We analysed d=10,0(32)superstring theory with a cosmological constant for possible Kaluza-Klein cosmologies.In the former case(scalar fieldФ=constant)we find an oscillating(2+l)-dimensional antide Sitter universe with a constant value for all fields on the internal dimensions,which are S^(1)×S^(3)×S(3).In the latter case,it is not possible to get.a power law form solutions.In the oscillating solutions the induced cosmological constant is less than 10^(-120)Mp^(-4) calculated according to supergravity theories.
