由于一些A_(-15)结构化合物具有突出的超导性能,人们正在努力将这类材料制成可以投产的线材。为了使超导输电稳定,就特别致力于象人所共知的NbTi多芯复合体那样的多芯复合体。与NbTi相比,A_(-15)材料,例如Nb_3Se或V_3Ge,显示出较高的转变温度,较大的运载电流密度和较高的临界磁场。因此,这类材料适于制作高磁场用的小体
Due to the outstanding superconducting properties of some A _ (- 15) structural compounds, efforts are being made to make such materials into wires that can be put into production. In order to stabilize the superconducting power transmission, it is especially dedicated to a multi-core composite such as the well-known NbTi multi-core composite. Compared with NbTi, A _ (- 15) materials, such as Nb_3Se or V_3Ge, show higher transition temperature, higher carrying current density and higher critical magnetic field. Therefore, such materials are suitable for making bodies for high magnetic fields
