演示椭圆的曲率圆的动画。该程序演示了椭圆各点的曲率变化及相应的曲率圆圆心的轨迹。(Demonstration of the curvature ellipse circle animation. The program demonstrates the various points of the curvature of the ellipse and the corresponding changes in the curvature of the round locus of the center.)

模糊综合评判方法即将评价目标看成是由多种因素组成的模糊集合（称为因素集u），再设定这些因素所能选取的评审等级，组成评语的模糊集合（称为评判集v），分别求出各单一因素对各个评审等级的归属程度（称为模糊矩阵），然后根据各个因素在评价目标中的权重分配，通过计算（称为模糊矩阵合成），求出评价的定量解值。它是应用模糊变换原理和最大隶属度原则，对各因素作综合评价的。(The fuzzy comprehensive evaluation method is about evaluation goal as a fuzzy set by a variety of factors (called factor set u) set the assessment level of these factors can be selected to form the fuzzy set of reviews (called evaluation set v) were calculated the level of the individual assessment of each single factor attribution the quantitative solution value (called a fuzzy matrix), then the weight distribution according to various factors in the evaluation objectives, by calculating (called fuzzy matrix synthesis), obtained evaluation . It is the application of fuzzy transform principle and the principle of maximum degree of membership for a comprehensive evaluation of various factors.)
