常用温度计在运输和使用过程中会因剧烈的震动和撞击而致使温度计内的液柱断开,这种温度计不可再用来测量物体的温度,但只要将断开的液柱重新连接起来,便可恢复其功能,发挥其作用,现将此法介绍如下: (1)测高温法 此法适用于被断开的液柱非常短(1毫米左右),而且断开的距离非常近的温度计,具体做法是:将水(或其它液体)加热至断液柱温度计的最大刻度值温 Commonly used thermometers in the transport and use of the process will be due to severe vibration and impact caused the liquid column in the thermometer disconnected, this thermometer can no longer be used to measure the temperature of the object, but as long as the disconnected liquid column reconnect Can resume its function, play its role, now this method is introduced as follows: (1) pyrometry This method is applied to the liquid column is disconnected is very short (about 1 mm), and the distance is very close to the thermometer, The specific approach is: the water (or other liquid) heated to the off-column thermometer maximum scale value temperature
