说明：  wp-postviews汉化版_浏览次数统计插件(The plug-in can count the number of visits to each article. According to the number of visits, it can display the hottest or the weakest rankings of articles in history. The scope of the display can be all articles and pages. When the plug-in is enabled, it automatically generates a small tool in the appearance-gadget. You can drag it to the sidebar to build a reading ranking and a popular collection waiting column.)

采用双曲线交汇进行长基线定位，误差源为测距误差的仿真图(the long baseline positioning is carried out by the double curve intersection, and the error source is the simulation diagram of ranging error.)

python学习资料，办公自动化操作，提高办公效率(Python learning materials, office automation operation, improve office efficiency)

说明：  变分模态分解的整体框架是变分问题，使得每个模态的估计带宽之和最小，其中假设每个“模态”是具有不同中心频率的有限带宽，为解决这一变分问题，采用了交替方向乘子法，不断更新各模态及其中心频率，逐步将各模态解调到相应的基频带，最终各个模态即相应的中心频率被一同提取出来(The whole framework of variational mode decomposition is variational problem, which makes the sum of the estimated bandwidth of each mode minimum. It is assumed that each "mode" is a finite bandwidth with different center frequencies. To solve this variational problem, the alternating direction multiplier method is used to update each mode and its center frequency continuously, demodulate each mode to the corresponding fundamental frequency band step by step, and finally each mode is called the first mode The corresponding center frequencies are extracted together)

说明：  利用Python，使用Arima模型对时间序列进行建模预测，结果中包含原始数据、建模全部代码以及预测结果可视化。(Using python, ARIMA model is used to model and predict time series. The results include raw data, modeling code and visualization of prediction results.)

这个是工程师应该掌握的20个电路，希望大家可以了解参考一下，谢谢！(This is the engineer should master 20 circuit, I hope you can understand the reference, thank you!)
