• The characteristics of double probes immersed in plasmas in which electrons and ions have drifted Maxwellian distributions are theoretically investigated by using an electronic computer. The results about a double probe which has "two frontal electrodes" show that the electron drift changes the inclination of the characteristic curve; therefore, the electron temperature estimated from the curve contains an appreciable error. On the contrary, the results about a probe which has "back-to-back electrodes" show that the electron drift shifts the idealized characteristic curve parallel to the potential axis of the figure and the ion drift parallel to the current axis, but the original pattern is still conserved; therefore, the estimated temperature is valid in this case as far as the drift velocity of electrons or ions is far lower than their thermal velocity.
