REChromeOS怎么不是操作系统了阿，它不过是用了浏览器作UI而且。 操作系统有定义的，虽然不是特别严格的定义 “Chrome OS is an operating system designed by Google that is based on the Linux kernel and uses the Google Chrome web browser as its principal user interface. As a result, Chrome OS primarily supports web applications” --https://en.wikipedia.org/wiki/Chrome_OS
