It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

Methods: The following measurements were obtained using a slidin g gauge and ophthalmostatometry on children 5～17 years of age: The anthropometr y of interpupillary distance, inter outer canthal distance, inter oto bsion superius distance, length of nose, inter alare distance , frontal angle, distance between otobsion superius and outer canthus, and exophthalmus.

对厦门市5～17岁儿童少年2600人以电子数显游标卡尺、弯脚规和Hertel眼球突出计进行了瞳孔距离、眶距、耳根上点眶距、耳根上点间宽、眼球突出度、鼻高、鼻宽和鼻基根角的活体测量。

During open/close movement, the distance of condylar movement is smaller than normal occlusion(P.05). During protrusion/retrusion movement, protrusion extent increase,the distance of condylar movement is bigger than normal occlusion(P.05). During lateral excursion, the trace in sagittal plane of the non-working side condyle is more incline than protrusion movement trace and the distance of the left non-working side condylar movement is larger than the right. During mediotrusion/right movement, the left biggest space distance is larger than normal occlusion and the transversal condylar inclination is smallar than normal occlusion when the distance of condylar movement is 5mm, the difference is statistically significant.

在开闭口运动时，双侧髁突运动幅度减小、位移量小于正常牙合者(P.05)；前伸后退运动时，前伸幅度增加，位移量大于正常牙合者(P.05)；侧方运动时，非工作侧髁突在矢状面上的轨迹较前伸轨迹向前下方倾斜度增加，非工作侧髁突空间位移左侧大于右侧，向右侧方运动中，左侧髁突空间位移大于正常牙合者，髁突位移5mm时水平面髁突倾斜度小于正常牙合者，差异有统计学意义。

在整个学习过程期间，教师和学生处于准永久性分离状态（以此与常规面授教育相区别）；教育组织在材料计划、准备和学生支持服务准备两方面的影响（以此与个别学习和自教计划相区别）；技术媒体（印刷媒体、视听媒体或计算机媒体）作为课程内容的载体，把教师与学生联系起来；提供双向通信，使学生可以主动对话并从对话中受益（以此与教育技术的其他应用相区别

First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.

首先，使用一种距离度量来计算混合矩阵每一类的类内类间距离比；然后对每一类按该比值由小到大重新排列混合矩阵和独立分量，保留权重矩阵中类间类内距离比大的列，及其对应的特征向量；最后对这些特征向量使用遗传算法选择最优特征组。
