摘要:
为了提高实验室检测结果的准确性和可比性，采用四分位稳健统计和主成分分析法对临沂市9家复混肥企业实验室常检项目氮、磷、钾和氯离子的结果进行分析。结果表明：各实验室对氮和磷的检测结果均为满意；对钾测定结果除1家不满意外，其它均为满意；对氯离子测定结果有6家满意，1家结果有疑问，2家结果不满意。各实验室综合检测能力强弱排序为：L7＞L2＞L8＞L3＞L1＞L6＞L5＞L4＞L9。
Abstract:
In order to enhance the accuracy,reliability and comparability of the laboratory testing results,using the quartile robust statistical and principal component,the nitrogen,phosphorus,potassium and chloride ion in compound fertilizer were analyzed in Linyi.The results showed that the testing results of nitrogen and phosphorus were satisfied by each laboratory; all the fertilizer companies were satisfied with the results except one company was not satisfied with the measurement results of potassium; The chloride ions were satisfying by six companies,the results were doubtful in one company,and two companies did not meet the request. Results also showed that the detection ability exhibited different in the order was L7＞L2＞L8＞L3＞L1＞L6＞L5＞L4＞L9.
