Abstract: We have investigated the yield and the spectrum of the K- mesons in the heavy-ion collisions with the relativistic RBUU approach. It's found that the ratio of the yield of K+ to K- depends on the size of the nuclear systems. One main reason is caused by the absorption effect of the K- mesons in the nuclear medium. We have found that the mean-absorption path of the K- mesons are different for light nuclear system and for the middle or heavy nuclear systems. The extent of the absorption of K- mesons is different for different elementary production channels. It's one important reason to make the channel Bπ→K-X play an important role in the K-production, especially for light and middle systems.
