【Abstract】 C”is an extremely important unit in the theories of heat, it is showed that in the classical statistics theories, though “C” can be deduced and explained microcosmically,the deductions and explanations are not completely tally with experiment results, that is, there are certain flaws with them, then, when it develops into the quantum statistics, “C”can be perfectly deduced and explained.That reflects the facts that theories of heat are the law and feature of physics development, and that the establishment and development of quantum mechanics is inevitable.
