核装置积分参数反应了其运行性能等种种指标,其不确定度分析显得尤为重要,是武器和工程上冗余设计的重要依据,有重要的国防和经济价值。随着计算技术的发展,算法本身带来的不确定度已经不是主要因素,而基础数据库引入的不确定度成为主导作用,如何确定和计算这部分不确定度也显得越来越关键。定义某积分量R对某参数q的灵敏度如下: The integral parameter of nuclear device reflects various indexes such as its operational performance, and its uncertainty analysis is very important. It is an important basis for redundant design of weapons and engineering, and has important national defense and economic value. With the development of computing technology, the uncertainty brought by the algorithm itself is not the main factor. However, the uncertainty introduced by the basic database becomes the dominant factor. How to determine and calculate this part of the uncertainty is also becoming more and more crucial. Define the integral of a certain amount of sensitivity of a parameter q as follows:
