摘　　要：针对燃气轮机标准数学模型建立过程中难以得到解析关系式的问题,提出了Matlab回归函数法的新型建模思路;并以某型三轴燃气轮机压气机部分为例,对此方法进行了验证与说明。此外,推导出的数学模型可用于燃气轮机的无故障状态参数的计算。A new method of establishing math model based on MATLAB regression function is presented. In order to get the analytic relationship during the course of establishing the gas turbine standards math model. Taking a certain type of gas turbine compressor parts for example, the method is verified and illuminated. In addition, the mathematical model is derived which can be used to calculate the no fault of the state gas turbine＇s parameters.
