Spectroscopic method for measuring isotope gas 13 Co2/12Co2 in human body按照本发明,人体呼出气体中所含的浓度比 According to the present invention, the concentration of human exhaled gas contained ratio森正昭久保康弘筒井和典
凡涉及人体“酸碱平衡”的教科书,都认为生物氧化产生的CO2可与H2O结合成H2CO3,是机体代谢产 生最多的酸。然而CO2在人体内的主要存在形式是碱性物质HCO3 -,在血液中HCO3 -浓度比H2CO3高20倍,24 h由 CO2转化的HCO3 -是血液HCO3 -含量的110倍。CO2维持了血液HCO3 -的恒定,
Abstract:The carbon dioxide released by human body is used as a tracer gas. By measuring the average concentration of each measuring point, and analyzing the relative error of the average concentration one by one, the most suitable test point, namely the center of the room, is found. The ve...

Question: Describe the movement of diffusion regarding CO2and O2in the lungs and the blood at the alveolar capillaries. Cellular Respiration: The cells of our body produce energy (stored as ATP) primarily via a process called cellular respiration. In cellular...
Conclusion, indoor carbon dioxide concentration is too high will make people feel discomfort, health has certain effect to the human body, fresh air system can ensure the indoor concentration of carbon dioxide has been in a low state. There are fresh air system of the house will be the ...
Surprisingly little research has been devoted to establishing the underlying statistical relationship between human activities and CO 2 emissions. In this paper, we explore the nature of the relationship between global population growth and CO 2 emissions by employing the test of causality developed by...
