摘　　要：将ηξ时空理论与适当的复时间变换有机结合,构造了所谓ηξ复时变换,它给出ηξ时空中的截面转动,从而诱导出虚时、实时热场理论间的直接变换,这从背景时空的角度揭示了虚时。Some suitable complex\|time transformation is combined organically with the theory of η\|ξ spacetime and a so\|called η\|ξ complex\|time transformation is constructed.This gives some section rotations in η\|ξ spacetime and induces a direct transformation between the imaginary\| and real\|time thermo field theories.These reveal some internal relations between the imaginary\| and real\|time thermo field theories based on the view\|point of background spacetime.

关 键 词：η-ξ时空 戴面转动 热场理论 虚时 实时
