本文应用C语言编写，应用文档存储数据，基本的增删改查都在上面(The basic additions and deletions are all above.)

说明：  根据此算法可以将补偿函数与刘维尔分数阶导数相结合，则可以得出高精度的caputo分数阶导数。(According to this algorithm, the compensation function can be combined with the Liouville fractional derivative, and the Caputo fractional derivative with high accuracy can be obtained.)

KDM is an open source combat log parser for Aion Online and much more than a damage meter.

三相PFCmatlab仿真，双环控制，对于初学者有很好的参考价值(Three-phase PFCmatlab simulation, double loop control, for beginners have a good reference value)

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)

永磁同步电机自建模型仿真，此自建模型是基于dq轴的永磁同步电机，希望给初学自建烦琐子系统的同仁有点参考价值(self PMSM model simulation, the model is based on self-dq axis of permanent magnet synchronous motor, hope for self-learning cumbersome subsystem colleagues a bit reference value)

another incremental change is made to the new solution, and so on until no further improvements can be found.
