摘要：

In a Monte Carlo code based on the Quark Gluon String Model it is shown that the fusion of strings produces an enhancement of Lambda, ($) over bar Lambda and phi production, and a reduction of K- production and total multiplicities. The results are in reasonable agreement with most of the experimental data for hadron-hadron, hadron-nucleus and nucleus-nucleus collisions, especially with the large ($) over bar Lambda enhancement, which is well reproduced. Predictions for Ph-Ph collisions at p(lab) = 200 GeV per nucleon are also presented.
