The GKS stability theorem for one-dimensional model of hyperbolic initial and boundary value problem, Trefethen's explanation and extension based on the concept of group velocity are generalized firstly. Another possible high-frequency instability mechanism in numerical realization of MTF is pointed out based on his explanation and extension, namely, coupling effect of outgoing harmonic wave along one direction and node motion in the other directions can reverse the energy propagation in multi-dimensional discrete grids.

本文概述了—维双曲型偏微分方程组初边值问题数值稳定性的GKS定理及Trefethen基于群速度概念对这一定理的解释和推广；并应用Trefethen的解释和推广指出了MTF在数值实现中可能出现的另一种高频失稳机制，即在多维离散网格中，沿某一空间方向的外行简谐波，由于与其他空间方向节点运动的耦合效应可以使能量传播方向反向。

Generally, C extension modules are used to implement flat function libraries, and they wind up appearing as importable modules to Python code. C extension types are used to code objects that generate multiple instances and may optionally support expression operators much like classes.

通常，C扩展模块用来实现单一的函数库，它们对Python代码像是可导入模块。C扩展类型用来编写对象，对象可生成多个实例，可以支持表达式操作符，就像类。

Based on the analysis of tectonic deformation,extensional unconformity,sedimentary facies and paleogeographical rebuilding of southern Tibet,it is recognized that the extensional movement consists of active extension of Hercynian,Indo-Chinese and Early Yanshan epochs,and passive extension of the Himalayan epoch.

藏南特提斯域内伸展运动和伸展作用非常普遍，根据构造变形分析和伸展不整合、沉积岩相、古地理再造及岩相对比方法，对藏南海西期以来的伸展构造进行了较为系统的厘定，确定了海西期、印支期、早燕山期的主动伸展运动和晚燕山期和喜山期的被动伸展作用，并对这些运动特征进行了探讨。

In this paper,we give the representation of integral closure of a cubic extension about general Neotherian unique factorization domain (2,3 are not units). Then we give a series of integral number about a cubic extension.

本文在前人研究的基础上，去掉2，3可逆的这一条件，给出了诺特唯一分解环上的三次扩张的整闭包的描述，并由此刻画了一批该扩张下的整元。

By improving and rebuilding the previous mid-latitude model, we extend the model to high latitude and low latitude, respectively. The extension to high latitude mainly includes the effects of convection electric field and particle precipitation. The low-latitude extension primarily takes account of the configuration of magnetic field and interhemispheric coupling.

在对原有中纬电离层模型改造和重建的基础上，将该模型分别向高纬和低纬扩展，模型向高纬的扩展主要考虑了对流电场和粒子沉降的影响，模型向低纬扩展主要考虑了磁场位形、共轭半球的影响。

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。
