Air-feeding sleeves with considerably higher turbine torques are rejected and probably reworked . 涡轮力矩相当高的馈气套简应予退回，或许还得重新加工。
2.
An increase in the specific work and cycle efficiency of gas turbines can be achieved through higher turbine entry temperatures . maintaining adequate life at these high temperatures requires the development of materials and efficient cooling methods 提高涡轮发动机效率的重要途径是提高其入口温度，而高温下涡轮发动机的寿命取决于相关零部件的材料特性和冷却方法的效率。
