我们通常用排水法测量不规则物体的体积,即先在量杯或量筒中放入一定量的水,记住水的体积,然后把不规则固体放入水中,再读出水面上升后水的体积,两者的差就是固体的体积。如果测量体积比较小的固体,用这种方法测出的结果误差较大,而且遇到比水的密度小的固体,还要把固体压入水中才能测量,很不方便。下面,大家快来试试我发明的微小固体体积测量仪吧,它能很好地解决上述问题。
We usually use the drainage method to measure the volume of irregular objects, that is, first in the measuring cup or measuring cylinder into a certain amount of water, remember the volume of water, and then the irregular solid into the water, then read out the water volume The difference between the two is the volume of the solid. If you measure a smaller volume of solids, the results of this method measure the error, and encounter a smaller density than water solids, but also the solid pressure into the water to measure, very inconvenient. Next, we come to try my invention of a small solid volume measuring instrument it, it can be a good solution to the above problems.
