摘　　要：The research of LTS/HTS hybrid conductor is a more recent topic in superconducting domain,and the current-sharing temperature is a key parameter to identify the characteristic of superconducting material.In this paper,based on the power-law model,the current-sharing temperatures for LTS and HTS were calculated respectively,and the calculated results have a good agreement with the existing equation results.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 0.2 K compared with typical LTS conductor with the same normalized transport current,so that the stability of this hybrid conductor is better than typical LTS supercondutor.It indicates that this LTS/HTS hybrid conductor as the substitutes of low-temperature superconductor,will have a wide application prospect and talent commercial value.The research of LTS/HTS hybrid conductor is a more recent topic in superconducting domain, and the current-sharing tempera- ture is a key parameter to identify the characteristic of superconducting material.
