For the evaluation of the algal soiling of wood-based materials, a new accelerated test method under outdoor conditions was designed and applied to the different types of sample boards. The test method consisted of exposure with 45 degree inclination facing to the north and mist-spray of water including ammonium phosphate as a nutrient. The species of the algae and their development on the specimens detected within 3 to 5 months were closely correlated with those observed by surveys on the external surfaces of buildings on the current situation. The newly designed test method was assumed to be suit for estimation of the algal growth on external materials within a short period representing the natural soiling.The cultivation method consisting of spraying the algal cells and the nutritional solutions, as well as in a room conditioned at high humidity and sunshine was assumed to be an effective technique to estimate the degree of algal soiling in a laboratory experiment.When the accelated test method was conducted to the different types of external materials, a rapid development of algal soiling was detected on the ssmples which easily absorbed water from these surfaces.

为评价木质材料的藻污性，设计了一种新的室外加速试验方法，并应用于不同类型的样板。试验方法包括以45度倾角朝北暴露，并喷洒含有磷酸铵作为营养物质的水。在3 ~ 5个月内检测到的标本上的藻类种类和它们的发展与现状下建筑物外表面的调查结果密切相关。新设计的测试方法被认为适合于在短时间内估计藻类在代表自然土壤的外部材料上的生长。培养方法包括喷洒藻类细胞和营养溶液，以及在高湿度和阳光条件下的房间中，被认为是在实验室实验中估计藻类污染程度的有效技术。方法进行了不同类型的外部材料，藻类土壤的快速发展，检测到的样品上，容易从这些表面吸收水。
