查询词典 topological dimension

From the dimension of economical philosophy, the two various philosophical keys showed by The Poverty of Philosophy and The Philosophy of Poverty determine the dividing line of the economical idea of Marx and Proudhon; German classic philosophy, especially Hegel's dialectic, was not only the object criticized and relied on by Marx, but also became the philosophical basis of Proudhon's economy; Proudhon, however, with dialectical intuition, developed the dialectique serielle that was analogous to Hegelian dialectic of idealism.

从经济哲学视域看，《哲学的贫困》与《贫困的哲学》展现出的两种不同的哲学基调，决定了蒲鲁东与马克思的经济学理念的分野；德国古典哲学，特别是黑格尔的辩证法，不但是马克思所批判和仰赖的对象，而且构成了蒲鲁东经济学的哲学根基，不过蒲鲁东凭借辩证的直觉提出的系列辩证法是类似于黑格尔的唯心主义辩证法。

Based on the return map and the principle of closed vectors, a new method is proposed to extract unstable periodic orbits embedded in chaotic attractors. As examples, the UPOs embedded in chaotic attractors of Logistic, Hénon and Lorenz are extracted respectively by this method. And our results of Skewed Hénon map also be compared with Nusse's. These results suggest that this method is valid for unstable periodic orbits from period one to period infinite of arbitrary dimension chaotic system. The dynamic considerations of spiking and UPO coding for individual neuron and neural system under external periodic and chaotic exciting stimulus also be studied in this dissertation. A lot of spiking phenomena, such as synchronization, period, and chaos appear alternatively with the changing of the stimulus frequency. For the small stimulus frequency the neuron could completely convey the periodic signal in synchronous anti-phase into interspike intervals sequences. For the slow time–scale chaotic input, the output two ISI sequences are reciprocally related to input signals, and their oscillation wave shape in time course can be derived from that of the input signals variation, furthermore, the similar input sequence and order of UPOs, distribution of LES and value of KYD remain in attractors reconstructed from ISI sequences.

发现周期信号在单个神经元传递过程中，随着激励频率的改变，神经元输出的峰峰间期interspike interval时间序列呈现出周期、混沌和准周期的交错变化，特别当外加激励信号频率较低时，周期信号可以通过神经元ISI序列以反相同步的周期运动形式传递下去；同时无论是周期还是混沌激励信号，在神经系统中的传递均与其自身强度和神经元之间的耦合强度的大小密切相关；快变时间尺度的混沌激励信号在耦合的神经系统传递过程中，会造成大量基本信息的丢失；而慢变时间尺度的混沌激励信号在神经系统传递中，它的非线性特征信息，如混沌吸引子、不稳定周期轨道、Lyapunov指数谱和分形维数，会通过系统输出的ISI序列部分地重现出来，如与输入慢变时间尺度的混沌激励信号相比，神经系统输出的ISI序列具有：相似几何形状的混沌吸引子、相近的Lyapunov指数谱和分形维数、局部结构相同的不稳定周期轨道的排列方式。

In the subsequent experiments, when the LaBe cathode emitted continuously and the current is 40uA, the minimum diameter of electron-beam spot recorded was 22 um. While the LaB6 emitted pulse, the minimum diameter of the focus decreased and wasnt more than 15um. The reason is that the heat accumulated on the foil-film, which enlarged the focus dimension, reduced remarkably.

当阴极采取连续发射电子的工作模式(发射电流40μA)时，记录测量到的最小电子束焦斑直径不大于22μm；而在相同条件下，以脉冲方式发射电子束时，其焦斑直径不大于15μm，原因是短时间的电子轰击减小了靶面的热堆积效应等。
