摘　　要：Any description of gluons requires a well-defined gauge.This is complicated non-perturbatively by Gribov copies.A possible method-independent gauge definition to resolve this problem is presented and afterwards used to study the properties of gluons at any temperature.It is found that only chromo-electric properties reflect the phase transition.From these the gauge-invariant phase transition temperature is determined for SU（2） and SU（3） Yang-Mills theory independently.Any description of gluons requires a well-defined gauge.This is complicated non-perturbatively by Gribov copies.A possible method-independent gauge definition to resolve this problem is presented and afterwards used to study the properties of gluons at any temperature.It is found that only chromo-electric properties reflect the phase transition.From these the gauge-invariant phase transition temperature is determined for SU（2） and SU（3） Yang-Mills theory independently.
