  1. Since 1960 ", the methods for charactering time - frequency stability in time - domain have been in progress. the methods include allan variance, modified allan variance, time variance, hardamard variance, total variance, time interval error ( tie ) and maximum time interval error ( mtie ), of which tie and mt1e are usually used for telecommunication network

    自20世紀60年代以來，時間及頻率穩定度的表徵方法一直在不斷的發展，有阿侖方差、修正阿侖方差、時間方差、哈達瑪方差、總方差以及常用於電信網路的時間間隔誤差（ tie ）和最大時間間隔誤差（ mtie ） 。
  2. In this paper, optic gyro is viewed as the object of investigation and several aspects is investigated as follows. two important indexes - bias instability and scale factor were measured and investigated, including bias, its repetitiveness, temperature sensitivity, random walk coefficient and scale factor, its nonlinearity, asymmetry, repetitiveness. we make use of the allan variance method to separate the noise factors which affect the performance of the optic gyro, such as the angle random walk, bias instability, rate random walk, rate ramp, quantization noise, markov noise and sinusoidal noise

    本文以光學陀螺為研究對象，開展了以下幾方面的研究工作：本文對光學陀螺性能的兩個重要指標?標度因數和零偏穩定性進行了較為詳細的研究，其中包括陀螺的零偏b _ 0 、零偏重復性b _ r 、零偏溫度靈敏度b _ t 、隨機遊走系數rwc和標度因數k 、標度因數的非線性k _ n 、標度因數不對稱性k _ h 、標度因數重復性k _ r等等。
  3. The allan variance ( av ) analysis method is used to evaluate the hrg signal. the result indicates that the main random error of hrg is angle random walk ( arw )

    論文採用allan方差法對半球諧振陀螺的信號進行隨機誤差分析，分析結果表明，半球諧振陀螺的角度隨機遊走誤差是陀螺隨機誤差的主要部分。
