摘　　要：我国VLBI网包括上海佘山、乌鲁木齐和昆明 3个观测站 ,以及上海天文台研制的两台站相关处理机。上海佘山和乌鲁木齐站已升级成MK4制式和只使用薄磁带 ,而昆明站只能使用S2制式。因此 ,实现相关处理机对不同制式数据和薄磁带的兼容 ,是我国VLBI网顺利运行的关键。给出了多制式VLBI观测实验和相关处理的初步结果 ,总结了相关处理机升级后的处理能力 。Chinese VLBI network (CVN) consists of one correlator and 3 stations located at Shanghai, Urumqi and Kunmin respectively. Shanghai and Urumqi stations have been upgraded to use thin tape only and MK4 tape format, but Kunmin station has only a S2 terminal. In order to make CVN operational, the correlator was modified to compatible with MK3A, VLBA, and part of MK4 and S2 tape format. A series of experiments for testing the correlator were conducted, and the preliminary results of those experiments were presented and analyzed. Capability of the correlator after upgrade was summarized, and the future work of the correlator were discussed.
