This paper has proposed the following explanation for this topic based on Social Couplings by Maturana, a cognitive biology scholar, organic view by Cooley, a symbolic interactionist , and model of a system in equilibrium by Argyle, a social psychologist:(1) the interaction is an act sequence of "hint-choice";(2) All the teacher and students in mathematics classroom have contributed to the formation and modification of consensual domain;(3) consensual domain in mathematics classroom is not an independent reality;(4) teacher and students' perception to consensual domain in mathematics classroom shall guide their behavior;(5) The coupling standard of consensual domain is not fixed for all observers;(6) the effect of mathematics enculturation should be reinterpreted.

本文整合认知生物学学者Maturana的社会耦合理论、符号互动论学者Cooley的有机观，以及社会心理学者Argyle的均衡系统模型，对共识域之本质与功能提出下列解释作为回应：(1)数学教室内的互动是一「暗示—选择」的行为序列；(2)师生皆对数学教室系统共识域之成型与改变有所贡献；(3)数学教室系统内的共识域并非独立於观察者之客观实在；(4)师生个体对数学教室系统共识域的知觉会指引师生的个体行为；(5)观察者描述数学教室共识域的耦合标准有狭义与广义之分；(6)数学文化传承的必然性应予重新解读。

We make use of a normal element and circular permutations to construct polynomials over the intermediate extension field between F_q and F_ denoted by F_ where s divides t. The polynomials we constructed are F_q-linearly independent and return elements in F_q when they are evaluated at elements of the extension fields.

结合Reed-Solomon码的构造特点，我们将Chaoping Xing与San Ling所构造的线性码的方法推广到有限域的任意次扩张上，首先利用正规元和循环排列来构造系数属于F_q和F_q的任意次扩域F_之间的中间域的具有特殊性质的多项式，中间域记为F_，其中s为t的真因子，由正规元的选择可以保证所构造多项式的F_q-线性无关性，并且这些多项式在扩域F_中取值都属于F_q，从而构造出一类q元线性码。

In an visibility analysis sight, expressed avoids in this scenic spot sight scope planted agent constructing some not beautiful artificial facility or carrying on the artificial destruction, but may establish some appropriate artificial scenic spots, builds the scenic forest and so on; The line sight is a set which regards by the innumerable spots is composed, because the traffic lane is the tourist mainly watches during the route, in its sight scope landscape exquisite degree has directly affected scenic area comprehensive esthetic sense; Two intervisibility, contained two scenic spots respectively to see the region scope, as well as building the exquisite landscape in the public sight.

可视性分析中的一点视域，表示在这个景点视域范围内应避免建设一些不美的人工设施或进行人为破坏，但可以设置一些合适的人工景点，营造风景林等：线视域，可以看作是由无数个点视组成的集合，因为车道是游人的主要观赏路线，其视域范围内的景观优美程度直接影响了景区的综合美感度；两点通视，包含了两个景点各自看到的区域范围，以及在公共视域营造优美景观。

The invention relates to a method for synchronizing at least one node of a bus system, which is operated with a predeterminable system clock period, whereby a local clock period and a reference clock period are given for the at least one node, and the reference clock period is synchronized with the system clock period. A local clock period, which is synchronized with the system clock period, of the at least one node is produced whereby linking the local clock period with a splitting factor, whereby the splitting factor represents a ratio of the reference clock period to the local clock period. The splitting factor for synchronizing the local clock period with the system clock period is adapted by adding or subtracting a adaptation value.
