摘　　要：对燃烧振荡一维数学模型进行了进一步推导,得出控制方程组耦合解,并利用简化后的方程解对燃烧振荡实例进行了计算.结果表明,数学计算值与实际测量值基本吻合,说明了本数学模型的正确性及其工程实用性.根据计算结果调节燃烧工况,可有效削弱燃烧振荡现象带来的不良影响或减少燃烧振荡现象的产生,保证燃烧装置稳定运行.Mathematical model of combustion oscillation was further deduced, coupled solutions of control-equation group were given out, and several theoretic - calculation examples were listed. The results show that the calculated values are close to the measured values, testifying the validity and practicability of the mathematical model. Ill influences which are brought in by combustion oscillation phenomena can be weakened effectively through adjusting combustion conditions according to the calculation results and the stable operation of combustion equipments can be ensured thereby.
