本文指出线性化后的曲线拟合参数不是无偏估计量。

This paper points out that the linearized curve-fitting parameters are not unbiased estimations.

但这种方法进行的参数估计不是无偏估计量，因此其非线性拟合精度较低。

The parameter estimation achieved by this method is not unbiased. The precision of curve fitting is low.

利用参数的最佳线性无偏估计量及最佳线性不变估计量，估计出可靠度的近似置信下限。

The approximate lower confidence bound for the reliability of the component is obtained by using Best Linear Unbiased Estimate and Best Linear Invariant Estimate for parameters.
