我们给出了在3维和4维规范群为SU（2）和Z2的纯格点规范理论中涡旋自由能和弦张力的g− 24阶高温展开结果。对于四维SU（2），所得结果与Creutz的Monte Carlo计算结果进行了比较，两者符合得很好。一个中间耦合区域，弦张力平滑地插入强耦合和弱耦合行为之间。
We present results of high temperature expansions up to order g−24for the vortex free energy respectively string tension in pure lattice gauge theories with gauge groups SU(2) and Z2in 3 and 4 dimensions. For SU(2) in 4 dimensions the result is compared with Monte Carlo calculations of Creutz and is in good agreement. An intermediate coupling region is seen, where the string tension smoothly interpolates between strong coupling and weak coupling behaviour.
