中文摘要：

以铜唑防腐剂（CuAz）对沙柳沙障进行处理,比较CuAz防腐剂不同处理浓度对沙柳沙障抗折强度损失率和质量损失率的变化。结果表明：不同浓度处理的沙柳沙障抗折强度损失率存在显著差异,抗折强度损失率随浓度的变化规律为3.5%〈3.0%〈2.5%〈2.0%〈1.5%

英文摘要：

A kind of waterborne preservative Copper Triazole（CuAz） was used to treat Salix psammophila checkerboard,and the influence of different concentration on the loss rate of flexural strength and mass loss rate of Salix psammophila checkerboard was analyzed.The result showed that the loss rate of flexural strength of Salix psammophila checkerboard treated with different concentration had significant difference,the change of the loss rate of flexural strength with concentration treatment was 3.5%3.0%2.5%2.0%1.5%CK.The mass loss rate of Salix psammophila checkerboard with different concentration treatment had significant difference,the change of the mass loss rate with concentration treatment was 3.5%3.0%2.5%2.0%1.5%CK.
