"Thermoelectricity can produce electric energy from a difference in temperature. There has to be a temperature gap in a conductor or semi-conductor material".
温差电能从不同的温度制造电能，必须是导体或半导体物质中的温差。
Temperature difference from top to bottom in preheating zone of tunnel kiln is the biggest obstacle for rapid firing, energy saving.
隧道窑预热带内上下温差过大是实现快速烧成、节能降耗的最大障碍。
