Abstract：T-test uses t-distribution theory to infer the probability of difference occurrence, so as to compare whether the difference between the two averages is significant. The t-test method is used to carry out the period verification by calculating the synthetic standard deviation between the initial standard deviation and the verification standard deviation, and then calculating the t-value of the synthetic standard deviation. By comparing the calculated t-value with the corresponding t-value found in the corresponding t-distribution table, the sound nozzle type burner calibration device can be determined. Whether the state at the time of verification has been maintained.
