摘　　要：基于稳定性是衡量车辆检测器性能的关键指标之一,通过对稳定性影响因素的分析及相应实验,对微型感应线圈车辆检测器的稳定性进行了研究．结果表明：在一定时间内,在低频下频率稳定性更好；频率随时间的波动较大,随着观测时间长,频率总体表现出减小的趋势．文中在此基础上给出了提高检测器稳定性的处理方法．The stability is one of the key indexes to estimate detector＇s performance. The stability of mini inductive loop vehicle detection is researched by analysis of many factors and experiments. The experimental results show that the frequency stability is better when the frequency is lower in period of time, and it waves with time. With the in crease of observation time, the frequency shows a reduced trend on the whole. Based on it, the means of improving stability is provided.
