摘　　要：本文基于超导体幂指数模型对低温超导体和高温超导体的分流温度分别作了数值计算,计算结果与现有的分流温度估算公式结果符合的很好.本文还讨论了幂指数模型中不同n值对低温/高温复合超导体分流温度的影响,并对复合超导体分流温度做了数值计算,结果显示在相同传输电流下,低温/高温复合超导体的分流温度比传统低温超导体的分流温度高3.2K以上,这表明这种复合超导体较传统低温超导体具有更好的稳定性.Based on the power-law model of superconductor, the current-sharing temperatures for LTS and HTS were calculated respectively, the calculated results have a good agreement with the existing equation results. Moreo- ver, in this paper, the effect of different n-values in power-law model on the current-sharing temperature was also discussed, and the current-sharing temperature of a LTS/HTS hybrid superconducting conductor was numerically calculated. The calculated result of hybrid conductor shows that its current-sharing temperature can increase at least 3.2 Kelvin degrees compared with typical LTS at the same transport current. It indicates that the stability of this hybrid conductor is better than typical LTS＇s.
