级数型T_c公式的进一步研究

A FURTURE RECEARCH OF THE SERIES STYLE T_c FORMULA

本文利用λ（ｎ）的新的近似计算方法，求出了Ｅｌｉａｓｈｂｅｒｇ方程在Ｔ＝Ｔｃ时的解，得到了下面的强耦合超导临界温度Ｔｃ的级数表示式：其中α１（μ）仅是μＸ的函数．新的Ｔｃ公式表明，Ｔｃ只依赖于电声耦合参数、库仑赝势μ和对于有效声子谱α２（ω）Ｆ（ω）的二次矩＜ω２＞．

In this paper, We have used new approximate calculating method of the λ(m) and solved the Eliashberg eguation for T=T_c obtained a series exprasion for the strong coupling suDerconduCting critical temperature Where d_1(μ) depend upon μ only, this new T_c formula shows that To is determined only by elecrtico tron-phonon coupling constant λ=2 α2 (ω) F (ω), coulomb pseudopotential μ and by the sguare moment <ω￣2> of the endive phonon spectrum α￣2<ω>F(ω).
