We have studied on the effect of temperature especially on the fluctuation of the strength of glass under uniformly increasing load with time on the center of glass plate suspended freely at the two ends. The region of temperature was between the room temperature and 300℃. μ(t), the probability of breakdown at the time Ms described as follows, [numerical formula] Here, E_n(T) is the activation energy for breakdown when there is no applied load, f the load,β f the energy applied by external load, T the absolute temperatnre and k is the Boltzmann's constant. According to the result of experiment, β is not constant but depends on the temperature, having a minimum at about 150℃. The magnitude of E_n is some kcals/mol and increases with the temperature.
