Boost电路小信号建模全过程！！！！十分详细！！！(Boost circuit small signal modeling all process!!!!! Very detailed!!!)

说明：  Code with C++, Concurrent programming

说明：  锁相的意义是相位同步的自动控制,能够完成两个电信号相位同步的自动控制闭环系统叫做锁相环,简称PLL. 3种软件锁相的方法：指针归零法，先调频后调相法，调频调相同时进行法。(The meaning of phase-locked is the automatic control of phase synchronization. The automatic control closed-loop system that can complete the phase synchronization of two electrical signals is called PLL The 3 method of software phase-locked: pointer to zeros, first phase modulation after frequency modulation, frequency modulation phase modulation at the same time.)

基于网络的计算机处理技术，与集中式相对应。由于个人计算机的性能得到极大的提高及其使用的普及，使处理能力分布到网络上的所有计算机成为可能。分布式计算是和集中式计算相对立的概念，分布式计算的数据可以分布在很大区域(Network-based computer processing technology corresponds to centralized. As the performance of personal computers has been greatly improved and the popularity of their use, it is possible to distribute processing power to all computers on the network. Distributed computing is a concept opposite to centralized computing. The data of distributed computing can be distributed in a large area.)
