关于地震勘探中资料处理的一些基本编程，这里是关于射线追踪的一个小程序(Some basic programming on seismic exploration data processing, the purpose is to provide a good reference for everyone)

图像阈值分割技术在图像分割中具有重要的意义。遗传算法既可以对全局信 息高效利用，也减少了存储空间和计算量。利用遗传算法的优点，提出了一 种用改进遗传算法的图像分割的方法，可以将父代中适应度大的个体代替当前代 中的个体，保证了可以选出最优的个体。遗传算法是具有鲁棒性和自适应性的搜 索方法.通过实验对比，表明该方法具有快速、稳定分割的特点。(Image threshold segmentation technology is of great significance in image segmentation. Genetic Algorithms can be used for global information Efficient utilization of information also reduces storage space and computation. Based on the advantages of genetic algorithm, a new genetic algorithm is proposed. A method of image segmentation based on improved genetic algorithm can replace the current generation with individuals with large adaptability in the parent generation. The individual in the system ensures that the best individual can be selected. Genetic Algorithms are Robust and Adaptive Search The experimental comparison shows that the method has the characteristics of fast and stable segmentation.)

在微电网中综合考虑经济和环境两个目标，以各微源的运行上下限为约束条件，采用粒子群算法在matlab环境下进行了仿真，最后给出了微网各微源的最优机组组合方式和最佳电能交易计划。(The first establish micro multi-objective energy optimal operation model, taking into account both environmental and economic factors in the model, the operation of the various micro-source conditions and micro-grid electric power balance constraints, the establishment of a multi-objective function. To a typical micro-grid running instance As an example, the use of particle swarm optimization strategy and simulation in MATLABLAB environment,micro-source output for microgrid actual environmental economic dispatch .)

应用OFDM可以有效地对抗多径时延扩展。循环前缀不仅可以消除符号间干扰（ISI），还能消除子载波间干扰（ICI).本项目完整地仿真了OFDM系统。(Application of OFDM can effectively combat multipath delay spread. Cyclic prefix can not only eliminate inter-symbol interference (ISI), can eliminate Inter-carrier interference (ICI). This project a complete simulation of the OFDM system.)
