为了探求半参数模型能否处理多种多样的系统误差,设计四组模拟算例,应用半参数模型的补充最小二乘法,分别探讨半参数模型处理恒定系统误差、线性变化的系统误差及周期性变化的系统误差的可行性。结果表明:半参数模型能够很好地分离出恒定的系统误差;削弱线性变化的系统误差的影响,无法反映其线性变化的规律;对于周期性变化的系统误差,当系统误差数量级与偶然误差的数量级相差不大且其周期与观测值个数接近时,半参数模型才能有效地分离观测值中的系统误差。
為瞭探求半參數模型能否處理多種多樣的繫統誤差,設計四組模擬算例,應用半參數模型的補充最小二乘法,分彆探討半參數模型處理恆定繫統誤差、線性變化的繫統誤差及週期性變化的繫統誤差的可行性。結果錶明:半參數模型能夠很好地分離齣恆定的繫統誤差;削弱線性變化的繫統誤差的影響,無法反映其線性變化的規律;對于週期性變化的繫統誤差,噹繫統誤差數量級與偶然誤差的數量級相差不大且其週期與觀測值箇數接近時,半參數模型纔能有效地分離觀測值中的繫統誤差。

To explore the capability of the semi-parametric model dealing with the various systematic errors ,four sets of simulation examples are designed ,and the supplementary least squares method of the semi-parametrc model is adopted to explore the feasibility of the semi-parametric model dealing with the constant systematic error ,linear-changed systematic error and cyclical changed systemic error respectively .The results show that the semi-parametric model can separate the constant systematic error well ,weak the impact of the systematic error of linear change ,and can not reflect the regular pattern of linear change ;Regarding the systematic error with cyclical changes ,when there is little difference in the mag-nitude of the systematic error and accidental error and the cyclical systematic error has low frequency and less correlation with observed values ,the semi-parametric model can handle the systematic error of observed values effectively .
