In the second chapter, we investigate propagations of desynchronous disturbances in synchronized chaotic one-way coupled map lattices. It is well known that spatiotemporally chaotic systems with large gradient couplings may show convective instability under the absolute stability condition of chaos synchronization. This convective instability is the key reason for the effective propagation of control signals.

时空混沌在不同的耦合系数情况下会表现出不同的动力学行为，用驱动实现具有强梯度耦合系数的时空混沌同步时，会观察到在绝对稳定条件下被驱动系统表现出对流不稳定性，这种对流不稳定性是在单个信号驱动下实现混沌同步的关键原因。

Finite-difference time-domain method was used to simulate the coupling processes of ultra-wide-band electromagnetic pulses into a cavity with a slot, and an anisotropic perfectly matched layer absorbing medium was inserted to truncate the computational lattices.

为便于讨论合金元素对Fe3Al合金缺陷组态和电子密度的影响，我们把Fe、Cr、Mo和Al的电子构型、晶体结构、原子半径、电负性[10]及正电子在其金属基体中的寿命值[11，12]列于表4。

The one-way coupled map lattices and initial condition generation function based on iterative Logistic map are used to realized the data confusion and diffusion between plain-text and key information. And the cipher block chaining mode is used to generate the 128-bit Hash value for plaint-text with arbitrary length.

该方法通过使用单向耦合映射格子和基于迭代Logistic映射的初始状态生成函数实现明文和密钥信息的混淆和扩散，并基于密码块连接方式产生任意长度明文的128位Hash值。

The course contains four sections as follows: mathematical logic (including basic concepts of propositional logic and predicate logic, propositional calculuses and inference theories), set theory (including set algebras, relations, functions and cardinal numbers), algebraic structure (including algebraic systems, semigroups and groups, rings and fields, lattices and Boolean algebras), graph theory (including basic concepts of graph, Euler graphs and Hamiltonian graphs, trees, planar graphs and coloring graphs, some special vertex subsets and edge subsets).

本课程包含四部分内容：数理逻辑（包含命题逻辑与一阶逻辑的基本概念、等值演算以及推理理论），集合论（包含集合代数、二元关系、函数和基数），代数结构（包含代数系统、半群与群、环与域、格与布尔代数），图论（包含图的基本概念、欧拉图与哈密顿图、树、平面图及图的着色、图的某些特殊的顶点子集与边子集）。

Based on the horizontal and vertical combination in formal contexts, this paper defines the independent or consistent contexts and lattices in attribute field; and also defines the horizontal addition operation between contexts or concepts and the horizontal union operation between concept lattices. In addition, we prove that the concept lattice of subcontexts horizontally combined is isomorphic to the horizontal union of sublattices of these subcontexts.

本文首先从形式背景的纵向、横向合并出发，定义了内涵独立和内涵一致的形式背景和概念格；还定义了内涵一致的形式背景、概念的横向加运算和概念格的横向并运算，并证明了横向合并的子形式背景的概念格和子背景所对应的子概念格的横向并是同构的。
