| Abstract: | The appliance reasons that can result in the system error when measuring water samples using catalysis-digestion-sealed method were illustrated in this paper.Deficient precision in the production of oxidation ditches can bring about the system error.Also the range of error and the methods for system error reduction were discussed. |
