小电容Josephson结的一维阵列呈现出电流-电压曲线，其特征是当偏置电压低于阈值电压{ital V}{sub {ital t}}时为零电流状态。阈值电压可以用外部磁场{ital B}来调制，该磁场可以调节阵列相邻电极之间的有效约瑟夫森耦合。{ital V}{下标{ital t}}对{ital B}的依赖性可以用一个模型很好地解释，其中{ital V}{下标{ital t}}是库珀对电荷孤子的注入电压。{版权所有}{ital 1996美国物理学会。}
One-dimensional arrays of small-capacitance Josephson junctions exhibit a current-voltage curve that is characterized by a zero-current state for bias voltage below a threshold voltage {ital V}{sub {ital t}}. The threshold voltages can be modulated with an external magnetic field {ital B}, which tunes effective Josephson coupling between adjacent electrodes of the array. The dependance of {ital V}{sub {ital t}} on {ital B} is well explained by a model where {ital V}{sub {ital t}} is the injection voltage for a Cooper-pair charge soliton. {copyright} {ital 1996 The American Physical Society.}
