摘要
论述了外热式真空炉温度控制模型，阐明了采用动态控制方法，可严格保证零件的工艺要求，尤其是升、降温段的速率要求，还详细讨论了其微机控制软件的设计，该控温软件主要由管理模块、２ｓ中断服务程序和１０ｍｓ中断服务程序３部分组成。
Describes the dynamic control methods used to meet the technological requirements during the heating and cooling stages of furnaces of the muffle type, e. g. externally heated vacuum furnaces. Also describes in detail the furnace temperature control software, with its three parts: management program, 2 s interrupted handling routine and 10 ms interrupted handling routine.
