SIMATIC S7-1200 三路步进电机控制器 (Set 2)

用于风电场区域的风速多步预测问题。模型基于ARIMA，通过数据预处理、进行建模，并使用我国山东省两个风电场的历史风速数据进行测试和分析。结果表明，模型的统计误差小。(Multi-step wind speed prediction in wind farm area. The model is based on ARIMA, through data preprocessing, modeling, and using historical wind speed data of two wind farms in Shandong Province of China to test and analyze. The results show that the statistical error of the model is small.)

说明：  此代码为matlab寻优测试代码，并且画出进化图，只要把目标函数带入测试即可。(This code is matlab optimization test code, and draw the evolution diagram, as long as the objective function into the test.)

此算术表达式能够在程序运行时根据输入的变量大小和算术表达式动态解析表达式()

vc++将汉字转换成拼音的程序源代码，非常有意思，它不单纯转换为拼音，而且还可以设置分隔符，按规则转换：全部转换成大写、全部转换成小写、将首字母大写，还可以转换为现在流行的拼音首字母简写，也就是只取拼音首字母，按大写或小写提取，看来确实非常有意思也非常实用哦。(vc++ will be converted into Chinese characters spelling the source code, very interesting, it does not simply converted to Pinyin, but also can be set separators in accordance with the rules of conversion: the conversion of all upper case, all converted to lowercase to uppercase the first letter, but also can be converted to Pinyin is now the first letter of the popular shorthand, that is, only the first letter of alphabet, based on extraction of upper or lowercase, it seems very interesting indeed Oh also very practical.)

说明：  pycamera,在python上的摄像头调用工具(pycamera,camera demo for python)

说明：  平面上排布不同旋转角的纳米天线产生不同几何相位调制用生成涡旋光(The vortex is generated by the different geometric phase modulation of the nanometer antenna with different rotation angles arranged on the plane)

New firmware gx 6605s

说明：  SMART GRID SYSTEM FOR PS

保铮的最新雷达成像原理，对于学习SAR的同志帮助很大。(the latest radar imaging principle, the SAR study Comrade great help.)

本程序演示了半满方式的AD卡数据采集系统的实现方式和具体应用-This procedure demonstrated a half-full way of the AD card data acquisition system realize the ways and specific applications
