现在常见的温度计由一个玻璃管和一个位于底部的贮液槽组成，贮液槽中的水银或酒精沿玻璃管上升形成液柱。

A thermometer often now, and more often back in the early 1800s, consists of a glass tube up which a column of mercury or alcohol can travel from a reservoir at the base.

停止泵压，关闭柱的出口，去除填压用的贮液器。首先从试管架上卸下柱体，然后从槽上拧下贮液器，这样就很容易完成。

Stop the pump, close the column outlet and remove the packing reservoir. This is most easily done by first removing the column from the stand and then unscrewing the reservoir over a sink.
