摘　　要：pH影响着电化学腐蚀和金属溶解学的规律,所以研究pH如何影响压水堆核电厂的安全运行有重要意义。论文中将探讨:功率运行期间pH如何影响反应性的变化,建立数学模型并推导出反应性的pH系数,分析这种反应性效应的特点,结合核物理中核素共振现象,利用有效共振积分半经验公式,证明由理论分析得出的拟合曲线与实验结果一致。As the pH value affects the law of electrochemical corrosion and metal dissolution,it is very important to explore the effect of the pH value on the safe operation of nuclear power plant.The contents of this study includes：How the pH value effects on reactivity variations is firstly given during the period of power operation.Meanwhile,the pH coefficient of reactivity is derived and its characteristics are represented by mathematical modeling.Moreover,the semi-empirical formula with the effective resonance integral is used to verify the experimental result by combining the nuclide resonance phenomena in nuclear physics.As a result,the experimental results are well agreed with those provided by the theoretical analysis.
