判别分析在铅接触者健康监护结果判定中的应用[论著]

The application of distinguishing analysis to the supervision work on lead - exposed people

目的 探讨判别分析在铅接触者健康监护结果判定中的应用价值。方法 对某蓄电池制造业近年的监测、体检资料进行判别分析。结果 建立函数式为F1=0.204 Zi+3.210 Pi+14.855 Ci—1.892和F2=0.829 Zi+14.767 Pi+23.681Ci—11.329。并用该函数式对所建模型资料和另一组资料进行判别分类,判别吻合率分别为97％和96％,经检验模型判定与实际结果均有非常显著的相关(P<0.001)。结论 用所建模型对该地区铅接触者健康监护结果来判定分类是可行的,且具有广阔的应用前景。

[Objective]To study the application of distinguishing analysis to the supervision work on lead - exposed people. [Methods] Distinguishing analysis was carried out on the supervision work and physical examination data in recent years in rechargeable battery producing manufacturing. [Results]The established functions were: F1 = 0.204 Zi + 14.855 Ci - 1.892 and F2 = 0.829 Zi + 14.767 Pi + 23.681 Ci - 11.329. Those functions were used in distinguishing and classifying the formed data and another data. The distinguishing coincidence was 97% and 96%. Significant relativity was found between the tested models and the actual result ( P < 0.01). [Conclusion]It is feasible to use formed models to distinguish and classify health supervision on the lead - exposed people, and it has a favorable prospect.
