1588高精度时间同步协议（PTP协议）的学习总结，希望对大家有所帮助(1588 Precision Time Synchronization Protocol (PTP protocol) study concluded, I hope to be helpful)

计算一维和二维表面粗糙度Ra，根据需要自行选择。(Calculate one and two dimensional surface roughness Ra, according to the needs of your choice.)

数学软件matlab可用于绘制各种二维和三维图像，介绍了matlab中的相关函数，附件中附带有各函数的例子，本人全都仿真过，全部可行(Mathematical software matlab can be used to draw a variety of two-dimensional and three-dimensional images, presented in the correlation function matlab, annex with examples from various functions, I have all simulation before, all feasible)

一天文学家要确定一棵小行星的运动轨道，他在其轨道内建立了以太阳为原点的直角坐标系，由开普勒第一定律知小行星的运动轨道为一椭圆，试确定行星的运动轨道。(One day in literature to determine the orbit of an asteroid, he set up in its orbit to the sun for the origin of the coordinate system, by Kepler s first law of motion track known asteroid is an ellipse, the orbits of planets.)

说明：  　本文在简要介绍了MA TLAB 和BP 网络的基 础上, 详细论述了在MA TLAB611 中, 如何利用其提供的神经网络工具箱实现BP 网络的设计, 最后给出了一个BP 网络的设计实例。 (This paper briefly introduced the MA TLAB and BP network based on the detail in the MA TLAB611, how to use its neural network toolbox provided realize the design of BP network, and finally gives a design example of BP network.)
