摘　　要：对声致发光这一尚不清楚的非平衡态复杂过程 ,以平衡态近似作为上限 ,通过对Taleyarkhan等人实验数据的分析和氘氘聚变反应的反应率的计算 ,指出Taleyarkhan等人实验中测得的中子不是热核中子 .今后实验中如能测到大于～ 10 8n s的有效中子产生率才能显示“气泡核聚变”的反应温度达到了 10 6 — 10 7K .Sonoluminescence is an unclear and very complicated nonequilibrium phenomenon. Using the assumption of thermodynamic equilibrium to analyse the experimental data and evaluate the neutron yield of a deuteron-deuteron reaction, this paper points out that the neutrons detected in Taleyarkhan's experiment are not thermonuclear neutrons. If a neutron production rate greater than ～10 8n/s is detected in future experiments, then that may imply that the hot(10 6—10 7K) bubble fusion condition has been reached.
