PCA又为主成分分析，是一种特征提取方法， 它通过线性变换寻找一组最优的单位正交向量基，用他们的线性组合来重构原样本(PCA and the main component analysis, a feature extraction method, which by finding a set of optimal linear transformation unit orthogonal base vectors, with their linear combination to reconstruct the original sample)

语音识别是近年来发展非常迅速的一项计算机智能技术，广泛应用在语音控制、身份识别等多个领域。本次项目主要研究语音识别的预处理过程和特征参数的提取环节。通过对原始语音信号进行预加重和分帧、加窗，滤除低频干扰，提升对语音识别有用的部分，消除了部分噪音和失真。预处理之后进行信号的特征提取，主要选取了短时平均过零率和MFCC两个特征参数，应用matlab软件绘制波形图并提取特征参数矩阵，为之后的语音信号的识别打下了基础。(Speech recognition is a computer intelligent technology which has developed rapidly in recent years. It is widely used in speech control, identity recognition and other fields. This project mainly studies the pretreatment of speech recognition and the extraction of feature parameters. Through pre-emphasis, framing and windowing of the original speech signal, the low frequency interference is filtered out, the useful part of speech recognition is enhanced, and some noise and distortion are eliminated. After pretreatment, feature extraction of signal is carried out. Two feature parameters, short-term average zero-crossing rate and MFCC, are selected. Waveform diagram is drawn by MATLAB software and feature parameter matrix is extracted, which lays a foundation for speech signal recognition.)

一个MATLAB/Simulink模型，关于电动汽车动力电池健康状态（State of Health； 建模基于SOC估计； 模型比较简单，原理清楚，适合对电动汽车动力电池SOH的估计有兴趣的初学者参考学习，学习前请阅读2到3篇动力电池SOH估计方面论文，这样对理解模型更有帮助。(A MATLAB/Simulink model, on the electric vehicle power battery health status (State of Health Modeling based on SOC estimation Model is relatively simple, the principle is clear, suitable for beginners interested in electric vehicle power battery SOH estimation, it will be better to read 2 to 3 SOC estimation papers about battery SOH estimates.)

matalab程序好用便捷，关于宏观经济，有增长，有波动研究。(matalab program easy to use and convenient, on the macro economy, there is growth, there are fluctuations in research.)
