  1. Ever since the set - up of " situation and policies " course in some colleges and universities, a certain achievements have been obtained, and a great deal of experience has been accumulated, however, some existing problems are still worrisome, including the relatively backward teaching materials, lack of united course book, random teaching, comparatively simple and backward teaching methods, irrational teaching set - up non - standard teaching process, instability of teaching faculty and the lack of learning enthusiasm

    高校「形勢與政策」課自開設以來，取得了一定成效，積累了不少的經驗。但當前該課的效果令人堪憂，具體表現為教學資料相對滯后、沒有一本統一的教材、教學隨意性大、教學方法較單一、教學手段落後、教學時數安排不合理、教學過程不規范，師資隊伍不穩定、學生的學習興趣不濃等問題。
  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. But the most common noise is angle random walk, bias instability, rate random walk, rate ramp and quantization noise. in this paper, the random error model including the most common five noise as above

    對常見的五種噪聲因素包括角度隨機遊走、零偏穩定性、速率隨機遊走、速率斜坡和量化噪聲建立了陀螺隨機誤差模型。
  4. Then the unified approach can be applied to it to acquire the ensemble random evolutionary response. since the normal probability density function ( pdf ) may lead to instability of some sample systems when the random parameters taking sufficiently small negative values, an arch - like pdf and a more adaptable - pdf, together with the matching chebyshev polynomial approximation and gegenbauer polynomial approximation, are suggested. numerical examples show that the suggested methods are effective

    相比較而言，隨機模擬法的結果無疑是最可靠的，但是它的計算量嫌大；隨機攝動法的計算量遠小於隨機模擬法，但是它要求隨機攝動量必須是一個小量；正交展開法的計算精度好於隨機攝動法，其得到結果與隨機模擬法得到的結果幾乎吻合，其計算量略多於隨機攝動法，但與隨機模擬法相比要少的多，不過計算前的準備工作較費時。
