D-s mesons are investigated in a semiclassic flux tube model where the spin- orbit interaction is taken into account. Spectrum of D- wave D-s is predicted. The predicted spectrum is much lower than most previous predictions. Analysis of some D-s candidates is made. D-sJ(2632)(+) may be a 1(-)(j(P) =3-/2 or 1 D-3(1)) orbitally excited D-s meson if it really exists. D(s)1(2700)+/- is very possibly the first radially excited 1(-) ( j(P) = 1-/2 or 23S(1)) Ds meson [the first radial excitation of D-S*(2112)(0)]. D-sJ* d2112_ 0]. D*(SJ)(2860) should be a 3(-) ( j(P) 5-/2 or 1(3)D(3)) orbitally excited D-s meson, and DsJ(3040)(+) is the first radially excited 1(+) (j(P) = 1/2(+)) Ds meson. Our conclusions are consistent with the latest BABAR experiment.
