本文首次把求解温度场的有限元法用于计算玻璃退火时的温度分布,提出了在微机上计算第一类光学不均匀性的方案,并解决了计算问题。

In order to predict many important physical phenomena in a large-size glass during annealing the application of the finite element solution of heat transfer problems to the determination of the tempe ature distibution within axisymmetric glass being annaeled (the temperature change is slow) has been suggested for the first time in this paper. According to above result, this paper also suggests the calculation method of the nonuniformity of refractive index due to the nonhomogeneous structure of annealed glass, thus overcoming previous difficulty in the oaloulation.
