surface heat flow meaning in Chinese

地面热流

The thermal storage and heat transfer of pcm wallboards were studied , the ‘ decrement factor ’ and ‘ time lag , which are used to evaluate the material with constant thermo physical properties , can ’ t be used to evaluate the pcm wallboards , because the melting or freezing of pcm can charge or discharge high latent heat during a narrow temperature range , which causes different temperature distribution in the walls and different surface heat flow into the indoor environment
探讨了墙体相变建筑构件的蓄热、传热特性。与常物性建筑构件对室外温度波动衰减(用衰减系数表示)和延迟(用延迟时间表示)的特性不同,相变建筑构件在较窄的范围内有大量潜热的吸收或释放,从而显著的影响其温度分布和表面向室内的传热速率。
