摘　　要：文章提出变型文氏电桥电路仅需调节一个电阻器即可改变中心频率，使频率自动跟踪易于实现。在详尽分析电桥电路的基础上，阐明了指标要求与参数间的关系。The variant Wien bridge circuit presented in this paper makes the manufacture of auto tracking instruments easy because the variance of center frequency of circuit depends on the resistance of only one resistor in the circuit. Based on the detailed analysis of variant Wien bridge circuit, the relationship between indices and parameters and method for design of the circuit are described in this paper.
