摘要
液体中的含气量是单泡声致发光相空间的重要参数,对声致发光气泡的运动及发光有重要影响。本文给出 了一种使用插入式荧光光谱含氧量计测量稳态单泡声致发光的液体中气体含量参数的方法,并对这一关键性参数 与气泡平衡半径R0和声压Pa的关系进行了具体的研究,再次验证了扩散平衡、化学分解假设理论。
Gas concentration in liquid is an important parameter in single bubble sonoluminescence (SBSL), which significantly affects the movement and light emission of the SBSL bubble. Gas concentration in a liquid is measured with an inserted fluorescence spectral oxygen sensor in the present research. Relations between the gas concentration and the others factors such as equilibrium radius and driving acoustical pressure are then studied experimentally. The dissociation hypothesis is again proved.
