The dual-cured resin cements are polymerized with the chemical curing and the light activation. However, it is pointed out that the amount of light through an adherent material is important for its polymerization. The purpose of this study was to investigate the influence of irradiation conditions on the physical properties of dual-cured resin cements.First of all, the marketed activator lights were evaluated. Their light intensity and distribution of wave length were many variances. The physical properties were influenced by trradiation conditions. The improvement of their physical properties was most likely due to increased light activating. The light energy (light intensity x irradiation time) was one of the most important factors for increasing physical properties. When the amount of light was the same. no differences were observed of these cements. The light activating intensity and sequence were very important factors influencing dentin bond strenghths.And the pre-mix activation of the liquid as a new method. The setting time of the cement mix with pre-mix activation was shorter than with no activation. The compressive strength and flexural strength incresed with the pre-mix and post-mix activation.As the conclusion, the performance of this product is highly dependent upon proper light curing tehnique. This demands the operator's close attention to the cure times, light access to the materials, distance of the light from the materials, and light intensity.

双固化树脂水门汀是通过化学固化和光活化聚合而成。然而，指出通过粘附材料的光的量对于其聚合是重要的。本研究的目的是探讨辐照条件对双固化树脂水门汀物理性能的影响。它们的光强度和波长分布是多种多样的。辐照条件对材料的物理性能有影响。其物理性质的改善最有可能是由于增加了光活化。光能（光强×辐照时间）是提高物理性能的最重要因素之一。当光量相同时。没有观察到这些粘固剂的差异。光活化强度和光活化顺序是影响牙本质粘结强度的重要因素，而预混液光活化是一种新的方法。有预混合活化的水泥混合物的凝固时间比没有活化的短。抗压强度和抗折强度随预混和后混活化的增加而增加，说明该产品的性能在很大程度上取决于合适的光固化工艺。这就要求操作人员密切关注固化时间、光对材料的影响、光与材料的距离以及光强度。
