Description: 这个文章和附件中的代码实现如何将OpenGL/MFC程序输出到 encapsulated postscript (EPS)和Windows enhanced metafile (EMF)文件格式。最终的目标是能够产生可以编辑、打印和展示的适量图形文件。
-* display a vrml 3D triangular mesh using OpenGL in a MFC MDI application,
* change the rendering options such as wire-frame, smooth shading, lighting and culling,
* export the rendering result of the current mesh to encapsulated postscript (EPS) format,
* export to Windows enhanced metafile (EMF) format through the clipboard,
* copy the rendered image to the clipboard using the DIB format,
* apply mesh subdivision using the uniform Loop subdivision scheme [1].

Description: 具有梯形反电动势的永磁同步电动机通常被称为无刷直流电动机，它具有结构简单、体积小、重量轻、效率高、高功率密度、启动扭矩大、惯量小和响应快等其它种类直流电机无法比拟的特性。采用电子换向器替代了传统直流电动机的机械换向装置，从而克服了电刷和换向器所引起的噪声、火花、电磁干扰、寿命短等一系列弊病。-With a trapezoidal back-EMF permanent magnet synchronous motor is often referred to as brushless DC motor, it has a simple structure, small size, light weight, high efficiency, high power density, starting torque, inertia, and other types of fast response dc can not match the characteristics of the motor. Electronic commutator DC motor instead of the traditional mechanical reversing device, thereby overcoming the brushes and commutator caused by noise, sparks, electromagnetic interference, short life and a series of ills.

Description: 电磁流量传感器是基于法拉第电磁感应定律而制成的，只是其中切割磁力线的导体不是一般的金属，而是具有一定电导率的液态流体或液固两厢流体。被测量的导电介质在磁场中作切割磁力线运动时，导电介质中会产生感应电动势，感应电动势由一对电极检测-Electromagnetic flow sensor is based on Faraday' s law of electromagnetic induction and made of only one conductor cutting magnetic field lines is not an ordinary metal, but has a certain electrical conductivity of the liquid fluid or liquid-solid hatchback fluid. Conductive medium being measured in the magnetic field movement for cutting magnetic field lines, conductive medium will be induced electromotive force, EMF detection by a pair of electrodes
