摘　　要：利用唯象损耗等效法和宏观唯象模型来分析高温超导微带传输线的传输特性。宏观唯象模型克服了传统二流体模型不适用于高温超导体的缺点,使计算结果符合测量值。本文给出了高温超导体YBCO微带传输线的传输特性计算结果,可见其衰减及色散都很小。因此结合唯像损耗等效法和宏观唯象模型可以使高温超导微带线的设计精度有很大提高。We use Phenomenological Loss Equivalence Method (PEM) and Macroscopic Phenomenological Model (MPM) to analyze the propagation characteristics of the high temperature superconducting (HTS) microstrip lines. MPM overcomes the shortcomings of conventional Two Fluid Model, which does not suit for HTS, and makes the calculating values conform to the measuring results. The calculation values of YBCO HTS microstrip line are given. From these results, the attenuation and dispersion are very small. The better design results using PEM and MPM can be obtained.
