提出了Ｌａｔｉｎ抽样与分层抽样相结合的复合抽样方法，对于提高抽样精度和效率都有较为明显的作用，特别适用于结构裂纹概率的仿真和其它应用工程仿真计算。在复合抽样仿真计算示例中，对某型导弹的燃汽发生器进行了抽样仿真计算，所得的抽样结果的精度和相关差都达到了令人满意的预期效果，与实验结果吻合。 The composite sampling method based on Latin sampling and stratified sampling is proposed, which has obvious effect on improving sampling precision and efficiency. It is especially suitable for the simulation of structural crack probability and other applied engineering simulation. In the example of compound sampling simulation, the gas generator of a missile is simulated by sampling. The accuracy and relative difference of the sampling results obtained are all satisfied with the expected results, which are in good agreement with the experimental results.
