<h2 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h2><p>论文（Paper）通常是新技术、算法、编程方法或软件工具的首次公布。通过阅读论文，我们可以了解最新的技术进展，保持自己的技能和知识是最新的。<br>同时，论文提供了对特定主题深入理解的机会。它们通常包含详细的理论分析和实验结果，这有助于深入理解某个概念或技术。但是，如何高效地阅读论文是一项关键但很少有人谈论的技能。刚开始大部分人自己通过试错来学习，但常常被挫败感所劝退。本文介绍一种阅读论文的方法——<strong>三遍阅读法</strong>。</p>

<h3 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h3><p>Goroutines 是 <a href="https://go.dev" target="_blank" rel="noopener">Go</a> 语言主要的并发原语。它看起来非常像线程，但是相比于线程它的<strong>创建和管理成本很低</strong>。Go 在运行时将 goroutine 有效地调度到真实的线程上，以避免浪费资源，因此您可以轻松地创建大量的 goroutine（例如每个请求一个 goroutine），并且您可以编写简单的，命令式的阻塞代码。因此，Go 的网络代码往往比其它语言中的等效代码更直接，更容易理解（这点从下文中的示例代码可以看出）。</p>
<p>对我来说，goroutine 是将 Go 这门语言与其它语言区分开来的一个主要特征。这就是为什么大家更喜欢用 Go 来编写需要并发的代码。在下面讨论更多关于 goroutine 之前，我们先了解一些历史，这样你就能理解为什么你想要它们了。</p>
