说明：  ARIMA整合移动平均自回归模型，时间序列预测分析方法之一，可用于股价预测。(ARIMA integrates moving average autoregressive model and time series forecasting analysis method, which can be used for stock price forecasting.)

very helpful for those who have initiated research

说明：  单相全桥双极性逆变器，可以用来学习、仿真双极性控制(single phase full bridge inverter, bipolar)

说明：  常规波束形成与最小方差无畸变算法性能对比（CBF、MVDR）(Performance comparison between conventional beamforming and minimum variance distortionless algorithm CBF MVDR)

说明：  abaqus中用fortran编写的热源子程序（双椭球）(Subroutine of heat source (double ellipsoid) written by Fortran in ABAQUS)

三相桥式全控整流电路仿真，使用晶闸管进行三相桥式全控整流电路仿真。(Three-Phase Full-Bridge Controlled Rectifier)

说明：  状态空间Boost建模，用增广系统进行状态反馈控制恒压(The state space boost model is built, and the augmented system is used to control the constant voltage)

说明：  混合粒子群求解TSP问题，重新定义了离散粒子群算法DPSO的速度和位置公式,使其适宜求解离散问题.针对DPSO易早熟,收敛慢的缺陷,建立局部极小区域的扰动机制,在结合局部搜索算法PSEC后,提出了一种混合离散粒子群算法HDPSO.(Hybrid particle swarm optimization for TSP)

计量模型，garch，var，用于建立各类模型，评估，roc等等(Econometric models, garch, var, used to build various models, evaluations, roc, etc.)

说明：  用MACCORMACK方法求解一维LAVAL管亚音速流动(solve one dimensional laval tube with the method in maccormack)
