首次采用季节变动模型对天津市滦河水源10年的水质情况和黄河水源4年的水质情况进行了分析评价,得出各个水质指标的长期趋势项回归方程,根据趋势模型和各水质指标的历史数据求出季节比sc ,在各个指标的季节平均值和对应的季节比( sc )的基础上,得到了各个水质指标的季节变化趋势值。 | | 4. | 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。 | | 5. | As the time trend function represent the impact of economic development on consumption , in the paper the semi - parametric model with deterministic time trend function is firstly used to make empirical study for cointegration test between actual consume and income per capita of chinese urban residents from 1978 to 2005 , and the results show that there do exists cointegration between consume and income with income having important effects on consume , while the time trend form is not as what we usually suppose
摘要由于确定性时间趋势项代表了经济发展等的因素对消费的影响，故本文首次基于带有非参数时间趋势项的半参数模型对我国1978 ~ 2005年的消费收入进行了协整检验，实证结果表明：转轨时期我国城镇居民人均收入与消费之间存在着长期均衡关系，收入是消费的一个重要决定因素；同时趋势项的影响也并不是如很多文章描述的那样具有直线形式。 | | 6. | Chapter 5 introduces sampling - holding device principle , types and main performance parameters . we discussed the relationship between the sampling and the s - h device . chapter 6 discussed the pre - processing of sampling data including the scale transforming , digital filtering , reducing oddity and eliminating or pick - up tread item as well as smoothing process of the sampling data
