针对污水处理系统DO参数控制的复杂性和难以建立准确数学模型的特点，提出了一种用PLC对系统进行模糊控制的方法及实现。

For the complexity and difficulty of establishing an accurate mathematical model of DO parameter control in sewage treatment system, we propose a fuzzy control method with PLC to deal with it.

对AP238文件的译码处理不能像g代码那样逐行解释执行，而只能采取编译的方法，因此，STEP - NC数控系统的译码处理系统称之为编译器。

The decipher of AP238 file can't explain and execute line by line as G Code, and can only compile, thus the decipher process system of STEP-NC numerical control system was called as the compiler.
