一、简易气压式温度计的制作 用一薄壁细小瓶子,往该瓶注入大半瓶的红墨水,然后用一个中间插有细小的、长的、空心玻璃管的塞子塞紧瓶口,不能漏气,玻璃管需插到瓶底。 此温度计的工作原理是:未装满红墨水的瓶有空气,当空气受热或冷却时,相应地发生膨 First, the production of a simple pneumatic thermometer uses a thin-walled, thin bottle, injects a large part of the bottle of red ink into the bottle, and then uses a stopper with a small, long, hollow glass tube inserted in it to tightly seal the bottle mouth. The glass tube needs to be inserted into the bottom of the bottle. The working principle of this thermometer is: the bottle that is not filled with red ink has air, and when the air is heated or cooled, the corresponding swelling occurs.
