Hexi Reservoir Project, applying filter design, is introduced, which is made up of clay central core and sandy gravel dam according to the gradation curve of clay and gravel. 介绍了合溪水库工程的概况，选用坝型为粘土心墙砂砾石坝，根据粘土和砂砾石料场的颗分曲线，对反滤料进行了设计。 - 2
Then, characteristic curve was plotted. Results (1) Overall characteristic curve of CR system was affected by gradation processing. - 3
First, a working curve must be made according to the colour gradation data and then the density of the substances is found out with the help of the extinction value of the water samples on it. 依据色阶数据制成工作曲线，再依水样的吸光值从工作曲线找出对应的物质浓度。
