图5 古里雅冰帽和冰水沉积物不同粒度样品平均曲线的正态分布拟合 注：黑色实线为样品测量的粒度曲线，绿色实线为拟合的粒度曲线，不同颜色的虚线为分解出的粒度分量，并给出了各分量的众数粒径、含量和每个样本的拟合残差

Fig.5 Normal distribution fitting of average grain-size curves of different sediment samples from the Guliya glacial region Note：The black solid line is the particle size curve measured by the sample，and the green solid line is the fitted particle size curve. The dotted lines in different colors are the decomposed particle size components，and the mode particle size and content of each component and the fitting residual of each sample are given
