摘　　要：初步研究了环径比接近2的托卡马克堆芯等离子体的基本特征。这类位形具有非常好的使磁流体稳定的特性,可以基本排除等离子体破裂不稳定性。从H模约束要求和氘氚燃烧实验出发,讨论了相关的基本问题:比压极限和密度极限、基本等离子体参数间的调整、氘氚自持燃烧条件等。参数选取的基本依据是ITER和ITER FEAT的设计经验。The core plasma characteristics of a tokamak reactor with aspect ratio near 2 are studied. An excellent feature of this kind of plasma configuration is the very good stability merit against the plasma disruptions. Starting from the Hmode confinement scaling and requirements of deuteriumtritium burning experiments, some basic issues are considered such as the density limit, the beta limit, the adjustments of basic parameters, the selfsustainable burning condition, etc. Experience of the ITER and ITERFEAT designs is the benchmark of our study.
