1
Since there is no need to suppose the variance of error, the estimation method which we established is more efficient in application.
由于在估计方法中无需假定误差方差，因此，所构造的估计方法更符合实际应用情况。
2
The weight matrix is replaced by using weight coefficient, and avoids calculating inverse matrix of the error variance matrix.
用计算加权系数的方法代替了原来的计算加权矩阵，从而避免了求解滤波误差方差阵的逆矩阵。
3
If we heighten the precision of measuring equipment, the central difference's relative error of the estimation variance improved great, which is less than 10%.
若提高测量仪表精度，则中心差分法估计方差相对值明显改善，可提高到10%以内。
