| dc.description.abstract | 以往方差估計理論建立於無系統誤差殘留的網形中，本文中提出在附有系統參數之平差模式下，如何以觀測量品質進行方差估計，並獲得網形最佳之權估計，同時求解未知參數與系統參數之估值與精度，並透過統計檢定檢驗系統參數之顯著性。實驗驗證台灣一等一級水準網(2001)中有三條測線殘留系統誤差，且估計水準點高程時受殘留之系統誤差影響產生偏差，故本文最後提出以附加三個系統參數重新進行平差，以獲得較接近真實狀況之水準網成果。 | zh_TW |
| dc.description.abstract | The techniques of the estimations of variance-covariance components used to be based on the assumption that there remained no systematic errors in the observations. This research brings forth the estimations of the variance-covariance components for the observation equations with systematic parameters. The proposed technique enables a more appropriate weight matrix to be formed for the network and hence more proper estimates for the unknown parameters, systematic and nonsystematic as well.
The experiments indicated that there were systematic errors remained in the three leveling lines of the First-Order class I leveling network of Taiwan (2001), and that the effects due to the systematic errors on the elevations and their precisions were eliminated by adding correspondingly three systematic parameters to the three lines of the Taiwan network. | en |
