06是次发放涉及特首、司长和局长的民望数字，由于调查周期不同，同步变化应以同步周期的数字比较。
Active underwater acoustic positioning / tracking systems locate target by measuring the range from object to receiving sensors . usually the target - receiver range can be got by the propagating time of a signal pulse . if this propagating time is larger than the pulse repetition period , it will mean that more than one signal pulse are on propagation
主动水声跟踪定位系统通过测量脉冲信号的传播时延可以测得目标相对接收机的距离，当此传播时延大于系统同步周期时，时延测量就会呈现不确定性，可能相差若干个重复周期，导致定位解多值，称之距离模糊现象。
