空间同构

The structure theorem is obtained by defining "ternary ordered partition method" which is used to choose the test-sets of the first $k$ tests, and by defining two operations and two relations on feedback sequences; The isomorphism classification theorem is strictly proved by virtue of the structure theorem, thus the complicated problem of discussing $3^k$ possible search domains is reduced to the relatively easy problem on $k+1$ representative search domains; By the techniques of "super-coin construction method" and "image-union method", the search problem on $k+1$ representative search domains is reduced to the simple verification of several conditions on finite space of small cardinality.

通过引入用于选取前$k$次试验的试验集的"三元有序剖分法"以及关于反馈序列的两种运算和两种关系，得到了结构定理；基于结构定理严格地证明了同构类定理，从而将必须针对$3^k$个搜索域的复杂问题转变为讨论$k+1$个具代表性的搜索域的相对简单的问题；通过"构造超币法"和"并像法"等技术手段，将关于$k+1$个具代表性的搜索域的搜索问题转化为简单的关于势非常小的有限空间的几个条件的验证问题。

Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.

摘 要：应用混沌理论，分析了网络流量，用单变量的网络流量时间序列重构与网络动力系统等距同构的相空间，进而计算了实际网络的关维数和Lyapunov指数，并证实了网络流量存在混沌特性；据此建立了基于径向基函数神经网络的模型，并对实际网络数据流进行了预测。

We should form a tridimensional tourism traffic network with combination of highway/railage/ fight to realize the concordant development of tourism traffic, which should be consistent with the of scenic spots' layout.

实现旅游交通的协调发展要求构建由公路、铁路和航空等运输方式组成的立体旅游交通网络，在时间和空间上与旅游的景点分布结构同构、实现旅游客流的便捷通达；也要求通过有效的运输组织、实现运能与客流的方向和规模相适应。

We should form a tridimensional tourism traffic network with combination of highway/railage/ fight to realize the concordant development of tourism traffic, which should be consistent with the of scenic spots' layout. And also transportation organizing must adapt to tourism transportation flow.

实现旅游交通的协调发展要求构建由公路、铁路和航空等运输方式组成的立体旅游交通网络，在时间和空间上与旅游的景点分布结构同构、实现旅游客流的便捷通达；也要求通过有效的运输组织、实现运能与客流的方向和规模相适应。

It shows sufficiently that Miscellaneous Drama that describes thoughts provides special artistic value of discourse space for ordinary literati as well as for writer's wandering between elegance and vulgarness through manifold ways , such as the practice of expressing will and emotion , the special meaning revealed by autobiographic artistic expression and the natural artistic manner similar to essays of the late Ming Dynasty .

通过自我抒情言志和高扬主体精神的&写心&作法，因自传性艺术演述凸显出来的特殊意味，以及与晚明小品灵动自然，清新隽永之艺术格调的同构对应等，都充分显示出既徘徊于雅俗之间，同时又为普通文人提供了特殊的话语空间的艺术价值。

Several different ways of adding formulas are also discussed to eliminate symmetries, which will reduce the search space.

还讨论了通过增加公式来消除同构从而减小搜索空间的一些方法。
