本文将描述超导体各向异性的有效质量理论，即各向异性Ginzburg—Landau 理论（G—L理论），与临界态模型(CS模型)相结合，建立了高温超导带材的交流损耗与临界电流的各向异性理论模型; 利用不可逆应变的定义，给出了临界电流与应变的关系，并利用临界电流与应变的关系及Norris方程，导出了高温超导带材的交流损耗与应变的关系; 利用所建立的交流损耗与临界电流的各向异性理论公式，建立了依据超导短样带材的特性(临界电流，交流损耗），计算高温超导线圈交流损耗的数值计算模型.

Anisotropic theoretical models of critical current and AC loss of high temperature superconducting (HTS) tape in both DC and AC background fields were established based on the effective mass theory (the anisotropy Ginzburg—Landau theory) and the critical state model (CS model). A formula to describe the relationship between critical current and stress/strain was proposed by use of the definition of irreversible strain. The relation between AC loss and stress/strain was developed based on the critical current-strain relation and Norris’ formula. A numerical model to calculate AC loss of HTS coil was developed from the anisotropy theory of AC loss and critical current of short sample.
