标度因数 meaning in Chinese
constant multiplier
scale factor
scalefactor
Examples
- For this quantity to be a meaningful measure of dispersion of the scale factors, the assumption of normality is again required .
该量是标度因数离散程度的一个有效的量度。就这个量来说，也要求正态性假定。 - 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
本文以光学陀螺为研究对象，开展了以下几方面的研究工作：本文对光学陀螺性能的两个重要指标?标度因数和零偏稳定性进行了较为详细的研究，其中包括陀螺的零偏b _ 0 、零偏重复性b _ r 、零偏温度灵敏度b _ t 、随机游走系数rwc和标度因数k 、标度因数的非线性k _ n 、标度因数不对称性k _ h 、标度因数重复性k _ r等等。 - 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
采用最小二乘极大似然估计和多项式拟合的方法,分析加速度计静态模型系数随加速度计壳体温度变化的规律,建立了- 20oc 50oc之间加速度计零偏和标度因数误差的温度模型,应用该模型对加速度计温度干扰进行补偿,补偿后,加速度计输出的拟合均方根误差一到二个数量级,并且基本上消除了加速度计输出随温度变化的趋势项,使得加速度计测量精度得到了明显提高。
