    "abstract": "Phase drift and random fluctuation of interference visibility in double\nunbalanced M-Z QKD system are observed and distinguished. It has been found\nthat the interference visibilities are influenced deeply by the disturbance of\ntransmission fiber. Theory analysis shows that the fluctuation is derived from\nthe envioronmental disturbance on polarization characteristic of fiber,\nespecially including transmission fiber. Finally, stability conditions of\none-way anti-disturbed M-Z QKD system are given out, which provides a\ntheoretical guide in pragmatic anti-disturbed QKD.",
