To study a nonlocal electron transport in an aluminum superconducting quasi-one-dimensional structure, we measured negative nonlocal (local) direct current voltages in the structure in a magnetic field near the critical temperature. The structure is a normal-superconducting at $T_{cn}<T<T_{cw}$ ($T_{cn}$ and $T_{cw}$ are the critical temperatures for narrow and wide wires, respectively, making up this structure). Negative voltage arises due to a quasiparticle current flowing through the N-S interface. We plotted the experimental and theoretical temperature and magnetic-field dependences of current, resistance and voltage corresponding to the peak of negative voltage, taking into account either equilibrium or nonequilibrium superconducting fluctuations.

为了研究铝超导准一维结构中的非局部电子传输，我们在临界温度附近的磁场中测量了该结构中的负非局部（局部）直流电压。该结构是常态超导${Ť}_{Cñ}<Ť<{Ť}_{Cw}$ （${Ť}_{Cñ}$ 和 ${Ť}_{Cw}$分别是构成此结构的窄导线和宽导线的临界温度。由于准粒子电流流经NS界面而产生负电压。考虑到平衡或非平衡超导波动，我们绘制了实验和理论上温度，磁场对电流，电阻和电压的依赖性，这些电流，电阻和电压与负电压的峰值相对应。
