针对线性和准粒子欧姆耗散，构建了约瑟夫森结链与导电衬底电容性相互作用的零温相图。在这两种情况下，作为一个整体的链的相干（超导）和非相干状态之间的相边界被分裂成4段奇点。在有限的温度下，零温超导性被破坏，并且只有通过链R的电阻随温度T的代数下降才能表现出来：R <$Tλ。在相图的不同区域找到了指数λ的值，包括在相边界的不同段上它所接受的普适值。阐明了相图上出现的附加相变的物理意义。
Zero-temperature phase diagrams of a Josephson junction chain interacting capacitively with a conducting substrate are constructed both for a linear and quasi-particle Ohmic dissipation. In both cases the phase boundary between coherent (superconducting) and incoherent states of a chain as a whole is split into 4 segments by singular points. At finite temperature, zero-temperature superconductivity is destroyed and manifests itself only through algebraic decrease with temperature T of the resistance of the chain R: R ∝ Tλ. The values of the exponent λ are found for different regions of phase diagrams, including universal values accepted by it on different segments of the phase boundary. The physical meaning of additional phase transitions present on phase diagrams is clarified.
