摘要：

The NA49 collaboration has taken data of central Pb-Pb collisions at beam energies from 20 to 158 GeV per nucleon. The large acceptance of the detector allows to study particle yields in full phase space. In this paper we present recent results on strangeness production ( K, Lambda and phi) in this energy range and compare to measurements at lower and higher energies. The K+/pi(+) and Lambda/pi ratio shows a pronounced maximum around 30 A.GeV, whereas the K-/pi(-) and (Lambda) over bar/pi ratio exhibits a continuous rise. The phi/pi ratio also increases monotonically with beam energy. First results on multi-strange hyperon production at lower SPS energies are presented.
