  Inclusive momentum spectra are measured for all charged particles and for
each of $\pi^{\pm}$, $K^{\pm}$, $K^0/\bar{K^0}$, and $p/\bar{p}$ in hadronic
events produced via $e^+e^-$ annihilation at $\sqrt{s}$=58GeV . The measured
spectra are compared with QCD predictions based on the modified leading log
approximation(MLLA). The MLLA model reproduces the measured spectra well. The
energy dependence of the peak positions of the spectra is studied by comparing
the measurements with those at other energies. The energy dependence is also
well described by the MLLA model.
