摘　　要：对文献[1]提出的零温到有限温度时空的普遍坐标变换作了推广讨论.用共形异常和Green函数的方法计算了温度时空的能量密度和基态能,证明坐标变换的虚时频率就是温度时空的Hawking辐射温度.并运用热力学第零定律等价于钟速同步的传递性的论断讨论了上述结论.The conclusion in the reference [1 ] is extended and more general coordinate transformation from zero-temperature space-time to nonzero-temperature one is presented. By using the method of conformal anomaly and Green function, the ground state energy of new space-time has been calculated separately, and been proved the relationship between the imaginary time frequency of the coordinate transformation and the radiation temperature. With the zero-th law of thermodynamics equivalent to the transitivity of clock rate synchronization, the above-mentioned conclusion can also be obtained.
