常见的并发模型有以下几种：

• 线程&锁模型
• Actor模型
• CSP模型
• Fork&Join模型

Go语言中的并发程序主要是通过基于CSP（communicating sequential processes）的goroutine和channel来实现。

Concurrency is an inherent part of the Go programming language. Concurrency is handled in Go using Goroutines and channels. We will discuss them in detail in the upcoming tutorials.
