| Abstract: | The mesures are studied to improve precision of detection curve fitting in concrete nondestructive testing. A calculational example indicates that it can gain higher precision to chose suitable form of function, to fit with piecewise-function, to aim least sum of relative error, to eliminate influence of outliers, or to apply artificial neural networks. And all above measures are based on least square method. |
