由于未来的核聚变反应堆需要高性能的操作，期望利用内输运势垒（ITB）操作来改善反向磁剪切中的堆芯等离子体约束。在本研究中，首先将仿真结果与实验结果进行了对比，验证了模型的有效性。其次，利用环向输运分析链接程序TOTAL模拟了磁剪切和球团注入对托卡马克反应器中ITB形成的影响。在本次模拟中，确认了磁切变接近于零且存在密度梯度的条件下，采用反磁切变构型对含磁切变地层是有效的。c
Since a high performance operation is needed in the future fusion reactor, it is expected that the operation with Internal Transport Barrier (ITB) is utilized to improve core plasma confinement in the reversed magnetic shear. In this study, firstly, the simulation results are compared with the experimental result, and the validity of the model is checked. Secondly, the effects of the magnetic shear and the pellet injection on ITB formation are simulated in tokamak reactor using the Toroidal Transport Analysis Linkage code TOTAL. In this simulation, the ITB formation is confirmed in the condition that magnetic shear is nearly zero and the density gradient exists, and it found that the reversed magnetic shear configuration is effective in the operation with ITB. c
