Modulated Phase Lag Relations to Determine the Scaling Law of the Electron Thermal Conductivity in Tokamak

We propose a method to determine the scaling law of the electron thermal conductivity χ^(0)_(e)T^(λ)_(e)with modulating heat pulses.Relation between tempera-ture phase lag and parameters(χ^(0)_(e)λ)is established,from which the electron thermal conductivity in center region of CT-6B tokamak is determined.
