c#项目工具 坐标转换 WGS84 北京54 西安80 都可

说明：  用列文伯格-马夸尔特法(Levenberg-Marquardt)进行计算，该算法既有高斯-牛顿法的局部收敛性，又具有梯度下降法的全局性。(The Levenberg-Marquardt method is used for calculation. This algorithm has both the local convergence of the Gauss-Newton method and the globality of the gradient descent method.)

lte中turbo编译码的源代码，使用c语言开发，可用(turbo encode and decode)

这是一个超声在金属中传播的仿真案例，通过COMSOL仿真软件实现的。(This is a simulation of the propagation of ultrasound in metals,realized by COMSOL simulation software.)

说明：  使用STC89C52单片机实现对PGA2311和CD4052的控制，进而实现对功放音量的控制。(The control of PGA2311 and CD4052 is realized by using STC89C52 single chip computer, and then the volume of power amplifier is controlled.)

此款软件可以实现测量点转面，这个面可以在arcgis中直接使用，是arcgis的视频文件格式。。。

he rotor/load angle is the angle between induced emf & terminal voltage in a 3-phase alternator & also the angle between rotating vectors of stator & rotor fluxes. Torque produced directly depends upon this angle.
