在准备验证气态方程实验时,须把水银灌入一端封闭的U形管内,我们试用了好几种方法,经多次的试验,不断地改进,现在找到了一种灌水银的快速法。一、准备过程 1.先削一两根约为火柴杆一半粗细、长约25厘米的竹签(因为U形管总长度约21厘米),一端削成扁尖形,长约8厘米(如图1所示)。 In preparing the experiment for verifying the gas equation, mercury was poured into a closed U-tube at one end. We tried several methods and, after repeated tests, continued to improve. We have now found a rapid method of filling silver. First, the preparation process 1. First cut one or two about half the thickness of the matchstick, about 25 cm bamboo stick (because of the U-shaped tube total length of about 21 cm), one end cut flat tip shaped, about 8 cm Figure 1).
