摘要
堆振荡法是测量小反应性的方法之一。本工作以点堆动态方程为出发点,给出零功率反应堆传递函数的表达式。对三角波输入情况进行傅里叶分析后得到振荡反应性的表达式。在零功率反应堆上进行了振荡控制棒实验和振荡铀样品实验的反应性测量,本实验测量结果与周期法实验测量结果相符。
The oscillator method is one of the methods for measuring small reactivity.According to the point-reactor kinetics equation,the expression of zero power reactor（ZPR） transfer function was deduced.Based on the Fourier analysis of the triangular wave input,the expression of oscillation reactivity was gotten.Validating research was made on ZPR,including oscillation experiments of control rod and a sample.Comparing with the triangular wave technique research of the reactivity measurement and the period method,the result is agreement.
