Knoop hardness measurements of UV-polymerized dental composites showed that, at a certain depth below the surface, the degree of cure rapidly decreases. The depth of cure was found to be critically dependent on the UV source and exposure time used. A theoretical model was derived which was in quantitative accord with the results.
对紫外线聚合牙科复合材料进行努氏硬度测量表明，在表面以下某一深度处，固化程度会迅速降低。结果发现，固化深度严重依赖于所使用的紫外线光源和照射时间。由此推导出一个理论模型，该模型与实验结果在数量上相符。
