人教版初中物理第一册中P143,关于阿基米德原理的实验,采用倾斜放置的烧杯作为溢水杯,不足之处是物体放入烧杯后,有部分水沿烧杯的外壁流走而不流入小桶内,因而有较大的误差,笔者对溢水杯作了如下改进。虹吸管的一端插入烧杯中(如图1-(a)所示),在烧杯中...
In the first edition of PEP Junior Physics physics, P143, on the experiment of Archimedes’ principle, a tilted beaker is used as an overflow cup. The disadvantage is that after the object is put into the beaker, some water flows along the outer wall of the beaker without Into the keg, so there is a larger error, the author made the following improvements to the overflow cup.
