等离子体能量约束的标度律在任何使基本等离子体方程本身不变的变换下都必须是不变的。因此，即使能量损失的计算可能相当棘手，也可以对标度律施加约束。这些约束条件来自几个等离子体模型，并显示出该模型的特性。因此，除了减少必须凭经验获得的参数的数量之外，这些结果还可以描述哪些等离子体模型适合于计算损失。它们表明，目前提出的托卡马克的经验标度律与许多传统的等离子体模型是不相容的。
Scaling laws for plasma energy confinement must be invariant under any transformation which leaves the basic plasma equations themselves invariant. Hence, constraints can be placed on the scaling laws even though the calculation of energy loss may be quite intractable. These constraints are derived for several plasma models and shown to be characteristic of the model. Hence, in addition to reducing the number of parameters which have to be obtained empirically, these results could delineate which plasma models are appropriate for the calculation of losses. They show that the empirical scaling laws at present proposed for tokamaks are incompatible with many conventional plasma models.
