查询词典 tracing rut

As applications, we prove the following results: If / has pointwise pseudo-orbit tracing property, for any k ∈ Z+, and fk is chain transitive, then for any k ∈ Z+, fk has open set transitive ; If f has pointwise pseudo-orbit tracing property, and for any n ∈ Z+,fn is chain transitive, then f has sensitive dependence on initial conditions; If f is open set mixing and has pointwise pseudo-orbit tracing property, then f has property P; Let f :→ be a homeomophism, then f is pointwise pseudo-orbit tracing property if and only if the shift map σf is pointwise pseudo-orbit tracing property.

作为应用，证明如下结论：若f具有逐点伪轨跟踪性质，且对任意k∈Z+，fk为链转换的，那么对任意k∈Z+，fk为开集转换；若f具有逐点伪轨跟踪性质，且对任意n∈Z+，fn为链转换的，则f具有初始敏感依赖性质；若f为开集混合的，且具有逐点伪轨跟踪性质，那么f具有性质P；设f：→是同胚映射，那么f具有逐点伪轨跟踪性质当且仅当移位映射σf具有逐点伪轨跟踪性质。

平面向量场与曲率分析在曲面求交中的应用宁涛，马德昌，王亚平，唐荣锡（北京航空航天大学制造工程系北京100083）摘要在曲面求交算法中，初始跟踪点的确定和交线分支的跟踪是最关键的两个问题。

In the process of contour tracing, contour lines are gained by tracing in anticlockwise order and a method of backdate search which ensures the correctness of the algorithm is used for contour tracing at those pixels where other contour pixels can not be continuously traced. By analysis of the neighbouring pixels, this paper avoids judging those pixels that no need to be compared again.
