MG7 AT adopts small style equipped with traditional particular round, independent big racing car, overly aggressive in manner like a cheetah showing motive quality and character generated from a racing car. Reticulated grid is something of BMW as if telling us a historical relationship with BMW while the accessorial decorated bar on the periphery in strong and fashionable feature with the added cheomplate decorated bar both at front and back is the complementary to former metal wire, which proves more confident. Joining with cheomplate decorated bar on the high waistline, side window and afterbody enhances the modern feeling of the whole car as well as injects sumptuous feature. Wheel hub with individuality and motive feeling highly has won extensive praise from fans for cars.

MG7 AT采用了小脸造型，传统而独特的四圆、独立赛车大灯，个性张扬而激进，如同猎豹一般，显现出MG运动的气质和出身赛车世家的血统；双肾形网状格栅颇有些宝马的神韵，仿佛在向人们诉说着当年与宝马的历史姻缘，而外围增加的镀铬装饰条有力而时尚；前后保险杠上也增加了镀铬装饰条，与原有的金属腰线相得益彰，更显自信；车尾则在高腰线、侧窗和尾部加入了镀铬饰条，增强了整车的现代感，也增添了全车的华贵；轮毂造型更有个性，也更具运动感，在车迷中也是倍受好评。

Through the in-depth analysis of sentence and the sentence similarity computing method based on the keywords feature, the semantic feature and the syntactic feature, we propose a new method based on the multi-features fusion.

本文通过对句子的深入分析，在分别对基于词特征，词义特征以及句法特征的句子相似度计算的基础上，提出一种基于多特征融合的句子相似度的计算方法。

This method first maps training data into a high dimensional feature space through kernel function concept in Support Vector Machine and constructs orthogonal space in the feature space. Then it maps the data from feature space into the orthogonal space and computes Fisher criterion based global orthogonal discriminants.

首先应用支持向量机中核函数的概念，将样本隐式地映射到特征空间，然后构造特征空间的正交空间，再将特征空间样本映射到特征空间的正交空间，求解基于Fisher的全局正交鉴别矢量集。

Methods The QRS complex was firstly detected by using continouse wavelet transform, then the feature sets were detected by different feature extraction technique. Using linear discriminants, 4 types of FCC beats based on MIT/BIH arrhythmia database were classified and the classification performance of the feature sets was evaluated.
