The nonlinear parameter identification of fuel cell polarization curve was converted into two sub-problems of linear least square identification based on interval segmentation technique.
基于区间分段思想，将极化曲线非线性参数辨识转化为两个线性最小二乘辨识子问题。
Different from English, there are no interval marks between words in Chinese, so it is difficult for word segmentation to identify ambiguous words.
汉语不同于英语，词之间没有间隔标记。而汉语分词是文本分析的第一步，且存在歧义切分，因此分词问题成为汉语分析的首要难题。
