Abstract

Consumption of oxygen in rats was studied under conditions of the gas different ambient temperatures and pressure. A dependence was revealed between the neutral temperature and the high gas pressure. Mathematical model revealed an increase oxygen consumption at an increase gas pressure. The data suggest that the animal body temperature may be kept unaltered through an increased pressure of oxygen-nitrogen as a compensation of the heat transmission increased in an increased oxygen consumption.

摘要

在不同的环境温度和气压条件下研究了大鼠的氧气消耗情况。结果发现中性温度与高气压力之间存在相关性。数学模型显示随着气压升高氧气消耗增加。数据表明，动物体温可通过增加氧氮压力保持不变，作为对因氧气消耗增加导致的热传递增加的一种补偿。
