Based on the principle of the cooperation, i. e, the correlative stochastic equations are located on the same probability level, the linear regression with fuzzy weight analysis is adopted to fit the test data, and the three - parameter stress - life curves of the mean and the mean square deviation are obtained
根據協同原理,即相關聯的隨機方程動態地處于同一概率水準,採用模糊隨機加權線性回歸方法對試驗數據進行擬合,得到了三參數的應力-壽命模型均值和均方差曲線,從而求得在給定應力下各可靠度的疲勞壽命。( 2 ). according to the system indices and requirements together with the technology characteristic, it researches the capture possibility of apt capturing system. then it introduces the common scan methods, such as raster, spiral, raster spiral, rose and lissajo. ( 3 ). it makes a detailed simulation analysis of the raster and spiral scan, analyze the connection between capture probability, capture time, system index at different capture resolution angle, capture range, vibration angle extent and terminal location distributing mean square deviation
其中對幾個關鍵部分進行了詳細分析:計算了目標角反射器的激光雷達散射截面( lrcs )值,研究了qd與ccd對目標位置角度的計算方法和空間解析度; ( 2 )根據系統指標和要求並結合現有國內技術特點研究了apt捕獲系統掃描的捕獲概率問題,然後分析了幾種常見的掃描方式:矩形( raster )掃描、螺旋( spiral )掃描,矩形螺旋( rasterspiral )掃描,玫瑰形( rose )掃描以及李薩如形( lissajo )掃描; ( 3 )對分行掃描和螺旋掃描進行了詳細的模擬分析,分析了它們在不同捕獲分辨角、捕獲范圍、振動角振幅和終端位置分佈均方差時的捕獲概率、捕獲時間與系統常數之間的關系。A batch least - squares maximum likelihood estimator is employed to calibrate the model coefficients of accelerometer and a polynomial post - fit method is used to establish temperature models of these coefficients. the temperature models of accelerometer bias and scale factor of accelerometer are established between - 20oc and 50 oc. after compensating the temperature error by using these models, the post - fit residuals of the accelerometer output have been improved to 10 ? 5 g, and the trend term of accelerometer changing with temperature basically vanished
採用最小二乘極大似然估計和多項式擬合的方法,分析加速度計靜態模型系數隨加速度計殼體溫度變化的規律,建立了- 20oc 50oc之間加速度計零偏和標度因數誤差的溫度模型,應用該模型對加速度計溫度干擾進行補償,補償后,加速度計輸出的擬合均方根誤差一到二個數量級,並且基本上消除了加速度計輸出隨溫度變化的趨勢項,使得加速度計測量精度得到了明顯提高。These rules consist of the total fit, the mathematics and fatigue physics, and the safety in tail predictions. an analysis of the test s - n data of 16mn steel weld joints reveals that the four models are reasonable if only considering the total fit as the conventional method did. but if by the present three rules, the appropriate models should be the normal or the extreme maximum value
根據先前提出的有限數據下良好假設分佈的確定方法,包括三個原則,即假設分佈形狀與誤差數據真實分佈形狀的一致性、預測的總體擬合效果、與疲勞失效機制的一致性和尾部預測的安全性,通過對線性均值s - n曲線擬合16mn鋼焊接頭s - n數據誤差的統計分析,說明應用一般推斷方法, 4種分佈都可合理地作為數據的統計模型,綜合考慮三原則后,極大值和正態分佈是可能的良好假設分佈。Taking two protein complexes, we performed md simulations on their candidate structures. according to the variations of the mean square deviation ( msd ) of the structures in md trajectories relative to the initial structures, the false structures can be excluded
以兩種蛋白質復合物為例,對其候選結構進行md模擬,根據md軌跡中構象相對于初始北京工業大學工學碩士學位論文摘要一構象的平方平均偏差( msd )隨時間的變化來輔助打分函數排除錯誤構象,得到了較好的結果。分享友人
