在连续3个月的时间里，对进食固定成分的年轻谢尔曼雄性和雌性大鼠进行了随意饮水与食物摄入关系的每日观察，并特别注意了处理、体重和性别对这种关系的影响。实验前未处理的大鼠第1周的饮水量总是高于随后的趋势值，也高于之前处理过的大鼠。虽然水的摄入量随着体重的增加而增加，但这种依赖关系是轻微的（+.03 -）。体重增加0.05 ml/g)，而其依赖于食物摄入（摄入食物增加0.75 ml/g）。由于体重的增加速度快于食物的增加，与体重有关的水在每日总饮水量中所占的比例更大。虽然两种绝对摄取量都随着时间的推移而增加，但水的摄取量比食物的摄取量增加得更快。因此，水与食物的比例逐渐增加。这些……
Daily observations for 3 months on the ad libitum water-to-food-intake relationship were made on young Sherman male and female rats subsisting on a diet of constant composition, with particular attention being given to the influence on this relationship of handling, weight, and sex. The 1st-week values for water intake in rats not handled prior to experimentation were always higher than subsequent trends and higher than those for previously handled rats. Though water intake increased as body weight increased, this dependence was slight (+.03–.05 ml/g increase in body wt) as contrasted to its dependence upon food intake (+.75 ml/g increase in food ingested). Since the body weight increased faster than the increase in food, the portion of water related to body weight comprised the greater fraction of the total daily water intake. While both absolute intakes continued to increase with time, water intake increased at a greater rate than food ingestion. Thus, the water-to-food ratio gradually increased. These ...
