摘要：
The surface resistance of Be of different purity and its alloy with Al .(50%Be-50%Al) is investigated in the temperature range 4.2-300 K in the frequency region 0-10(10) Hz. It is shown that in the temperature interval (in the vicinity of 77 K) where beryllium is a dc hyperconductor, the surface resistance of pure beryllium and the alloy has the lowest value as compared to other metals including aluminum. The temperature dependence of the surface resistance of Be and its alloy is successfully described by classical formulas of electrodynamics. (C) 1999 American Institute of Physics.
