Dimensional analysis is a very important content in college physics teaching,but there are still some big deviations in the process of teaching at present. For this reason,taking the dimensional analysis method of rotational inertia of three-line pendulum as an example,this paper compares the results of general dimension solution with the revised after considering the action form of physical quantities,and expounds the contents that should be considered in the process of applying dimension solution.
Key words: dimension; dimensional analysis method; three-line pendulum
