Abstract: In order to ascertain transformation relation about temperature and quantity of heat in relativistic thermodynamics,the peculiarity of time-like leading-force is analyzed,and Ott thermodynamic cycle is applied to cylindrosymmetric relativistic system on rotating disk with homogeneous angular velocity.When angular velocity of rotating disk is constant,time-like leading-force leads to the local contraction of motion-quantity of heat and motion-temperature,the ratio of contraction is associated with cylindrical radius of subsystem,and leads to the global contraction of motion-quantity of heat,its ratio is associated with cylindrical radius of outer margin of system.Deduced from the same Ott model in this paper,the obtained conclusion is exactly consistent with theory of Planck-Einstein school.Finally,the local distribution law on proper temperature of rotating system in thermal equilibrium is deduced,and the experimental mechanism which directly detects theories of P-E school and O-M school in relativistic thermodynamics is put forward.
