drifting rate 中文意思是什麼
drifting rate
解釋
橫漂速率-
The results indicate that : with sa, the position precision of the integrated system, whose gyro drifting is 50 degree / hour and whose accelerator offset is 0. 001g, is 60 meters, its velocity precision is about 1. 75m / s out and its attitude angle precision is about 0. 25 degree. without sa, the position precision is about 20 meters, its velocity precision is about 0. 5m / s and its attitude angle precision is about 0. 1 degree. when the signal of gps is lost, the growing rate of the integrated system error is much lower than that of sins system
模擬結果表明：對于陀螺漂移為50度/小時、加速度計零偏為0 . 001g的組合系統，在有sa的情況下，位置精度大約為60米，速度精度大約為1 . 75米/秒，姿態角精度大約為0 . 25度；在無sa的情況下，位置精度大約為20米，速度精度大約為0 . 5米/秒，姿態角精度大約為0 . 1度；在gps信號丟失時，系統誤差的增長速度比純sins系統明顯減緩。 -
The optimizing methods of main etching parameters, such as etching rate, uniformity and selectivity, were investigated by the orthogonal experiment, and these results can be used for setting main process parameters, adjusting them with a drifting from desired conditions, and optimizing etching selectivity
應用正交實驗，進行了蝕刻速率、均勻性、選擇比等主要蝕刻參數的優化，得出主要工藝參數的設置方法和理想條件漂移時的調整方法以及優化選擇比的蝕刻方案。
