| 摘 要： | 一、引 言 在聚变研究中,环形等离子体的磁约束起着重要作用。目前托卡马克研究的进展令人鼓舞,其理论与实验比较符合,定标关系清楚。但是无论从聚变的最终目标来看,还是从实验的安排考虑,完全轴对称的几何形状给各方面部带来许多不便。人们希望知道如果把环形几何中加进直线段,或者把圆环改成不具有对称性的环形,会对等离子体约束产生何种影响?

| Abstract: | We have developed a computer code for solving the problems of three dimesional MHD equilibria and stabilities in a toroidal plasma. Making use of the code, we studied racetrack configurations as well as those of DRAKON(a Russiaa acronym for long equilibrium configuration) . It is found that as the ratio of length to width of the race-track increases the degree of distortion of magnetic surfaces increases until the nested system breaks down, and loses its equilibrium. With "DRAKON" the situation is the same |
