| 摘 要： | 分析了光纤传感器进行双参量测量时，系数矩阵的态性对待测量精度的影响，提出采用对系数矩阵进行预处理的方法，使得处理后的矩阵由病态变成良态。用方法对文献「４」和文献「５」给出的系数矩阵分别进行了处理。处理后，文献「４」系数矩阵的条件数从３４２降低到４，文献「５」系数矩阵的条件数从１６１降低到３，传感器输出不确定主降低了两个数量级。

| Abstract: | The effect of the condition of the coefficient matrix obtained from the simultaneous measurement of two parameters by fiber optic sensors on the error of the measurants is analyzed. A pre procession method to transform the matrix from the illconditioned to the well is proposed. The method is applied to the matrix in references and respectively, and the condition number in reference is reduced from 342 to 4, and in reference is reduced from 161 to 3. |
