| 摘要 |
The present invention relates to a method for testing the internal structure of a refractory part, characterized in that it comprises the following steps: a) by means of a transmission antenna, sending at least one electromagnetic wave, termed a "pulse", into the refractory part to be tested; b) by means of a reception antenna, receiving said pulse after reflection thereof by a reflecting zone of the refractory part; c) analysing the time offset between the two preceding steps in order to deduce the position, in the refractory part, of the reflecting zone, said pulse having a duration less than or equal to 0.5 nanoseconds. |
