为合理选择堆振荡器法实验条件, 利用数值求解和公式推导, 对影响测量精度的几项主要因素进行了分析。研究表明, 通过选择合适的反应性振荡幅度及频率, 可以提高堆振荡器法测量反应性的精度。由分析结果可知, 对于中子代时间较短的反应堆, 要使用堆振荡器法测量小反应性, 在测量条件允许的情况下, 应尽可能选择高频率的反应性振荡。

The reactor oscillator method is a method for measuring small reactivity, its measurement precision is related to the selection of experimental conditions. In order to select the optimal conditions of experiment, several major factors which affect measurement accuracy are analyzed by numerical simulation and derivations of formulas. The research shows that the accuracy of reactivity measurement with reactor oscillator method can be improved by choosing suitable amplitude and frequency of reactivity oscillation. According to the analysis result, for the reactor which has short neutron generation time, we should choose high-frequency reactivity oscillation.
