表面张力在生活现象中的应用分析

Case Analysis of the Application of the Surface Tension in the Daily Life

表面张力是液体的重要性质之一。毛细现象是浸润液体在细管中升高或不浸润液体在细管中降低的现象。它在日常生活和生产中都有着广泛的应用。植物的根茎把地下水输送到茎、叶,人类和动物在呼吸过程中,氧气和二氧化碳在肺泡处的交换,人或动物的血管中混合气泡的危害等,均可用液体的表面张力给以准确的解释。

Surface tension is one of the important properties of liquid. Capillarity refers to the increasing of the infiltration liquid and the decreasing of the non-infiltration liquid in the tubule, and it can be applied extensively in the daily life and production. The roots of plants transfer the underground water to the stems and leaves. The surface tension of liquid can give accurate explanation to the exchange of oxygen and carbon dioxide in the pulmonary alveoli in the process of breathing of human beings and animals, and the harm of the mixed air bubble in the blood vessel of the human beings and animals.
