这是西门子s7200的示例源代码，这是学习PLC编程的好示例-Siemens s7200 This is an example of source code, this study are examples of good PLC programming

说明：  交易模型系列Excel模板是Wind资讯依据Excel插件丰富的函数功能，结合VBA脚本编辑，实现量化交易的轻量级解决方案的演示。 目前，该模块用户可自由设定套利品种对以及套利上下限，模板实现盘中价差监控，触发信号后可一键下单或者自动下单。(The transaction model series excel template is a demonstration of a lightweight solution for quantitative transaction based on the rich functions of Excel plug-in and VBA script editing. At present, users of this module can freely set the arbitrage variety pair and the upper and lower limits of arbitrage. The template can monitor the intraday price difference, and can place an order with one key or automatically after the trigger signal.)

迷宫问题，可以自己设计迷宫，然后通过程序找到相应的出口。(You can design maze by yourself,then find the appropriate exit through the program.)

关于蒙特卡洛相关方法的MATLAB程序实现(MATLAB program implementation about Monte Carlo method)

说明了在 POSIX 系统 (Linux,Unix) 上使用 Unicode/UTF-8 所需要的信息. 在将来不远的几年里, Unicode 已经很接近于取代 ASCII 与 Latin-1 编码的位置了. 它不仅允许你处理处理事实上存在于地球上的任何语言文字, 而且提供了一个全面的数学与技术符号集, 因此可以简化科学信息交换. -Described in the POSIX system (Linux, Unix) required the use of Unicode/UTF-8 information. In the near future several years, Unicode is already very close to replace the ASCII and Latin-1 encoded the location of the. It is not only permit In fact you deal with deal with on Earth exists in any language, but also provides a comprehensive mathematical and technical symbol set, it can simplify the exchange of scientific information.

数模中求解偏微分方程时，在已知数据的基础上进行线性插值拟合。利用差分法求解该模型，先用网格划分区域，对 区域内部节点做泰勒展开。对偏导数进行离散化处理。(tthe solution to the PDE problem in mathematical modeling)
