这是一根铜柱。我们知道纣王和妲己发明了炮烙之刑，这根铜柱就是施刑的工具。将铜柱置于炭火之上，令受刑的人在铜柱上行走，受刑之人受不了烫就掉在炭火之中被活活烧死。

This is a copper beam. We know that King Zhou and Daji invented torture by walking on a heated copper beam. This copper beam was an instrument in torture. The beam was placed upon a bed of hot coals, and someone being tortured would walk on the beam. The person being tortured would be unable to withstand the heat and would fall into the hot coals and burn to death.
