目的探讨高血压及药物治疗对飞行员认知功能的影响。方法对13名无并发症的高血压飞行员和10名经降血压药物治疗后血压恢复正常的飞行员,进行闪光融合频率、多项反应时、空间位置记忆广度、注意力集中能力、警戒性等认知功能测试,并与年龄相近的13名健康飞行员对照。结果高血压组闪光融合频率、注意力集中能力、空间位置记忆广度分值均明显低于对照组(P<0.05、P<0.01和P<0.01),多项反应时中红、黄绿反应时间明显慢于对照组(P<0.01),警戒性作业总错误率明显高于对照组(P<0.01)。高血压治疗组与高血压组均有统计学差异(P<0.05、P<0.01)。结论患高血压病飞行员有不同程度的认知功能减退,在飞行人员医学鉴定时应予重视。

目的探讨飞行人员胆囊息肉患者组与健康飞行人员(对照组)胆囊排空功能的差异。方法对来院接受年度大体检的18例患有胆囊息肉的飞行人员及18例年龄、飞行机种、飞行时间相仿的健康飞行人员进行胆囊超声检查,分别于空腹状态下及脂餐后1 h测量胆囊最大长径、上下径、前后径,根据椭圆体公式计算空腹胆囊体积及脂餐后残余胆囊体积,计算胆囊排空率。比较两组之间胆囊排空率的差异。结果 PLG组18例,约占同期住院体检飞行人员(257例)的7.0%,总体上PLG组的胆囊排空功能显著低于正常对照组(P<0.05)。结论 PLG是飞行人员中的常见病,其发病可能与胆囊排空功能不良有密切关系。胆囊排空功能检查可以列为招飞体检及飞行员年度体检的常规检查项目。

The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.

A new approach for nonlinear adaptive control of turbine main steam valve is developed. In comparison with the existing controller based on ＂classical＂ adaptive backstepping, this method does not follow the classical certaintyequivalence principle in the design of adaptive control law. We introduce this approach, for the first time, to power systems and present a novel parameter estimator and dynamic feedback controller for a single machine infinite bus （SMIB） system with steam valve control. This system contains unknown parameters such as reactance of transmission lines. Besides preserving useful nonlinearities and the real-time estimation of uncertain parameters, the proposed approach possesses better performances with respect to the response of the system and the speed of adaptation. The simulation results demonstrate that the proposed approach is better than the design based on ＂classical＂ adaptive backstepping in terms of properties of stability and parameter estimation, and recovers the performance of the ＂full-information＂ controller. Hence, the proposed method provides an alternative for engineers in applications.
