| Abstract: | The influence on the result of electrom etric, cased by the length of the conducting wire, the temperature as the variations of the pattern of the composed bridges is analysed. The method to reduce the error in the electrom ctric strain test is obtained through the theoretical analysis, calculations and the concrete structures. |
