导体：任何允许电流和热能流动的物质。
Conductor: Any of various substances that allow the flow of electric current or thermal energy.
结果表明，随着辐射热能流率的增加，着火时间缩短，着火温度降低；
The ignition temperature and ignition delay time decreased with the increasing radiant heat flux.
电导体一般是用金属制成的。热导体能使热能流动，因为它无法吸收辐射热；这类物质包括了金属和玻璃。
Electrical conductors are usually metallic. Thermal conductors allow thermal energy to flow because they do not absorb radiant heat; they include materials such as metal and glass.
