Resistance appears when quasiparticle injection current reaches some threshold value.

当准粒子注入电流超过阈值耐出现电阻。

Find out how many particles are contained in one quasiparticle. For that, consider a state with one quasiparticle added to the BCS ground state.

找出一个准粒子中包含的粒子数。为此，考虑将一个准粒子加到BCS基态时的态。

Double tunnel junctions have been used to investigate the properties of superconducting Pb films under quasiparticle injection. At high injection level an inhomogeneous gap state was observed.

用两个重叠的铅隧道结进行实验，当注入电流很大时在铅膜中观察到了非均匀能隙态，铅膜中出现非均匀态的功率阈值比铝膜大得多。
