介绍了交流调速及其相关技术的发展现状和发展趋势，以及交流调速系统的主要控制策略。选用工业变频器用异步电机作为研究对象，利用坐标变换理论，分析了异步电机在三相静止坐标系、两相静止与旋转坐标下的电机基本数学模型及其矢量控制原理。(The present situation and development trend of AC speed control and its related technology are introduced, and the main control strategies of AC speed control system are introduced. The basic mathematical model of the motor and its vector control principle are analyzed by using the coordinate transformation theory, which is based on the three-phase stationary coordinate system, two-phase stationary and rotating coordinates.)

这是我设计自动化的系统的原理图及PCB,里面包含电机、电磁阀、光耦模块，继电器，传感器、单片机系统(This is my design automation system schematics and PCB, which contains the motor, solenoid valve, optocoupler module, relays, sensors, microcontroller system)

粘弹性地震波的衰减不仅与传播时间有关，而且与子波的频率、速度场的分布、射线路经、地下构造展布都有关，因此，仅仅利用反Q滤波对粘弹性的吸收和频散做一维补偿不能完全的恢复地震波长的本来特征。(Viscoelastic seismic wave attenuation is not only associated with the propagation time, and and wavelet frequency distribution of the velocity field, the ray path, subsurface structures spread are related, using only inverse Q filtering viscoelastic absorption and dispersion do The one-dimensional compensation can not completely restore the original features of the seismic wavelength.)

说明：  本文主要论述了电力系统中的铁磁谐振产生的主要原因、发生谐振时的现象、危害以及消除谐振的办法。(This paper discusses the main reason of the power system in the ferromagnetic resonance, the phenomenon of resonance occurs, hazards and the elimination of the resonant way.)

DHCP（Dynamic Host Configuration Protocol，动态主机配置协议）是IETF为实现IP的自动配置而设计的协议，它可以为客户机自动分配IP地址、子网掩码以及缺省网关、DNS服务器的IP地址等TCP/IP参数。了解DHCP工作过程可以帮助我们排除有关DHCP服务遇到的问题。DHCP 协议是基于UDP层之上的应用，本文结合抓报所得数据分析DHCP协议实现原理(DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is the IETF protocol designed for automatic configuration of IP for the client, it can automatically assign the IP address, subnet mask, and default gateway, DNS server IP addressand other TCP/IP parameters. Understanding of the DHCP the work process can help us to rule out problems encountered about DHCP service. The DHCP protocol is based on the the UDP layer on top of the application, combined with a grasp reported income data analysis DHCP protocol implementation principle)
