摘要
用磁重联模型与Ｊａｈｎｓ等人提出的锯齿触发条件模拟了托卡马克中的锯齿振荡现象。对Ｔ－１０托卡马克上的一特定放电，将数值结果与实验作了比较。结果发现，在反转半径外的振幅太大，并且在破裂之前温度剖面太平坦，而中心温度较低。
The magnetic reconnection model has been employed to simulate the sawtooth oscillation phenomena in tokamaks with the sawtooth trigger condition proposed by Jahns et al.Numerical results are compared with the experimental results on the T 10 tokamak.It shows that the amplitude is too large outside the reverse radius and the electric temperature profile is too broad before collapse and the central temperature is too low.This result is associated with the fact that in a reconnection model the center safety factor is required to be nearly 1.
