曲线的形态和样品本身的结构、超导相构成通路的情况及引线接点质量等诸多因素有关。

It was found that the shape of a R-T curve depends on the construction of samples, communication of superconducting phases and the quality of the lead contacts, etc.

在使用较大的电流时，这一点特别重要。因为和接点两端的电压降相比，测试引线两端的电压降可能会比较大。

This is especially important when higher currents are used because the voltage drop across the test leads may be large compared to the voltage drop across the contact.

从阴极引脚接点互换和偏转线圈引线互换两个方面对“引脚线互换法”及其用法进行了阐述。

This article expatiates the lead-foot-line reciprocation method and its usages from the two sides of cathode lead-foot joint reciprocation and deflexion loop down-lead reciprocation.
