摘　　要：评价是科学研究和社会现实中科学地做出管理决策的依据。文中将处理模糊现象的中介数学系统引入到评价方法中,以中介真值程度度量为基础,提出采用距离比例函数实现单项的评价,采用加权距离比率和函数实现n项综合评价的新方法,并将该方法应用到虚拟现实系统沉浸感度量中。利用距离比率函数对单个感官的沉浸感进行度量,利用加权距离比率和函数对以身体多种感官感知为基础的虚拟现实系统沉浸感进行度量。研究结果表明,该评价方法易于将一些代表性的指标量化,采用该方法对事物进行评价更为客观和合理。Evaluation is the basis of making decision scientifically in management work of science research and real world. It introduces medium mathematics system which is employed to process fuzzy information for evaluation. It presents a new evaluation methods based on the measure of medium truth degree. It uses distance ratio function to make the evaluation of one-item and uses sum function of weighting distance ratio to make the comprehensive evaluation of n-items. Furthermore, this method is applied to the measuring of the im- mersion in virtual reality system which uses the distance ratio function to evaluate the immersion of single sense and uses the sum function of weighting distance ratio to evaluate the immersion of multi-senses. It shows that the new evaluation method is easy to quantize the rep- resentative index and more reasonable and objective.
