Multi - strategy means as follows : utilizing classifying data mining methods based on decision tree to analyze the data in grade database . a grade decision tree is generated to show directly a position of grade according to different computing methods and to support estimate . at the same time , utilizing classification method based on summing - up principles to do such things as grade query analysis and prediction and contrast analysis to realise automatic generation of grade analysis report , test paper ’ s quality assessment report and quality analysis table which plays an active role in improving teaching and test paper ’ s quality 这里多策略主要是指:采用基于决策树的分类挖掘方法,对学生成绩库中数据进行分析,生成学生成绩决策树,能直观显示出某一成绩在不同等级计算方式中所处的位置,为教学部门提供评价信息;同时采用基于总结规则的统计分析方法,完成不同情况下的成绩查询、预测及对比分析,实现学生成绩分析报告、试卷质量评价报告及质量分析表的自动生成。
The distributed remote temperature measurement and supervision system is made up of four main parts : 1 . central computer the software in central computer supervise and control the whole temperature measuring system . the data of temperature are collected , processed , recorded by the central computer 在上位机运行的测温管理软件，负责对整个系统进行统一管理，实现对系统参数的设置，对多个测温点温度数据的巡回采集、处理、实时直观显示和对温度报表的查询、打印。
