In this research, we investigated the critical temperature $\left(T_C\right)$, gap-to-$T_C$ ratio $\left(\frac{2\Delta }{T_C}\right)$ and isotope effect exponent $\left(\alpha \right)$ of s-wave superconductors under high-pressure envelopments, including the electron-phonon interaction and electron-Plasmon attractive interaction in the weak-coupling limit. The analytic formula of $T_C$, $\frac{2\Delta }{T_C}$ and $\alpha$ with non-pressure and under pressure cases were used. The numerical calculations showed that the under-pressure case had a greater critical temperature than the non-pressure case. The effect of pressure had a significant impact on the gap-to-$T_C$ ratio, and the isotope effect exponent exhibited a range between 0.30 and 0.75.

在这项研究中，我们研究了临界温度$\left({吨}_C\right)$, 差距到-${吨}_C$比率$\left(\frac{2\Delta }{{吨}_C}\right)$和同位素效应指数$\left(\alpha \right)$高压包络下的 s 波超导体，包括弱耦合极限下的电子 - 声子相互作用和电子 - 等离子体吸引相互作用。的解析公式${吨}_C$,$\frac{2\Delta }{{吨}_C}$和$\alpha$使用了无压力和有压力的情况。数值计算表明，负压情况下的临界温度高于非压力情况下的临界温度。压力的影响对间隙到-${吨}_C$比，同位素效应指数在 0.30 和 0.75 之间。
