分别对不同行为类型的飞行学员、飞行教员和机务人员进行放单飞行前后 IL—2R 水平的检测,结果表明,无论 A 型或 B 型行为类型者,飞行人员飞行后 IL—2R 水平均显著减低 (P<0.001),而机务人员工作后 IL—2R 水平无明显变化。在高空飞行这一高应激源作用下,A 型行为飞行人员比 B 型行为者 IL—2R 水平下降的幅度更大;飞行学员比飞行教员 IL—2R 水平下降的幅度更大。结果提示高空飞行应激可使飞行人员的 IL—2R 下降,而 IL—2R 下降的幅度和行为类型及学习适应有关。 The levels of IL-2R were measured before and after single flight for pilots, flight instructors and crew members with different types of behavior respectively. The results showed that IL-2R levels in pilots were significantly decreased after flight (P <0.001), while IL-2R level did not change significantly after working crew. Under high altitude flight, the level of IL-2R decreased more in type A pilots than in type B pilots. Flight pilots dropped more than IL-2R in flight pilots. The results suggest that altitude flight stress can reduce the flight crew IL-2R, and the magnitude of IL-2R decline and behavior types and learning adaptation.
