说明：  实现数据链路层的协议，属于计算机网络的协议实现(Implement the protocol of data link layer, a protocol implementation that belongs to a computer network)

说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)

能实现椭圆曲线密码的加密解密过程，功能齐全，易于实现(Can realize the elliptic curve cryptography decipher process, function is complete, easy to realize)

说明：  C#使用的modbus通讯协议编程。。真实可靠有用(C_modbus communication protocol programming. True, reliable and useful)

在IEEE - 1588系统中, LXI设备把它们的时钟与一个公共意义上的时间(网络中最精确的时钟)相同步。通过对时钟的同步, LXI仪器 就能在规定时间开始(或停止)测量/激励,同步测量或输出它们的信号,而不需要触发线,并为所有事件和数据加时戳。-In the IEEE- 1588 System, LXI device clock them with a public sense of the time (the network the most accurate clock) phase synchronization. Through the clock synchronization, LXI instruments can be in a specified time start (or stop) measurement/incentive, synchronous measurements or output their signals without the need for the trigger line, and for all the events and data plus timestamp.
