But more important, scientists and engineers have since compared the weight of a volume of material with an equal volume of water and called the result Specific Gravity.
但更为重要的是，科学家和工程工程师们一直将一定体积的材料和同体积的水相比较，把比较的结果称之为“比重”。
Can you tell me how much water, how much salt, how much of each different element there should be in your blood to maintain its proper specific gravity if you are leading an ordinary sedentary life?
你知道一个人在坐着不动的时候，血液中应该含有多少水份、多少盐分和多少其他元素来维持一定的比重吗？
A check of urine specific gravity at the time of admission of an acute asthmatic will invariably show a state of severe water retention with high urinary specific gravity.
此时检查急性气喘病患者的尿比重，将发现他们都处于水潴留与尿比重高的状态。
