瑞士的和德国的几位研究人员,用氘的氧化物~2H_2O稀释法,测量了165名健康儿童的体躯成份,发现体躯的水份、瘦物质和脂肪物质是随年龄而变化的。 体水是用氘的氧化物稀释法测量的。接受测量的儿童都按2毫升99.8％的氘氧化物/千克体重的比率饮了氘的氧化物。饮了氘氧化物以后2—3小时内,不准儿童饮用任何液体。收集儿童在饮了氘的氧化物之后至少 Several Swiss and German researchers measured the body composition of 165 healthy children using the deuterium oxide ~ 2H2O dilution method and found that body weight of water, lean matter and fatty matter varied with age. Body water is measured by the deuterium oxide dilution method. Children who were measured drank deuterium oxide at a rate of 2 mL of 99.8% deuterium oxide / kg body weight. Within 2-3 hours after drinking deuterium oxide, do not allow children to drink any liquid. Collect children at least after drinking deuterium oxide
