In this paper, the overcharging problem and thermodynamics in the extended phase spaces of the five-dimensional spherically symmetric topological black holes are investigated by absorptions of scalar particles and fermions. The cosmological constant is regarded as a variable related to pressure and its conjugate quantity is a thermodynamic volume. The first law of thermodynamics is recovered. The second law is violated in the extended phase space of the extremal and near-extremal black holes. The overcharging problem is tested by the existence of the event horizons. The event horizon is determined by the metric component . The minimal values of the metric component at the final stage show that the extremal and near-extremal black holes can not be overcharged.

扩展相空间中的过充电问题和热力学
通过标量粒子和费米子的吸收,研究了五维球形对称拓扑黑洞扩展相空间中的过充电问题和热力学。宇宙常数被视为与压力有关的变量,其共轭量为热力学体积。恢复了热力学的第一定律。在极黑洞和近极黑洞的扩展相空间中违反了第二定律。通过事件范围的存在来测试过度充电问题。事件范围由指标组件确定。在最后阶段,度量成分的最小值表明,极端和接近极端的黑洞不会被过度充电。
