说明：  利用winpcap编写的，直接从链路层收取数据帧的小程序，希望能有点用处。(use winpcap prepared directly from the data link layer frame collection of small procedures in the hope that this will usefulness.)

贪婪随机自适应搜索法(GRASP)，使用随机化的最小最小完成时间算法来产生问题的初始解,再通过变邻域下降算法来改进这个解。(Greedy randomized adaptive search method (GRASP), the minimum use of randomized algorithm to generate the minimum completion time of the initial solutions of the problem, and through the variable neighborhood descent algorithm to improve the solution.)

这是跳频的源程序,我的毕业设计做的,希望对大家有帮助和启发(This is the source frequency hopping, I graduated from the design done, and I hope to be helpful and enlightening)

在simulink里如何精确建模－好文推荐 Building Accurate, Realistic Simulink Models By Seth Popinchalk An accurate system model is one that performs as expected and produces the desired results. To achieve this level of accuracy you must have a clear modeling goal. For example, will the model be used strictly for simulation, or for generating embedded C code?? This article describes five modeling techniques that can help ensure accuracy: Select the right modeling approach Know your system, understand its dynamics Monitor fo (How accurate modeling in simulink- good text recommended)

基于ANSYS APDL二次开发的航电设备的动力学扫频分析，载荷输入条件为交越频率以下为恒定位移，交越频率以上为恒定加速度。我将加速度输入转换为位移输入，将位移和加速度两段输入载荷统一按照位移载荷输入，将位移存入表数组，利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组，并循环加载计算，实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)
