在Wu等人的论文中，提出了一种基于约束总体最小二乘法计算三轴磁力计标定参数的有趣方法。该评论声称，为了构造该论文中公式（13）中的设计矩阵A的误差，应该使用未知的磁场强度，而不是该论文附录A中所示的测量磁场强度。这导致损失函数与原始论文中的方程（16）不同，因此应对主要算法进行相应修改。
In the paper by Wu et al, an interesting method was proposed to calculate the calibration parameters of a three-axis magnetometer based on the constrained total least-squares method. It is claimed in this comment that in order to construct the error of the design matrix A in equation (13) in that paper, it is the unknown magnetic field strength rather than the measured one shown in Appendix A of that paper that should be used. This results in a different loss function from that in the original paper, i.e. equation (16) therein, and hence the main algorithm should be modified accordingly.
