含温度背景下宇宙弦的引力场

考虑温度效应，运用改写的能自发破缺产生整体宇宙弦的标量场在有限温度下的拉氏密度，求解了整体宇宙弦核外的引力场方程，对零温理论中的结果作了修正，进而讨论弦核外引力场的性质。

The Gravitational Field of a Global Cosmic String Considering Temperature Effect

Using the Lagrangian at a finite temperature of the scalar field which can generate global cosmic strings in the spontaneous breakdown. Solved the gravitational field equation outside the core of a global cosmic string at the background of temperature, corrected the result in the theory at zero temperature. On the basis of this, the properties of the gravitational field outside the core of a global cosmic string are discussed.
