This thesis is organized in two parts : the first part of this thesis focuses on strangeness production at sps energies . the strange baryon and strange meson pro - duction at sps energies are modeled via luciae model which includes the reseat ter - ing 我们的工作目标主要集中在用建立在强子和弦机制上的高能核反应模型- luciae ,模拟wa97和na49实验中的奇异重子和奇异介子产生的数据。
