覆面材料 meaning in Chinese

facing material

Based on the date of full - scale measurements , modeling wind tunnel tests and theoretical researches of the wind loads on low - rise buildings available , involved the date of the wind tunnel test and computational numerical simulation fulfilled in this paper , the effects of wind loads on low - rise buildings have been studied systematicaly and extensively . it reveled properly the principle of the changes of the surface mean pressures , local pressures , and fluctuating pressures with the building geometry , roof type and slope , wind direction , eave configuration , cladding system , and dominate openings
本文根据国内外有关低层房屋风荷载的全尺寸实测、模型风洞试验及其理论方面的研究，包括本文进行的低层房屋屋面风压分布的风洞模型试验和计算机数值模拟计算，对低层房屋的风荷载特性进行了系统而深入的研究，较好地揭示了低层房屋表面的平均风压、局部风压和压力的波动随房屋的几何尺寸、屋面形式、屋面坡度、风向角、檐口构造、覆面材料和门窗开洞而变化的特点和规律。
