The aim of this research is to study the critical temperature depending on the pressure of one-band superconductor. We derive the exact equation of the critical temperature [Formula: see text] by using the BCS-like model. The effect of pressure and pseudogap on critical temperature has been investigated. The analytic form and the approximation of the critical temperature are shown. First, we consider the effect of pressure on the critical temperature and find that the critical temperature increased as pressure is increased which fits well with the experimental data of Tl-based and Bi-based superconductors. Second, the effect of the pseudogap on the critical temperature is considered. We found that the critical temperature is decreased as pressure increased which agrees to the data of [Formula: see text], the iron chalcogenides [Formula: see text], intermetallic compounds [Formula: see text] and [Formula: see text] superconductors.

临界温度对压力的依赖性

本研究的目的是研究取决于单波段超导体压力的临界温度。我们使用 BCS-like 模型推导出临界温度的精确方程[公式：见正文]。研究了压力和赝隙对临界温度的影响。显示了临界温度的解析形式和近似值。首先，我们考虑压力对临界温度的影响，发现临界温度随着压力的增加而增加，这与 Tl 基和 Bi 基超导体的实验数据非常吻合。其次，考虑赝能隙对临界温度的影响。我们发现临界温度随着压力的增加而降低，这与[公式：见正文]、铁硫属化物[公式：见正文]的数据一致，
