PIC 18F4550 BASIC LED CODE

说明：  光谱数据预处理 超级全 都可以用 自己用的(Spectrum data preprocessing)

由于快速性的要求，空中对准在大失准角下进行.仿真结果证实了该方法的可行性。(Due to the rapid nature of the request, the air at the angle in the inaccurate manner. Simulation results show the feasibility of the method.)

说明：  PSIM练习手册，非常详细，适合入门PSIM。(PSIM exercise manual, very detailed, suitable for beginners to PSIM.)

双重差分估计 双重差分模型（difference-in-difference，DID）近年来多用于计量经济学中对于公共政策或项目实施效果 的定量评估。 通常大范围的公共政策有别于普通科研性研究，难以保证对于政策实施组和对照组在样本分配上的完全随机。非随机分配政策实施组和对照组的试验称为自然试验（naturaltrial），此类试验存在较显著的特点，即不同组间样本在政策实施前可能存在事前差异，仅通过单一前后对比或横向对比的分析方法会忽略这种差异，继而导致对政策实施效果的有偏估计。(Quantitative evaluation of policy or project implementation effect. Generally, a wide range of public policies is different from general scientific research, and it is difficult to ensure that the sample allocation for the policy implementation group and the control group is completely random. The non-randomly assigned policy implementation group and the control group are called natural trials, which have significant characteristics, i.e. there may be prior differences between the different groups of samples before the implementation of the policy, and this difference will be ignored only through a single pre-and post-comparison or horizontal comparison analysis method, which leads to the policy. Biased estimation of implementation)

采用卡尔曼滤波方法的目标跟踪程序，很好用(It realizes the upload and download of network files. It is easy to use the target tracking program based on Kalman filter, and it is easy to use.)

简易数字示波器MATLAB实现，我自己写的，非常简陋，练习程序，还望见谅(Simple digital oscilloscope MATLAB implementation, I wrote it myself, very simple, exercise procedures, but also look forward to forgive me.)

说明：  蚁群算法 含有ACO ASO等很多 还有一篇论文(Ant colony algorithm)

在VC环境下，基于arcobject开发的地理灾害模块-in VC environment, based on the geographical arcobject development module disaster
