摘要
提出了用分层抽样－重要性抽样复合法计算接管的断裂失效概率，并与直接抽样的MonteCarlo法进行了比较，结果表明：用复合法计算接管断裂失效概率不但精度高，而且大幅度节省机时，提高效率。
The compound method of stratified sampling and important sampling is proposed to calculatethe fracture failure probabicity of the nozzle, and compared with the Monte carlo method of direet sam-pling, the result shows: the compound method is highly accurate and efficient.
