Paper Abstract

The experimental researches on excitation in Plexiglas of slow components of a solitonic-type Wave of change of reflection and conductivity (WCRC) are continued. Such discrete velocity excitations by a pulse of the CO2 laser (as first for ceramic HT SC samples) were found out by us in 1992. The results of soliton study in experiments with the various real condensed materials represent fundamental interest. We undertook the experiments with the use of the thermocouple as the detector with the purpose of increase of reliability of results received earlier by other methods, especially in relation to the sign of parameter variation in WCRC. Thus the assumption proves to be true stated by us before, that the arrival of a studied in Plexiglas results in local decreasing of temperature. The records of thermal processes in a copper foil sample for times in hundreds seconds after a stimulating pulse have allowed to register repeated passage through the foil several WCRC components with velocity of the order of μ/s. It is 104 times slower speed than in the first experiments of 1992.
