本文建立了一变参数自适应流量演算法以求非线性解或准线性解，提出了模型的参数识别法，并利用假设检验确定模型阶数ｎ．最后用实际算例进行了验证 In this paper, we establish a parameter-adaptive flow algorithm with variable parameters for nonlinear solution or quasi-linear solution. We propose a parameter identification method and use hypothesis testing to determine the model order n. Finally, the actual example is verified
