摘　　要：为克服导弹发射噪声场试验测量方法的局限性,基于间接边界元法,提出研究导弹发射喷气噪声分布规律的声学数值仿真算法.结合实际的工程项目,对这一算法进行了验证.结果表明,该声学数值仿真算法是可行和有效的,具有广阔的工程实用价值和应用前景.In order to get over the measurability limitations of the jet noise field when rockets are launched, an arithmetic based on indirect boundary element method （IBEM） and its numerical simulation research are presented in detail. As an example, the arithmetic was applied to an real launching experiment. The simulation result shows that the arithmetic is feasible, valid, and has good application perspective.
