thermal barrier

• 用于保护表面免受高温影响的材料或涂层，常用于航空航天、汽车和工业领域以减少热量传递。

A material or coating used to protect surfaces from high temperatures, commonly applied in aerospace, automotive, and industrial contexts to reduce heat transfer.

1. Heat insulation layerC1formal

   A material or structure designed to prevent the transfer of heat, protecting against high temperatures.

   隔热层

   • The spacecraft's thermal barrier protects it during re-entry into the atmosphere.
   • Engineers installed a thermal barrier in the engine to improve efficiency.
   • The building's thermal barrier reduces energy loss in winter.

2. Temperature limit in physicsC2formal

   A theoretical or practical limit beyond which heat transfer becomes critical or damaging.

   热障

   • The thermal barrier of the material was tested under extreme conditions.
   • Exceeding the thermal barrier can cause structural failure.
   • Researchers are developing new composites to overcome the thermal barrier.
