• The liquid {,eunperature at bubble wall (I'?,.,.) is nurrnerically calcvtlated, including effect of thetlaerrnal conduction and that of the Jaterrt heat of non-equililoriunu evaporation and condensationat the bubble wall under a condition of the picosecorud soruoltrminescence and that of nonlight-emission. It is concluded that Tj,j is alnaost identical Go tire armbient liquid temperature dtrringbtrbble oscillations except at strong collapses. At strotag collapses, T?,j increases to the S2LlTl8order of magnitude with that of the maximurn teunperat,ure axtCained in the bubble. It is mainlydue to the thertnal conduction from the heated intericcr of the btubble. It is clari[iec1 that theenergy given to the surrounding liquid by the fat,ent treat ccf vapovx condensation from the time ofthe maxinaum bubble radius to that of the mininrtrtm raditzs is comparable to or naore tlaan thatby the tlaermal conduction, though the latent hea,t does rrot contribute rnuch to the increase ofT?,j at the final stage of the strong collapse.
