摘要
本文系统的分析了波的结构特征,它不仅包含有波元的升降等特性,而且还包含有波元的凹凸等形状特性以及波的分级结构,并给出了相应的句法描述。通过对ST—T波的分析识别,验证了其有效性。
We are interested in one kind of signals whose main band-width is
relative narrow and whose measured signal-noise is relatively high, they play a very important role in diagnosis, either engineering or medical wave is a important characteristics in recognition of this kind of signals. Statistical recognition is not satisfactory for automatic recognition of them. Syntactic method appears to the authors to be a good way of recognizing them .
Based on the coding method introduced in [1,2],which include the features such as concavity and convexity, we present a method expressing the hierarchical structure of the wave, and give its syntactic description.
