There is a special process, the Kernel process, whose threads run at supervisor privilege level. This process normally contains two threads.
有一个特殊的进程，内核进程，它的线程运行在超级用户级别。这个进程通常包括两个线程。
In this model, an arbitrarily large number of user-level threads is multiplexed onto a lesser number of kernel execution vehicles. Kernel execution vehicles are also known as virtual processors.
在这个模型中，任意多数量的用户空间线程复用少量的内核执行对象，内核执行对象即为虚拟处理器。
Many modern UNIX operating systems implement a many-to-few model when mapping user-level threads to kernel entities.
很多现代的UNIX操作系统实现了一个多对一的模型，用来映射用户空间的线程到系统内核对象。
