然后利用估计准则方法及快速多步最小二乘法（FMLS）辨识换热器的动态模型。

Then, a criterion of estimate and FMLS (Fast Multi-Step Least Square) algorithm proposed by the authors are used to obtain the dynamic model of the heat exchanger.

在此基础上研究了模型中系统参数及运动参数的标定问题，设计了一种全新的标定块，并使用该标定块根据最小二乘法和迭代法快速地实现了参数标定。

Then the system parameters and kinematical parameters is estimated and a new calibration block is designed, After that the parameters are determined as a result by the least squares method.
