Abstract

We are devoted to the physical analysis of the habitat area of warm-blooded organisms – humans and many mammals. For this purpose, the establishment of equilibrium distribution of carbon dioxide in aqueous solutions of salts in contact with atmospheric air starting from some time is investigated. More precisely, the relaxation time of carbon dioxide, as a function of temperature and pH, is investigated. It is found that the pH-relaxation time τS is a very nontrivial function of temperature, pH values, and NaCl salt concentration. It was assumed that the minimum value of pH relaxation time corresponds to the optimal rate of physical processes in living matter. Using this selection principle and our experimental data, we have shown that the optimal temperature for human and mammalian life activity is close to To ≈ 37 °C. The lower and upper temperature limits for their possible activity are close to Tl ≈ 30 °C and Tu ≈ 42 °C, respectively. The optimal value of pHo, determined by the same selection principle, also becomes true if supplemented by the influence of albumin and other proteins.

温血生物生命活动的主要参数与盐水溶液性质的关系
& lt; abstract>我们致力于温血生物(人类和许多哺乳动物)栖息地的物理分析。为此,研究了从一段时间开始与大气空气接触的盐水溶液中二氧化碳平衡分布的建立。更准确地说,研究了二氧化碳的弛豫时间作为温度和pH值的函数。发现ph -弛豫时间<斜体>τ<sub>S</sub></斜体>是温度、pH值和NaCl盐浓度的重要函数。假设pH弛豫时间的最小值对应于生物体内物理过程的最优速率。利用这一选择原则和我们的实验数据,我们已经表明,人类和哺乳动物生命活动的最佳温度接近于<斜体>T<sub>o</sub></斜体>≈37℃。它们可能活动的温度下限和上限接近于<斜体>T<sub>l</sub></斜体>≈30°C和<斜体>T<sub>u</sub></斜体>≈42℃。由相同的选择原理决定的<italic>pH</italic><sub>o</sub>如果补充了白蛋白和其他蛋白质的影响,则最佳值也为真。</p>& lt; / abstract>
