摘　　要：某石油化工厂现有横河CS3000系统有4套,4套DCS系统平稳率计算程序完全相同。在维护过程中,发现每月都会产生相关平稳率的系统报警,经过分析,引发报警的原因是将0作为除数进行计算。在查找解决方法的过程中,如何将非0数作为除数,是消除报警的关键。Lanzhou Petrochemical Company’s petrochemical plant currently has 4 sets of Yokogawa CS3000 control systems, and the same as calculation procedures for the steady rate. During the routine maintenance, founding the system alarms related to the rate of stability are generated every month, and the cause of the alarm is due to the calculation of 0 as a divisor. In the process of finding a solution, how to use a non-zero number as a divisor is the key to eliminating the system alarm.
