The matrix of the calibration coefficients

The matrix of the calibration coefficients related to "Improvement and feasibility validation of residual stress measurement in composite laminates using an incremental hole-drilling method". Here shows the matrice of the calibration coefficients on top and bottom surfaces, respectively.与《采用增量钻孔法（incremental hole-drilling method）测量复合材料层合板（composite laminates）残余应力的改进与可行性验证》相关的校准系数（calibration coefficients）矩阵。此处分别给出了上表面与下表面的校准系数矩阵。
