摘　　要：将转动带电的Rasheed-Larsen双荷黑洞解推广到?-变形的Kaluza-Klein超引力理论中,得到了新的?-变形的转动双荷黑洞精确解,并对其热力学性质进行了仔细地分析,发现除了在电磁规范势1-形式、电荷、磁荷、静电势和静磁势中需要同时作一个电磁对偶转动以外,?-变形参数对黑洞度规、质量、角动量、热力学第一定律和Smarr公式没有影响.Generalizing the Rasheed-Larsen＇s rotating dyonic black hole solution to the four-dimensional ω-deformed KK supergravity theory,we have constructed a new solution of the rotating dyonic black hole to this ω-deformed theory and investigated its thermodynamic properties. It is considers that,besides a duality rotation needs doing simultaneously between the electromagnetic gauge potential 1-form and its dual,between electric and magnetic charges,and between electric-static and magnetic-static potentials,the ω-deformation parameter has no effect on the metric,the ADM mass,the angular momentum,the first law of black hole thermodynamics,and the Smarr formula.
