The physical implication of the so called "temperature of a moving body" was investigated. On careful analyses of the transfer of energy and heat between two bodies in relative motion. the following results were obtained: Just as in traditionary thermodynamics

so either in Planck-Einstein or in Ott-Moller formulation of relativistic thermodynamics

the "temperature" of a moving body can be regarded as the "potential of heat flow under purely thermal interaction". However

for lack of agreement on the definition of the "work"

within relativistic thermodynamics

the "purely thermal interaction" can be defined differently. This has led to various opinions in temperature transformation about a higher or lower temperature for a moving body. In substance

different formulation are des cribing in different forms the very same physical reality; so

they are compatible.When one and the same formulation is followed

both the "hot-cold relationship" between moving bodies and the concept of "purely thermal interaction" depend on the selection of frame of reference. On this basis

an analysis about Landsberg’s thought experiment shows that there is not any logical contradition.
