The experimental data of the pull-off method to measure the surface tension coefficient is calculated in detail,and the accuracy of the measurement results is better at room temperature.A single measurement was performed under variable temperature. Due to the low accuracy of the temperature control device of the instrument and the small change of the surface tension coefficient with temperature,the measured value of each temperature point has a certain deviation,but the change trend of the experimental results is basically the same.
