The temperature dependence of the thermal conductivity к, the resistivity p, and the thermal emf a of the compound YBa2Cu30has been studied experimentally as χ was varied. The behavior of ρ and a at Τ = 300 К has also been studied as a function of the pressure up to 12 kbar. An estimate of the time scale of the relaxation of phonons with electrons rphe,, yields 10~12 s (Г = 100 K). This value would be typical of ordinary superconduct ors.
