在反de Sitter空间中，我们研究了维度连续引力中荷电黑洞的热相变。我们发现偶数维视界为球面的黑洞在温度-熵平面上存在类van der Waals相变，而具有平坦和双曲几何形状的黑洞不存在这种相变。在临界拐点附近，计算了临界指数，其值不依赖于尺寸。在一级相变的温度-熵图中，验证了麦克斯韦等面积定律的成立。在奇数维中，任何视界几何形状的黑洞都不存在热相变。
We study the thermal phase transitions of charged black holes in dimensionally continued gravity in anti-de Sitter space. We find the van der Waals-like phase transition in the temperature-entropy plane of the black holes with spherical horizons in even dimensions, and there is no such phase transition of the black holes with flat and hyperbolic geometries. Near the critical inflection point, the critical exponent is computed and its value does not depend on the dimension. The Maxwell equal area law is checked to be fulfilled in the temperature-entropy diagram for the first order phase transition. In odd dimensions, there are no thermal phase transitions for the black hole with any geometry of the horizon.
