摘　　要：由于磁带回放的不稳定性及磁带与处理机的不匹配 ,导致由磁带导入硬盘的数据误码率很高 ,影响了送入处理机的数据可用率。结果显示 。For the instability of tape palyback and the unmatching of tape and correlator, the error rate of data is too high to access data to correlator effectively. The effectiveness of the accessible data is improved by using checking software programming. The results show that it does work.
