E, " ejection starting " instruction message: in more program instruction ejection control systems of the network interconnection, every ejection escape seat
Chair can start ejection process, in " polymorphic " ejection of selection, " ejection starting " instruction message can make to own in network "
Line " seat enters ejection status；In " singlet " ejection, when minimum " online " seat of permission starts ejection, itself can only be made
Ejection；When in the starting ejection of middle priority " online " seat, itself and other lower priority seats will only be made to enter
Ejection status；Highest " online " the seat starting ejection of permission will equally make to own with " polymorphic " " online " ejection escape seat into
Enter ejection status.
