| 摘 要： | 研究了在先进实验超导托卡马克（EAST）上，由低杂波（LHW）和离子循环射频（ICRF）加热实现高约束模式（H模）放电的等离子体中的电子热输运情况。通过计算得出，H模相比于L模（低约束模式）电子热输运系数显著下降，特别是在等离子体边缘地区。在典型炮号（33068#、38300#、40823#）中，归一化温度梯度特征长度（R/LTe）的阈值应该是3~11。这三炮的约束时间与电子热输运系数相关，当电子热输运系数越大时，约束时间越小。

| Abstract: | Electron thermal transport in typical shots of high-confinement (H-mode) achieved with Lower Hybrid Wave (LHW),LHW and Ion Cycle Radio Frequency (ICRF) together is studied in EAST.The electron thermal conductivity during H-mode significantly decreases in comparison to L-mode,especially in the edge area.For these typical shots,the threshold value of R/LTe should be 3 to 11.The values of confinement time in three shots are related to the electron thermal conductivities.When the electron thermal conductivity is bigger,confinement time would be smaller. |
