用简单易懂的图文方式阐释算法的奥秘，快速了解每个算法的使用场景、原理(Explain the mysteries of the algorithm with simple and understandable graphics and text, and quickly understand the scene and principle of each algorithm)

在开始一个路径前,先调用CDC类的成员函数BeginPath,然后调用一系列的输出函数,在完成绘制后,再调用CDC类的成员函数,在完成一个路径之后,就可以调用StrokePath来绘制该路径,这就是路径的基本用法.(at the beginning of a path, first call CDC category of members BeginPath function, then called a series of the output function, the complete mapping and then call CDC category of members function, the completion of a path, we can call StrokePath to mapping the path, This is the path the basic usage.)

类似电脑键盘组合按键触发的功能。利用51单片机实现。有两个独立按键，当把两个独立按键都按下后，蜂鸣器发出“滴”的一声后就停。直到松开任一个按键后，才能重新进行下一次的组合按键触发。(Similar to the function of the keyboard combination of keys. The use of 51 single chip microcomputer. There are two independent buttons, when the two independent buttons are pressed, the buzzer issued a drop of sound after the stop. Until after the release of any key, the next combination of keys can be re trigger. )

使用的排序算法，非常不错的思维，比较其他有较大优势(Sorting algorithm used, very good ideas, have greater advantages compared with other)

工程师和科学家们面临着用更少的时间建立复杂系统模型的需求，他们使用分布式和并 行计算来解决高性能计算的问题。这些分布式的环境由多处理器和多核计算机来实现。 Mathworks公司开发的分布式计算工具箱可以在多处理器计算环境中使用 MATLAB 和imulink 解决计算、数据密集型问题。可以使用该工具箱解决通过装配多个处理器包含几个单独工作单位或单个大型计算的问题。这些处理器可以驻留在一个多处理器计算机，或者，当工具箱配合 MATLAB 分布式计算引擎时，驻留在计算机集群上。(Engineers and scientists are facing with less time to build models of complex systems needs, they use distributed and parallel computing to solve the problem of high-performance computing. The distributed environment consists of multi-processor and multi-core computer to achieve. Mathworks Distributed Computing Toolbox, developed in multi-processor computing environment MATLAB and imulink solve computing, data intensive problems. You can use the toolkit to solve multiple processors by assembling several separate work units or containing a single large-scale computing problems. These processors can reside on a multi-processor computer, or, when the toolbox with MATLAB Distributed Computing Engine, it resides on a computer cluster.)

一、引言 在DOS系统下，在计算机应用培训中因培训要求不同， 对软件的要求也不同，由于学员的误操作，存放在硬盘上的软件和重要数据容 易被非法删除或受到损坏。对此，笔者通过对硬盘管理的深入分析和实践，总结出了在硬盘上备份、保护重要数据和软件的一种新的行之 有效的方法：建立多个PRI DOS 分区， 不同的培训要求使用不同的PRI DOS分区，在使用时同时只有一个PRI DOS 分区可供使用， 其余 PRI DOS分区均被隐含。-an Introduction DOS system, the computer application training due to different training requirements, the requirements of the software is different, because the participants Misoperation, stored on the hard drive software, and important data easily have been illegally removed or damaged. This writer drives through the management of an in-depth analysis and practice, summed up a hard drive backup, protection of important data and software in a new effective method : to create a number of PRI DOS partition, different training requirements using different PRI DOS partition, in the use of only one at the same time PRI DOS partition is available, the remaining PRI DOS partition were implied.

主要是针对codesys入门手册，对新手能起非常大的帮助。希望对大家能起作用(Mainly for codesys introduction manual, can be very helpful to novice.Hopefully that worked for you)

说明：  单片机驱动3310 lcd显示屏的c程序，单片机与屏的线路连接可以参见程序中的宏定义。程序写得很精简，但是很好用。(Microprocessor 3310 LCD display c procedures, SCM and the screen can see the line connecting the procedures macro definition. Very streamlined procedures, but is useful.)
