摘要
将混沌理论与电路理论相结合，分析了一些能产生混沌的电路，对帐篷映射（ｔｅｎｔｍａｐ）迭代产生混沌的基本原理和性质进行了研究，并在仿真试验的基础上，设计出一种基于帐篷映射的差分混沌电路。根据混沌的初值敏感性以及输入值和混沌轨道的一一对应性，在理论上提出并论证了利用符号动力学的基本理论度量被测信号的可能性，将混沌电路应用于传感器设计，并成功地完成了基本模型试验，给出了基本的实验数据及其分析，开拓了混沌理论应用的新领域，同时也为探索新型传感器提供了一条可能的途径。
The chaos theory and the circuit theory are combined to analyze several circuits which can produce chaotic phenomena. The principal and characters of the tent are studied. A differential chaotic circuit based on the tent map is designed by simulating experiments. According to the character of chaos, the sensitivity to the initial conditions and the consistenlcy between the input value and the chaotic trajectory. The possibility of applying the basic theory of symbolic dynamics to measurment is presented and proved. Then, the basic model of the transducer is realized and the basic experimental results are given. The new area of the application of chaos is exploited. Meanwhile, it provides a new method of exploring the structure of new type of transducer.
