摘　　要：采用磁重联模型与湍流模型 ,通过求解耦合了锯齿触发条件的一维输运方程 ,模拟了电子回旋共振加热(ECRH)情形下T 10托卡马克中锯齿振荡 .其中之一是近轴的ECRH ,另一个是远轴的ECRH ,数值结果与实验的比较表明用湍流模型得到了较好的预测结果 ,相反 ,由于重联模型的一些基本缺陷 ,不可能由重联模型得到满意的结果 .By employing two models, namely the reconnection model and the turbulence model, we present a transport code simulation of sawtooth discharges in T-10 Tokamak in the electron cyclotron heating phases, and the trigger conditions are also coupled into the transport code. In one discharge, ECRH was located nearly on-axis, and in another ECRH was located well off-axis. The comparison of numerical results and experiment data show that good prediction was obtained with the turbulence model. In contrast, due to some fundamental shortcoming of the reconnection model, no satisfactory fit could be obtained using the latter.
