摘　　要：采用一级微扰理论研究了有效增殖因子Keff随截面变化的灵敏度 ,以GODIVA和ZPR 6/7两个快中子基准装置为例 ,计算了它们的Keff相对于 ν值、裂变截面和俘获截面的灵敏度函数 .经对计算结果分析和与FORSS计算结果的比较 ,表明计算正确反映了问题的物理意义 ,结果可靠 。The first order perturbation theory is used to calculate the sensitivity profile of K eff in fast facility. The calculated formulas are given in the sphere co ordinate. As an example, the sensitivity profiles of K eff to ,σ n,f and σ n,γ of GODIVA and ZPR 6/7 are all calculated. The results are also compared with those of FORSS. The calculation results have correct physical meaning and are reliable for application in the actual benchmark review.
