B 肾炎的诊断2.doc

肾炎的诊断人们到医院就诊时，通常要化验一些指标来协助医生的诊断。诊断就诊人员是否患肾炎时通常要化验人体内各种元素含量。表B.1是确诊病例的化验结果，其中130号病例是已经确诊为肾炎病人的化验结果；3160号病例是已经确诊为健康人的结果。表B.2是就诊人员的化验结果。我们的问题是：1. 根据表B.1中的数据，提出一种或多种简便的判别方法，判别属于患者或健康人的方法，并检验你提出方法的正确性。2. 按照1提出的方法，判断表B.2中的30名就诊人员的化验结果进行判别，判定他（她）们是肾炎病人还是健康人。3. 能否根据表B.1的数据特征，确定哪些指标是影响人们患肾炎的关键或主要因素，以便减少化验的指标。4. 根据3的结果，重复2的工作。5. 对2和4的结果作进一步的分析。表B.1 确诊病例的化验结果病例号CuFeCa115.824.5700215.731.570139.8025.9541414.239.7896516.223.860669.299.29307713.326.6551814.530.065998.857.865511011.532.56391115.917.75781211.311.3767139.2637.1958148.2327.1625156.6321.06271610.711.76121716.17.049881810.14.0414371920.723.812322010.39.706292112.453.13702213.853.36212312.217.91139243.3616.8135255.8424.98072615.847.36262711.66.306082814.69.70421293.278.176223028.832.49923119.136.222203213.929.812853313.219.815213413.090.815443513.114.122783612.918.629933715.027.020563814.437.010253922.831.01633401353226747418.0030810684217.38.652554438.1062.81233446.4386.92157456.4961.738704615.623.418064719.117.024974819.764.220314965.435.053615024.486.036035120.115531725225.028.223435322.235.52212548.9936.016245518.617.737855617.324.830735724.017.038365821.593.221125916.138.021356021.035.01560表B.2 就诊人员的化验结果病例号CuFeCa615.4229.7323621.8740.5542630.8012.51332641.703.99503650.7015.1547661.094.2790670.309.11417684.169.32943690.5727.3318707.0632.91969718.2822.61208725.8734.8328732.8415.72657419.136.222207520.123.816067610.530.56727713.219.815217813.090.815447920.128.910628013.114.122788112.918.629938215.027.020568314.437.010258422.831.31633858.
