This paper briefly introduces the homogeneous theorem and the Π theorem in dimensional analysis，
and then specifically cites the teaching application of dimensional analysis in the thermodynamics part of college
physics. Our solution process is：analyzing and listing the possible physical quantities;writing a dimension table of
all physical quantities;analyzing the dimension table，determining the relevant physical quantities and independent
dimension;setting the dimensionless quantity equation;listing and solving the dimension index equations.
