【文章內(nèi)容簡介】 reases monotonically with T and vanishes at a certain temperature T = Tc. Find the value Tc.研究關(guān)于溫度的函數(shù)Δ。證明Δ隨著T單調(diào)減小同時(shí)在T = Tc時(shí)為零。找出Tc值3. Gap suppression in a superflow. Critical current. 在超流中的能隙壓縮。臨界流Superflow in a superconductor is described by the order parameter with spatially varying phase, Δ(r)= Δ e2iqr , which is related to the superflow velocity by vs = q/m.起導(dǎo)體中的超流是用隨相隨空間變化的序參數(shù)Δ(r)= Δ e2iqr來描述的，它與超流速通過vs = q/m 聯(lián)系起來BCS quasiparticles in the presence of superflow are described by the Hamiltonian存在超流的情況BCS 準(zhǔn)粒子由以下哈密頓量描述 which can be dioganalized by a Bogoliubov
