With wall paint and wood, for example, the drop of temperature will cause a sharp contraction in lacquer and wood interface, resulting in a variety of cracking phenomenon.
以墙漆和木器为例，气温急降会造成漆面和木器接口急剧收缩，引致各种开裂现象。
Coating and the substrate surface temperature of the coating would have a bad contraction stress, caused by cracking and peeling off the coating.
涂层与基体表面的温度差会使涂层产生收缩应力，引起涂层开裂和剥落。
