本文总结了托卡马克运行的约束条件。操作空间受到若干限制的限制，其中等离子体性能以及由此产生的聚变功率必须被优化。描述了最终导致放电终止并可能损坏第一壁的硬限制以及导致等离子体的能量含量（和产生的聚变功率）降低的软限制。操作限制可以概括为两大类：来自等离子体的过量辐射，以及违反全局或局部MHD稳定性边界。
This article summarises the constraints for tokamak operation. The operating space is restricted by several limitations among which the plasma performance and hence the resulting fusion power has to be optimized. Hard limits which lead ultimately to a termination of the discharge and may damage the first wall as well as soft limits resulting in a reduction of the energy content (and the generated fusion power) of the plasma are described. The operational limits can be summarized in two general groups: excessive radiation from the plasma, and violation of global or local MHD stability boundaries.
