摘　　要：阐明了用密封催化消解法测量水样时可能带来系统误差的器械原因:当消解管生产加工的精度不高时会带来系统误差.分析了可能产生的误差大小,探讨了降低误差的方法.The appliance reasons that can result in the system error when measuring water samples using oatalysis-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.
