            man top

                   Line 2 shows CPU state percentages based on the interval since the last refresh.
            
                   As a default, percentages for these individual categories are displayed.  Where two labels are shown below, those for more recent kernel versions are shown first.
                       us, user    : time running un-niced user processes
                       sy, system  : time running kernel processes
                       ni, nice    : time running niced user processes
                       id, idle    : time spent in the kernel idle handler
                       wa, IO-wait : time waiting for I/O completion
                       hi : time spent servicing hardware interrupts
                       si : time spent servicing software interrupts
                       st : time stolen from this vm by the hypervisor
            

            niced user process 表示优先级较高的用户进程。
