在轴向应变实验中研究了各种Nb/sub - 3/Sn导体。超导样品被焊接到被弯曲以产生压缩或拉伸轴向应变的衬底上。特别是在压缩应变范围内，临界电流减小比已知的标度定律预测的要小。通过改变带导体的热应变，研究了横向应变分量的影响。发现轴向应变实验可以用只依赖于应变张量的偏分量的上临界场来描述。最后比较了临界温度和临界电流随轴向应变的变化规律
Various Nb/sub 3/Sn conductors are investigated in an axial strain experiment. The superconducting samples are soldered to a substrate that is bent to generate a compressive or tensile axial strain. Especially in the compressive strain range the critical current reduction is smaller than predicted by the well-known scaling law. The influence of the transverse strain components is investigated in a tape conductor by changing the thermal strain. It is found that the axial strain experiments can be described by an upper-critical field that depends on the deviatoric component of the strain tensor only. Finally a comparison of the critical temperature and the critical current as a function of axial strain is made.>
