| Abstract: | The first law of thermodynamics is very important part of thermodynamics, engineering thermodynamics and college chemistry. Described selecting method of two sets of symbols and explained four kinds of expression about this law in detail. Students' understanding of the first law of thermodynamics has been enhanced greatly through teaching practice, and achieved the very good teaching results. |
