基于第一性原理总能电子结构计算，我们发现在压力下测量的碱金属掺杂C_（60）富勒烯的超导转变温度T（c）在很宽的T（c）范围内与费米能级态密度有统一的线性关系。超导性的发现一致的可能机制进行了讨论。
On the basis of the first-principles total-energy electronic-structure calculations, we find that the superconducting transition temperature T(c) measured for alkali-atom doped C60 fullerites under pressure has an unified linear relation to the Fermi-level density of states in a wide range of T(c). Possible mechanisms for superconductivity consistent with the finding are discussed.
