The linear equation of temperature against stress relieving under constant temperature raising rate was derived from thermal stress relieving equation,thereforo the initial curve determined for upper and lower limit of glass annealing can be converted into straight line, So that drawing error oould be minimized and determining accuracy could also be improved. By using least square equation the upper and lower limit of annealing temperature can be obtained dy computer very reliably and quiokly.
