Instead, they had their eyes glued to the cockpit instrument panel, which showed key information such as airspeed, altitude, Angle of flight, and fuel and oxygen supply.

相反，他们粘在驾驶舱仪表板，这表明，如空速，高度，飞行角度的关键信息，以及燃料和氧气供应他们的眼睛。

Conclusion: it can prolong the time of oxygen supply and improve mental performance to inhaling liquid oxygen at high altitude.

结论：吸入液氧能延长供氧时间，是提高高原人体运动能力和抗疲劳的理想措施。

Conclusion: Installing an oxygen-enriched room at high altitude is an ideal way to supply oxygen, which may improve human body energy metabolism and reduce physical fatigue.

结论：高原富氧室能增强机体能量代谢，减轻体力性疲劳，是一种较为理想的高原供氧途径。

To digress for a moment, it was biologist Felix Meerson who showed that high-altitude chambers where oxygen supply is limited, triggers an adaptive response that produces humans with profound mental capabilities and resistance against disease.
