在ASDEX的欧姆和束加热L模式放电中，通过选择安全系数q/sub a/，电子温度（T/sub e/）轮廓形状可以在很宽的范围内变化。相反，功率沉积分布对T/sub e/-分布形状没有影响。在无电流的WVII-A仿星器等离子体中，没有发现这种不变性，一个独立的约束似乎固定了托卡马克的电流分布j（r），它定义了电子热输运的条件。
Both in ohmically and beam-heated L-mode discharges of ASDEX, the electron-temperature (T/sub e/) profile shape can be varied over a wide range by the choice of the safety factor q/sub a/. The power-deposition profile, on the contrary, has no effect on the T/sub e/-profile shape. In current-free WVII-A stellarator plasmas, no such invariance property is found. An independent constraint seems to fix the current distribution j(r) of the tokamak, which defines the conditions of electron heat transport.
