D 不可中断 Uninterruptible sleep (usually IO)
R 正在运行，或在队列中的进程
S 处于休眠状态
T 停止或被追踪
Z 僵尸进程
W 进入内存交换（从内核2.6开始无效）
X 死掉的进程

< 高优先级
N 低优先级
L 有些页被锁进内存搜索
s 包含子进程
+ 位于后台的进程组；
l 多线程，克隆线程 multi-threaded (using CLONE_THREAD, like NPTL pthreads do)

这个可以在 man ps 中查找 :PROCESS STATE CODES 可以看到这个解释:

PROCESS STATE CODES
   Here are the different values that the s, stat and state output specifiers (header "STAT" or "S") will display to describe the state of a process:

            D uninterruptible sleep (usually IO)
            R running or runnable (on run queue)
            S interruptible sleep (waiting for an event to complete)
            T stopped, either by a job control signal or because it is being traced
            W paging (not valid since the 2.6.xx kernel)
            X dead (should never be seen)
            Z defunct ("zombie") process, terminated but not reaped by its parent

   For BSD formats and when the stat keyword is used, additional characters may be displayed:

            < high-priority (not nice to other users)
            N low-priority (nice to other users)
            L has pages locked into memory (for real-time and custom IO)
            s is a session leader
            l is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
            + is in the foreground process group
