摘要：

We use recently obtained two-loop string coupling constants to analyze a class of string models based on orbifold compactification. Assuming weak coupling at the string scale m(s) and single-scale unification leads to restrictions on the spectrum of massive (M(Z) much less than M less-than-or-equal-to m(s)) matter supermultiplets and/or on the Kac-Moody algebra level.
