Abstract
In induced-matter theory, a 4D non-empty physical space–time is obtained from the 5D Ricci-flat one by setting the extra dimension coordinate equal to a constant. On the basis of this theory, we construct a 4D physical space–time by choosing a certain supersurface equation F(xA) = 0 (A runs over 0 ~ 4). It is shown that, the 4D two-fluid FRW cosmological model can be obtained from 5D flat space–time by specifying F(xA) = 0 as x4-x0 = 0.
