温度计在食用菌生产中必不可少。在使用过程中,由于不慎致使温度计液柱断节的事时有发生。温度计液柱的断节如何处理呢?据作者试验,以下方法行之有效:①用一根绳系住温度计的上端,手拿绳的另一端作高速圆周旋转,在离心力的作用下,便可使断节回原。②将温度计的液泡放在火源上烘烤,注意不要让液泡胀破。在热力的作用下,液柱上升,待和断节的部分连在一起时,即成。
Thermometers are essential in mushroom production. In the process of using, due to inadvertently caused the thermometer liquid column broken things happen. According to the author’s test, the following methods work well: ① use a rope to fasten the upper end of the thermometer, the other end of the hand rope for high-speed circular rotation, under the action of centrifugal force, you can So broken section back to the original. ② the thermometer on the source of the fire on the baking bubble, be careful not to let the bubble burst. Under the action of heat, the liquid column rises until it is connected with the broken section.
