摘　　要：本文采用线性扰动分析方法，获得了工程上常用的Ｍａｎｎｉｎｇ摩阻律所相应的各种河波波型的动力特征．在此基础上，得出了运动波、扩散波和惯性波模型的识别准则．本文的结果，对实际水流采用较好的数学描述或物理模拟，可提供一个粗略而快速的决策依据．The dynamic characteristics of various types of river wave corresponding to the Manning friction law, commonly used in engineering, are derived by using the linear perturbation method. On the basis of these characteristics, the identification criteria for the kinematic wave, diffusion wave as well as inertia wave are investigated. These criteria can be used as a basis to make a rough and quick determination for adopting a better mathematical discription or physical simulation for a real flow.
