用比较法将标准水银温度计与被检温度计同置于恒温槽中,待示值稳定后,按标准——被检——被检——标准的次序读取温度计示值(这样读数作为一个往返),每支温度计往返5次共读取10次,五次读数完成后将标准器旋转180°进行另一面5次读数,分别求得标准和被检的示值平均值,然后通过公 Compare the standard mercury thermometer with the seized thermometer in a thermostatic chamber with a comparative method and read the thermometer indication in the order of standard-seized-seized-standard after the indication has stabilized (such reading as a round trip ), Each thermometer round trip 5 times to read a total of 10 times, five readings after completion of the standard 180 ° rotation of the other side of the five readings were obtained standard and seized average value, and then through the public
