嗯嗯额

说明：  柱子P1、P2的位置是可以随意摆放的，机器人R沿黑线方向行走。利用6号和9号声纳来测距离（这两个声纳的测量角度比较大，可以很好号的实现设计要求），6号声纳测机器人与P1的距离d1，9号测机器人与P2的距离d2。当机器人行走到某处时，两个声纳分别测到的距离差d1-d2小于20mm，并且d1、d2都小于600mm时，则判断为此时机器人行走到了P1与P2的中间，机器人转90°，沿两柱子的中心线继续向前走。(Columns P1, P2 position can be arbitrarily placed, the direction of the robot R to walk along the black line. 6 and 9, using sonar to measure the distance (the measurement point of view the two sonar relatively large, a good number can meet the design requirements), 6 sonar distance measuring robot and P1 d1, 9 号 testing machine Man and P2 distance d2. When the robot to walk somewhere, two sonar distances were measured to the difference d1-d2 is less than 20mm, and d1, d2 is less than 600mm, then determine the robot to walk at this time to the middle of P1 and P2 the robot turn 90 °, along the center line of the two pillars to continue to move forward.)

密码锁,尚不能修改密码，技术味道，请见谅，望大家加以改进，期待(elec_code_lock)

说明：  一个用MATLAB实现的二阶系统的编程,想望对下载的人有用(this is a small file for two order styem by MATLAB ,I hope it will be useful to your.)

关于用户自定义标量输运（UDS)中非定态情况下的代码源项，主要用于非稳定流动的物质输运的耦合(On the code of the user-defined scalar transport (UDS) Central Africa steady state case the source terms, mainly for non-steady flow of the coupling of mass transport)

此卫星定位系统通信是没有任何问题的，如果通信不了，那就是你硬件问题了。(The GPS communication is no problem, if can t communicate, that is your hardware problems)

用于没有串口通信硬件的单片机，通过使用IO来模拟Uart的通信应用程序(For no hardware serial communication of single chip microcomputer, through the use of IO to simulate Uart communication applications)

本书详细介绍了基于近场测试数据的逆散射问题的相关知识及其具体应用，这是近场问题的一个很好的例子，在人们都关注高频远场问题的背景下，提出近场的问题，对于计算电磁学的发展很有启发意义，我们的工程实际中，除了高频远场的应用外，低频近场也占有很大的份额，基于进场的反演是一个新兴的课题，需要我们共同去研究！(Book introduced in detail based on near field test data of the inverse scattering problem related knowledge and its practical application, this is a very good example of near field problems, people are concerned about the background of far field problem of a high frequency in the, near field is proposed, for the development of electromagnetism calculation is instructive. In the actual engineering, in addition to the high-frequency far field of application, low frequency near-field also occupies a large share of, based on the inversion approach is a new and developing subject, we go to study!)

说明：  智能搜索组合框，用VC实现，最新源码。有相关需要的朋友值得(portfolio Intelligent Search box, with VC, the latest source. A related need to look at the merits of a friend)

说明：  三端稳压可调集成芯片．应用很广，可当制作各种类型的稳压源(Three-terminal adjustable regulator ICs. Application is very broad, can be produced when the source of all types of regulators)
