- Abstract:
- This article mainly uses different statistical methods based on different probability distribution. It has studied the background value of CU, PH, PH, Mi, CR, CR, and CD in the dry stream sediment in the Yellow River. In order to ensure the reliability of its methods and data, the measured data statistical methods are tested, and the background values of the Yellow River in the background values of the flow of mud are the same as the domestic and foreign soil soil. The vegetarian background value is compared, and the value is basically within the scope of its list; the value of the factor sequence is used to find the right value and evaluate the current situation of the sediment.
