| Abstract: | Based on the characteristic parameters of the background plasma and the experimental data of the spatial distribution for oxygen and carbon impurities in HT- 6M tokamak under ohmic heating,a program for computing the impurity tramsport is established. The behaviour of impurity transport is analyzed. The results show that the density of oxygen and carbon is 5% n. and 3% n.separately, the behaviour of impurity transport is anomalous, the diffusivity is 2. 0 m2 s-1, andeffective charge number is near 4. |
