查询词典 extension

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。

This new model has some advantages, such as assuring IRDS's advancement, extension and engineering realization in the existing computing circumstances, which makes IRDS good opening ability, extension and adaptability.

这种新模型有利于保证IRDS的先进性和发展性及在现有计算环境下的工程实现性，将使IRDS具有良好的开放性、扩展性和适应性。
