摘　　要：在被动技术日益受到重视的今天,作为传统岭南建筑墙体构造之一的蚝壳墙因为其优良的隔热性能,重新引起了人们的关注。为了得到蚝壳墙的相关热工参数,利用双面热流计法,对沙湾镇的一座蚝壳墙建筑进行了现场测试。实验结果表明,蚝壳墙传热系数较小,且温度和热流的衰减与延迟作用非常明显。As passive technique is more and more serious nowadays, the oyster-sheU wall, which is one of the architectural wall structures for the traditional buildings in the south of Five Ridges in China, causes people＇s attentions again for its excellent heat insulation performance. Two-sided heat flow meter method is used to test a building made of the oyster-shell walls in Shawan Town on-site, in order to ob- tain the oyster-shell wall＇s heat parameters. The test results show that the oyster-shell wall＇s heat transfer coefficient is small, and its decay and delay effects in temperature and heat flux are very considerable.
