那种钉子可以用pin来表达，既可当名词，也可作动词玻璃棒stirring rodwiki的解释A stirring rod is a piece of laboratory equipment used to mix chemicals and liquids for laboratory purposesanswers网站的解释A stirring rod is a glass rod, typically about 6 inches to 1 foot long and 1/8 to 1/4 inch in diameter that can be used to stir liquids in flasks or beakers. You can also use a stirring rod to help pour liquids without spilling. Because of surface tension, liquids tend to run down an object. So if you hold a glass rod vertically, with one end in the opening of the beaker or flask you are pouring into, and then hold the top end of the glass rod against the rim beaker you are pouring out of, the liquid will run down the rod and not spill. Be careful... it might take a little practice to get the proper technique! 其中出现了beaker and flask，即烧杯和烧瓶，也是实验室常见器皿。
