说明：  三相DC-AC逆变器的谐波注入SPWM调制技术 性能指标：直流输入350~640V，三相交流输出线电压220V AC，输出功率5kVA，功率因数0.8，输出频率50Hz。(Harmonic Injection SPWM Modulation Technology for Three-phase DC-AC Inverter Performance indicators: DC input 350 ~ 640V, three-phase AC output line voltage 220V AC, output power 5KA, power factor 0.8, output frequency 50Hz.)

说明：  基于PCA的人脸表情识别，可以辨别高兴，愤怒和厌恶三种表情。 (In this project, Eigenfaces are used to classify facial expression. It has been assumed that, facial expression can be classified into some discreet classes (like anger, happiness, disgust or sadness) whereas: 1. Absence of any expression is the "Neutral" expression 2. Intensity of a particular expression can be identified by the level of its "dissimilarity" from the Neutral expression)
