此程序是应朋友的 老婆单位的要求写的，是用于本单位内工程资料的管理,关于数据操作是用的数据库控件，不过里面也有隐藏的非数据控件的操作方式-this procedure is a friend of a friend"s wife to write the requirements, the unit is used within the engineering data management, data on the operation of the database component, but there are also hidden-data control mode of operation

说明：  Matlab表情识别，特征脸[1 ]作为面部表情分类的方法。首先，利用训练图像创建低维人脸空间（pca）。这是通过训练图像集主成分分析（PCA）及图片主成分分析（即具有较大特征值的特征向量）获得的。 结果，所有的测试图像以所选择的主成分表示，计算投影图像与所有投影列车图像的欧几里得距离，选择最小值以找出与试验图像最相似的训练图像。(The feature face [1] is used as a facial expression classification method. Firstly, a low-dimensional face space (pca) is created using training images. This is obtained by training principal component analysis (PCA) of image set and principal component analysis of image (i.e. eigenvectors with larger eigenvalues). As a result, all the test images are represented by the selected principal components, the Euclidean distance between the projected image and all the projected train images is calculated, and the minimum value is selected to find the training image most similar to the test image.)

说明：  一个练习打字的游戏，字母下落，恩与字母相同的键就可以大落字母。(a practice typing games, in alphabetical whereabouts TU with the same letters on the keys can drop large letters.)
