and density profiles. Two data sets for supporting the ITER L-Mode confinement database are generated from the 2006 campaign. The dependence of TE on the line-averaged electron density during ohmic phases is analysed. The comparison of TE in electron cyclotron resonance heating （ECRH） plasma as well as the existing ITER L-mode scalings is made. The results show that the energy confinement time is consistent with the ITER L-mode scalings.Energy confinement time taken from 135 discharges of the 2006 campaign in HL-2A is studied.
