Abstract
Unacclimated pigeons were exposed to various simulated altitudes. Arterial and mixed venous blood gas levels were measured. At the highest altitude 9150m (Pb = 235 mm Hg) a remarkable degree of alkalosis was tolerated for several hours without ill effecrtant factor in the bird's ability to survive such altitudes.
摘要
未适应环境的鸽子被暴露于各种模拟海拔高度。测量了动脉血和混合静脉血的气体水平。在最高海拔9150米（气压 = 235毫米汞柱）时，鸽子能耐受显著程度的碱中毒数小时而无不良影响，这是鸟类在如此高海拔生存能力的一个重要因素。
