A method for carrying out terminal management based on EPON includes connecting unit management system on optical line terminal based on EPON and setting up network management channel between them and between optical line terminal and each network terminal, carrying out analysis on message by optical line terminal when network management protocol message is sent to optical line terminal by unit management system, retransmitting message to network terminal by set up operation-maintenance channel when network protocol message is aimed at network terminal and retransmitting message reported from network terminal to unit management system by optical line terminal.

一种对基于EPON进行终端管理的方法，在基于EPON的光线路终端上连接设备管理系统，在它们之间建立网络管理通道，并在光线路终端和各网络终端之间建立承载在操作管理维护协议层上的网络管理通道；设备管理系统向光线路终端发送网络管理协议报文时，光线路终端对该报文进行解析，如果是针对网络终端的网络管理协议报文，则将该报文通过所建立的操作维护通道转发给该网络终端；网络终端向设备管理系统上报的消息，由光线路终端转发给设备管理系统。

使紧接阀座出口端的通道急剧扩大可防止阀体壁和管壁遭受气蚀损坏，对用于水厂中的针形阀，其扩大腔室的直径为管径的1.5倍，包括出口退拔在内的通道长度为管径的8倍时，可避免遭受气蚀。

A software high frequency channel simulation algorithm is presented aiming at the characteristics of HF channel which has unrepeatability, multipath and fading.

针对短波信道不可逆性、多径以及衰落等特点，提出了一种纯软件的短波信道仿真算法。

A hydraulic resistance instrument composed by two pressure transducers was used to measure the hydraulic resistance across the two kinds of channels. The impedance on both channels was measured by a four electrodes impedance instrument with 5kHz constant current. A vibration generator was put on one set of the channel to produce about 50Hz sound waves. The signal was detected by a crystal pickup on the other set of the channel to examine the transmission of the wave along the two kinds of channels.

使用双压力传感器流阻仪对两种通道的流阻进行测定；使用5kHz恒流四电极方法对两种通道的阻抗进行测量；使用激振器在通道的一端产生一个约50Hz的振动，在通道另一端用晶体拾音器检测振动信号，对两种通道的声音传导特性进行了测定。
