摘　　要：成绩评价是学生学习活动过程中一项重要的工作,评价方法要求客观、全面和公正。以中介数学系统为背景,为处理工程实践和科学研究中普遍存在的模糊现象提供一种度量逻辑真值程度的方法,即引入中介真值程度的度量方法来研究成绩评价方法。在确定所给的考试分数区域与其对应谓词的真值之间的关系后,根据真值程度函数进行了算法设计,给出了成绩的单项和综合评价。通过实例分析可以看出,该算法设计能全面、定性地反映个体成绩的优劣,方法更科学、公正和全面。鉴于评价系统的相似性,文中所涉及的中介真值程度的度量算法在评价、决策与管理科学中会得到广泛应用。The grade evaluation is an important task within the student studying procedure.That means the evaluating method would demand impersonality,completeness and justice.To process fuzzy phenomenon existed widely in engineering and scientific research,a new method with measuring logic truth scale,which has background of medium mathematics system,is provided.Introduce a new measuring method-the measure of medium truth scale with measuring logic truth scale that is used in processing grade evaluation.After defining of the relation between truths of the predicate and areas of numerical value,the algorithm is designed based on the truth scale and then the single and general evaluation of the grade is made.Through the comparison analysis with the example,the conclusion is come to that this algorithm designed here makes more scientific and comprehensive general evaluation by using logical truth that not only reflects the quality of the individual grade in an all-round and qualitative way but also sorts order of the individuals in the sample space in a quantificational way.Considering the similarities in the evaluating system,the algorithm of the measure of medium truth scale will be widely used in fields such as evaluation,decisionmaking and the science of management.
