铁道部科学研究院于1992年2月20日在北京对“混凝土枕轨道电路参数与信号频率关系的研究”成果进行了鉴定。随着我国铁路大量采用混凝土枕,并且混凝土枕轨道电路已有多种主要制式设备,采用多种频率信息,使得混凝土枕轨道电路在设计、运用和维修等方面都需要相应的较系统的参数定量分析和理论解释。铁科院通号所在多年混凝土枕轨道电路参数研究的基础上,进一步进行了参数与信号频率关系的研究,获
Ministry of Railways Research Institute of Science and Technology in February 20, 1992 in Beijing, “concrete pillow track circuit parameters and the relationship between the signal frequency” results were identified. With the large amount of concrete sleepers used in China’s railways and a variety of major standard equipment for concrete sleepers or track circuits, a variety of frequency information are used to make the concrete sleepers track circuits require more systematic parameter quantification in terms of design, operation and maintenance Analysis and theoretical explanation. Based on the research on the circuit parameters of concrete sleepers for many years, the further research on the relationship between the parameters and the signal frequency was obtained.
