扶手盖：采用实木材质制作成型，多层油漆工艺。
Armrest cover: solid wood material production molding, multi-layered paint process.
其步骤包括：从生产商了解热熔膜的结构是单层相同材质还是多层不同材质。
The procedures are: learning about from the producer whether the structure of the thermo melt membrane is of single layer or multi layers.
若是多层不同材质，先对样品的上下表面进行全反射红外光谱测试，确定上下表层成分。
If the structure is of multi layers, first the upper and the lower surface of the sample go through fully reflective infrared ray test; the components of the upper and lower surface are determined.
