本文的主要目的是用标记水和漠化物稀释法测量高原人体内水的平衡及其分布，试图找出急性高山病（AMS）与其的关系、到达海拔4350m前4天和到达4天后，测量了受试者的水摄人量、水总排出量和尿以及排泄物中的水排出量。两个间隔的开始和结尾．又测量了体液总量（TBW）和细胞外液 The main purpose of this paper is to measure the water balance and its distribution in high altitude human body by labeled water and desertification dilution method. In order to find out the relationship between acute mountain sickness (AMS) and it, four days before reaching 4350m and four days after reaching Subjects’ water intake, total water excretion and urine as well as excretion of water excreted. The beginning and end of two intervals. The body fluid volume (TBW) and extracellular fluid were also measured
