从标准内核中您可以实现软实时功能，再执行一些额外的工作(内核补丁)您就可以构建硬实时应用程序。

You can get soft real-time performance from the standard kernel or, with a little more work (kernel patch), you can build hard real-time applications.

正如你看到的，RTSJ提供了范围非常广的功能，允许企业级应用程序可以混合运行非实时线程、软实时线程和硬实时线程。

As you can see the RTSJ provides a range of capabilities to allow an enterprise application to run as a combination of non real-time, soft real-time and hard real-time threads.
