# 基于共享变量的并发

前一章我们介绍了一些使用goroutine和channel这样直接而自然的方式来实现并发的方法。然而这样做我们实际上屏蔽掉了在写并发代码时必须处理的一些重要而且细微的问题。

在本章中，我们会细致地了解并发机制。尤其是在多goroutine之间的共享变量，并发问题的分析手段，以及解决这些问题的基本模式。最后我们会解释goroutine和操作系统线程之间的技术上的一些区别。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://yar999.gitbook.io/gopl-zh/ch9.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
