摘　　要：以Gibbons-Maeda dilaton黑洞和Garfinkle-Horowitz-Strominger dilaton黑洞为例,研究空间的非对易性对黑洞热力学性质的影响.通过对比对易时空中Gibbons-Maeda dilaton黑洞和非对易时空中Garfinkle-Horowitz-Strominger dilaton黑洞的温度,得出如下结论:从对黑洞热力学性质产生影响这一角度来说,时空的非对易性和黑洞的荷(电荷或磁荷)有相似的作用.　Considering a Gibbons-Maeda dilaton black hole and a Garfinkle-Horowitz-Strominger dilaton black hole,the effect of space noncommutativity on black hole thermodynamics is investigated.By comparing the Gibbons-Maeda dilaton black hole in commutative space with the Garfinkle-Horowitz-Strominger dilaton black hole in noncommutative space,it has been concluded that the noncommutativity of the space has an effect on Garfinkle-Horowitz-Strominger dilaton black hole similar as has the electric or magnetic charge in Gibbons-Maeda dilaton black hole.
