温度计的毛细管内液体柱常出现断节现象，为使断节与原液柱完全相接，我的修复方法是：1．断节小于2mm的温度计，将温度计平放，让液泡一端略低一些，直接用酒精灯烧断节，使断节汽化。然后将温度计移至火焰上方，用灯火烤液泡，使液柱缓缓上升，到达最高刻度线后立即离开火焰 Thermometer capillary liquid column often appear broken phenomenon, in order to make full connection with the original column of liquid column, my repair method is: Broken section is less than 2mm thermometer, the thermometer lay flat, so that slightly lower end of the vacuole, burned section directly with alcohol lamp, the off section vaporization. Then move the thermometer to the top of the flame and roast the vacuole with the light so that the liquid column rises slowly and leaves the flame immediately after reaching the highest mark
