Zusammenfassung:	A hybrid seal segment and a rotary machine (such as a steam or gas turbine) containing such hybrid seal segment. The machine has a rotor, a stator casing, and the hybrid seal segment. The annular hybrid seal segment has a circumferentially-extending channel between axially-spaced-apart first and second labyrinth-seal segments which are attached to a radially-outwardly located mounting block which is circumferentially offset from the labyrinth-seal segments. A brush-seal segment is positioned in the channel.
