stripped leaf meaning in Chinese

去梗烟叶, 去中肋的烟叶

He rode now beside ilyin , between the birch - trees , stripping leaves off the twigs that met his hand , sometimes touching his horses side with his foot , handing the pipe he had finished to an hussar behind , without turning his head , all with as calm and careless an air as though he were out for a ride
现在他与伊林并马行进在白桦树中间，时而随手从树枝上扯下几片树叶，时而用脚磕磕马肚皮，时而把抽完的烟斗不转身就递给身后的骠骑兵，如此从容不迫，一幅无忧无虑的样子，好像他是出来兜风似的。
