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.
