However, organism can react to the stress actively and the mutagenesis is not a passive event. sos response is employed in dna damaging agents challenged e. co / i, to cope with abnormal conditions
當受到外源dna損傷因子的攻擊時，大腸桿菌e . coil能啟動sos反應以應對不良環境，提高對致損傷刺激的耐受能力，減少損傷的發生。 -
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
工程實踐中常用於應力檢測的方法有電阻應變法、巴克豪森法、 x射線法和超聲波法等。同其它檢測方法相比，超聲波應力檢測法具有靈敏度高、準確性好及可操作性強等優點，從而成為一種公認為最有前途的無損檢測方法。
