利用kinect获取原始的音频波形，得到四声道的pcm波形。(Use kinect to get the original audio waveform, get pcm waveform four channels.)

模仿Oracle exp/imp的数据导出导入工具(Oracle exp/imp abcdefg)

主要实现如下功能： 1.快速查询某件产品的进价、售价和供货单位。 2.快速查询供货商的的电话，以便打电话询问商品是否有货。 3.可以按照数据库各字段进行排序显示 DB下为Sql2005数据库，附加即可 注意：该系统需要Asp.netMVC框架支持(The main functions are as follows: 1 a fast query of the purchase price of the products, price and delivery unit. 2 quickly check the supplier s phone, in order to make a phone call to ask whether the goods are available. 3 can be sorted according to the field DB under the Sql2005 , can be added to Note: the system needs Asp.netMVC framework support)

通过IQmath计算交流电的电压有效值，电流有效值，电压平均值，电流平均，过零点，交流频率。通过测试比普通的浮点计算快10几倍。IQmath开根只需要52个周期，二普通开跟函数至少需要300多个周期。所以对于环路计算有非常搞得效率。
