温度对于人类生活、动植物生长和工农业生产都至关重要。人类有必要对环境和物体的温度进行经常的测量。最常用也是人们最熟悉的测量温度的仪器是玻璃液体温度计。它是德国物理学家华伦海特发明的,1709年他发明了酒精温度计,1714年又发明了水银温度计。在一根玻璃细管的一端有一个玻璃小球,当被测物温度升高或降低时,小球内的液体膨胀或收缩,促使细管内的液体柱伸长或缩短。人们观察此液体柱的长短,就可以知道温
Temperature is vital to human life, the growth of plants and animals, and the production of agriculture and industry. It is necessary for humans to make constant measurements of the temperature of the environment and objects. The most commonly used and most familiar instrument for measuring temperature is the glass liquid thermometer. It was invented by the German physicist Warren Hight, in 1709 he invented the alcohol thermometer, and in 1714 invented the mercury thermometer. At one end of a glass tube there is a glass bead that expands or contracts as the temperature of the analyte rises or falls, causing the column of liquid within the tube to elongate or shorten. People observe the length of the column, you can know the temperature
