resistance variation method meaning in English

变阻法

There are several methods that are usually applied in engineering practice to examine structure stress : resistance variation method , barkhousen noise method , x radial method and ultrasonic method , etc . with comparasion to others , the ultrasonic method is acknowledged to be one of the most promising non - damaging inspection method in structural stress measurement filed for its fine sensitivity , veracity and good operation features
工程实践中常用于应力检测的方法有电阻应变法、巴克豪森法、 x射线法和超声波法等。同其它检测方法相比,超声波应力检测法具有灵敏度高、准确性好及可操作性强等优点,从而成为一种公认为最有前途的无损检测方法。
