Based on the comparison of main methods of measuring thickness,it is considered that the resistance strain measurement technique to measure the thickness of thin-wall vessel is more reliable. By the stress-state theory and generalization Hooke law,the numerical relationship between the wall thickness and the longitudinal stress and hoop stress at a given point for thin-walled cylindrical container is reasoned,and then by means of resistance strain measurement technique,a method to measure the wall thickness of cylinder container by measuring given point normal strain is found,and is of important engineering significance.
