单泡声致发光中的感应辐射过程

Induced radiation processes in single-bubble sonoluminescence

Fedor V. Prigara

摘要:

根据最近对热辐射理论的修正,热黑体辐射有一个诱导源。我们表明,在单气泡声致发光热辐射是由一个球形谐振器,与声致发光气泡本身,而不是合奏的基本谐振器发射热黑体辐射的情况下,开放的气体介质。对于给定的波长,谐振器的直径是固定的,这解释了来自声致发光气泡的闪光的相位的非常高的恒定性,这比驱动声波的周期的恒定性更好。

英文摘要:

According to the recent revision of the theory of thermal radiation, thermal black-body radiation has an induced origin. We show that in single-bubble sonoluminescence thermal radiation is emitted by a spherical resonator, coincident with the sonoluminescing bubble itself, instead of the ensemble of elementary resonators emitting thermal black-body radiation in the case of open gaseous media. For a given wavelength, the diameter of the resonator is fixed, and this explains the very high constancy in phase of light flashes from the sonoluminesing bubble, which is better than the constancy of period of a driving acoustic wave.
