Description: 从空格(ASCII码32)到~(ASCII码126)。表内的第一行与表头相同，下面的每一行都与上一行的内容相同，只是字符相左移动了一个位置。这样，下一行的最后一个字符与上一行的第一个字符相同。
为了进行文本编码，可以任意选择一个字符串，称之为编码字符串，也就是常说的密钥。为解释编码方法，我们假设密钥是Walrus，待编码的文本（即常说的明文）是：
Meet me in St. Louis
我们在待编码的文本之上重复书写上述密钥，使得其长度与待编码文本相同：
WalrusWalrusWalrusWa
Meet me in St. Louis
从上述两行文本中按列对应方式依次提取一个字符，可得到多个字符对：WM、ae、le等，这些字符对可用作上表的索引。这样，依次以这些字符对作为索引可从上表查到一系列字符，这些字符就构成了文本编码，即常说的密文。例如，第W行第M列队应得字符是%，因此编码的第一个字符就是%；第a行第e列对应的字符是G；第l行第e列对应的是R。依次进行上述查找操作，可以得到完整的密文
%Grgua=aVauGLol?eiAU
进行相反的操作就可对该文本解码。
编写编码/解码程序，可以对文本文件或键盘输入的字符串进行编码/解码，在选择编码解码后，需要提示用户输入密钥。

Character movement is a curator position. So, the next line of characters with a final party on the first character of the same. To text encoding, can choose an arbitrary string, the string as coding, which is often said that the key. To explain the encoding method, we assume that key is Walrus when coding the text (often said that an express) : Meet me in St..

Description: 水面无人艇(Unmanned Surface Vehicle)的航迹控制对提升无人艇艇载设备
侦察观测效果以及多任务作战能力具有十分ffi要的意义。由于受到风、浪、流等
干扰环境影响,水而无人艇将产生六自由度的操纵运动,具有很强的非线性和随
机性。这将致使无人艇的航向航迹及姿态控制具有一定的难度,因此需要对水面
无人艇建立六自由度操纵模型,更好地实现对无人艇的控制。
采用经典的MMG分离建模思想,依托浜本刚实提出的水平附体坐标系,建
立水面无人艇的六自由度操纵运动方程。分析无人艇艇体、桨、舵所受的流动动
力和力矩,分别建立流体惯性力模型、流体粘性力模型、螺旋桨推力模型及舵机
模型。
考虑海况和气象环境的影响,分析风、浪作用于无人艇上的T扰力。将随机
风简化为定常风,建、风的干扰力数孕模型 采用傅汝德-克茁洛火(Froude - Krylov)
假设,研究规则波中无人艇受到的T扰力,述立波浪的r扰力数学投型。
在数学模型的站础上述立?于MATLAB/Simulink的仿i t校型,并进行典型的
冋转试验,分别分析不同海况下的无人艇的问转情况。无人艇丨 丨主航行时,在不
同海况下,绘制出其航速及船摇炻的变化曲线。通过总结分析,推论出多种海况
-The course and track control of unmanned surface vehicle (USV) is important to
improve the observational effect of the recon reconnaissance equipment and the multi-
-mission operational capability. Because of the effects of wind, wave and flow, the
unmanned surface vehicle will produce six degrees of freedom movement which has
randomicity and nonlinearity. It is difficult of the course, track and attitude control of
unmanned surface vehicle, so six degrees of freedom movement model is built for the
better control of unmanned surface vehicle.
According to the classic MMG s separated modeling theory and the horizontal
body axes system which was developed by Hamamoto, this thesis describes a six
degrees of freedom motion equation of unmanned surface vehicle. Through analyzing
the hydrodynamic force and moment, the fluid inertia force model, the fluid viscous
force model, propeller thrust model and steering gear model are built respectively.
