摘要	It has been suggested that the standardised growth curve (SGC) method can be used to determinate D(e) accurately and reduce the measurement time. However, different opinions regarding the applicability of the SGC method exist. In this paper, we report the construction of quartz OSL SGC for 35 aeolian samples from different parts of the Horqin dunefield in northeastern China, and then test their applicability for D(e) determination. Our results suggest that: 1) up to a regeneration dose of 80 Gy, the SGC of the Horqin dunefield can be fitted using the exponential plus linear equation, with the r(2) value of 0.97, and all the regeneration dose points closely stick to the fitting line, implying that all samples share a very similar dose-response curve; 2) for samples with D(e)s ranging from 1 to 50 Gy, the ratios of SAR D(e) to SGC D(e) fall within the range of 0.9-1.1, and the average ratio of SAR D(e) to SGC D(e) is 1.01 +/- 0.01, close to unity. Therefore, the construction of SGC is correct, and the SGC is an effective procedure for accurate D(e) determination for samples from the study area.
