| 摘 要： | 一、导论 如所周知,作为公用的测量单位制,在热工学范畴内,SI制采用米（m）、秒（s）、公斤kg]及温度（K）作为基本单位,相应的基本量纲为L]、(T]、M]和θ]。而工程制则采用米（m）、秒（s）、公斤力kgf]、温度（K）及大卡（Kcal）作为基本单位,相应的基本量纲为L]、T]、(F]、θ]及Q]。工程制比SI制多用了一个基本单位Kcal和基本量纲Q]。作为公用单位制它们都是科学的,但SI制更简化些,因

| Abstract: | In this method of dimensional analysis the problem with that the dimension heat Q] whether ought to be introduced as a independent one is only depended on that the transform between heat and mechanical energy whether take place in the phenomenon which is investigated, and is not depended on which system of units is used. This is explanded by physics, Some examples are given to explan this viewpoint in more detial. |
