取一支50mL的注射器，用凡上林涂擦注射器的活塞，拉动活塞使注射器里吸进少许乙醚，取下针头，迅速用橡皮帽堵住注射器的小孔。用热水给注射器加温，乙醚迅速汽化，同时用手向外拉活塞，使液态乙醚全部消失，完成汽化实验。用手推活塞，压缩乙醚蒸气，很快出现液态乙醚，完成
Take a 50mL syringe and wipe the plunger of the syringe with Shanglin. Pull the plunger to suck a little ether into the syringe. Take off the needle and quickly close the hole of the syringe with a rubber cap. The syringe was warmed with hot water, and ether was quickly vaporized. At the same time, the piston was pulled outwards by hand so that the liquid ether disappeared completely and the vaporization experiment was completed. Push the piston by hand, compress the ether vapor, and liquid ether will appear soon.
