摘　　要：分析了某贮存地导弹产品温度、湿度载荷的统计规律、相关性和联合分布,研究了二维载荷谱的编制方法,获得贮存库的湿热载荷密度函数。考虑到产品贮存的多地性,采用权重系数法,计算获得产品多贮存条件下的联合概率密度函数。运用概率密度法,编制8×8二维环境载荷谱,给出了产品自然贮存环境载荷剖面,为导弹加速贮存试验和贮存期评估奠定基础。We have taken the statistical analysis for temperature and humidity load of the missile production in a storage test field, estimated their joint distribution, and put forward the two-dimensional spectrum-making method. Based on the pertinence analysis and weight coefficient method, we obtain the joint probability density function of environment load for missile productions under kinds of storage conditions. Using the probability density method, we design the 8×8 two-dimensional environment load spectrum, and have given normal storage environment load profile. It is a good base for the missile production to take accelerated storage testing and estimate storage lives in the future.
