| Abstract: | In order to study the accuracy for defectometer to locatc the defects, three kinds of methods of taeasuring front distance, that is b value, of angle sensor were discussed. It is believed that the accuracy obtained by multi - points measuring method is higher than that of two - points method, in addition, the accuracy of one - point method is the lowest. |
