Abstract To resolve the confusion of the constant temperature bath stability probability distribution, tests have been carried out. The maximum entropy principle is used to determine the probability distribution of stability at 0℃, 40℃ and -40℃. Probability density functions at the three temprature points are derived by the modified damp least square method implemented in MATLAB. Results indicate that the distribution of stabality is symmetric single-peak type, values concentrating on the area of 0℃, which is consistent with the results of normal distribution fitting.
