水声通信面临的最困难的问题是多途干扰,其中自多途引起接收信号的幅度衰落,互多途引起接收信号的码间干扰,再加上海洋环境的高噪声背景、低的载波频率、极为有限的带宽以及传输条件的时间—空间—频率变化特性,使得通信过程十分困难。此外，水声通信试验的成本高，难度大，也为水声通信研究带来挑战。 本软件对水声信道的仿真研究很有帮助，可以产生声线图，冲激响应，声速图等仿真文件，结合Matlab画图工具绘制图像，对水声信道的模拟仿真很有帮助。(The most difficult problem faced by underwater acoustic communication is multi-path interference, which since multipath fading caused by the magnitude of the received signal, and mutual inter-symbol interference caused by multipath signal reception, plus the marine environment of high background noise, low carrier frequency , very limited bandwidth and transmission conditions of time- space- frequency characteristic such that the communication process is very difficult. In addition, the high cost of underwater acoustic communication experiment, difficult, and challenges for the study of underwater acoustic communication. This software is useful for simulation study of underwater acoustic channel can produce sound chart, impulse response, sound velocity diagrams simulation files, combined with Matlab drawing tools to draw the image of underwater acoustic channel simulation helpful.)

电动执行机构是连接控制器与执行器(阀门)的部件，从控制出来的是离散信号，经零阶保持器后成为一个方波 信号，值都是阶跃跳动，而阀门的实际工作是有一定的行程时间的，即实际上阀门是不可能实现阶跃跳动的，故此需要一个电动执行器，将控制器的阶跃信号变为连续变化信号，假定阀门的行程时间与阀门开度变化成正比。(Electric Actuator is connected controller and actuator (valve) parts, from the control out of the discrete signal by zero-order cage became a square wave signal, values are step-beating, but the actual work of the valve there is a certain amount of travel time, that is, in fact the valve can not be achieved step beat, and therefore need an electric actuator, the controller of the step change in the signal into a continuous signal, assuming that the valve and the valve travel time changes in direct proportion to the door opening.)
