摘　　要：介绍了高压釜水晶生长的两级计算机测、控系统的构成，着重讨论了下位机在实时多任务操作系统ｉＤＣＸ５１的运行环境下，任务的设置方法及应考虑的因素，给出了所使用的控制策略。系统的控制精度在＋１℃以内，很好地满足了现场工艺要求。This paper introduces the construction of two-level computer measurement and control system of rock crystal growing in the high pressure reactor. It focuses on the method of task imstallation and the factor which should be considered about the lower-computer in the running environment of Real Time Multi Task OS-iDCX51. The paper also offers the control tactics used. The system's control precision is about one centigrade,and it meets well the technological inquirements on the spot.
