The 1-generator quasi-cyclic codes and their duals are the most frequently encountered QC codes in the literature. Séguin discusses the construction and the enumeration of 1-generator QC codes in the special case where the prime factorization of x~m — 1 is the same in IF_qn as in IF_q.

单生成元的拟循环码及其对偶码是拟循环码中研究最多的一种。Séguin在要求x~m-1在F_q及F_中具有相同的分解的条件下，讨论了单生成元的拟循环码的结构及计数。

Sequence analysis showed that the full-length cDNA sequence of Sc-SAMDC (GenBank Accession number: GQ246459) was 1 968 bp, with three open reading frames, tiny ORF, upstream ORF and main ORF. The mORF was 1200 bp encoding 399 amino acid residues with a molecular mass of 43.6 kD, and the deduced protein had two highly conserved function domains (proenzyme cleavage site and PEST domain).

序列分析显示，甘蔗Sc-SAMDC基因(GenBank Accession number： GQ246459) cDNA全长1968 bp，存在3个读码框（袖珍读码框tORF、上游读码框uORF和主读码框mORF），mORF长1200 bp，编码399个氨基酸的SAMDC酶原，预测分子量为43.6 kD，该酶原含有两个高度保守的功能结构域（酶原剪切位点和PEST结构域）。

The quantum quadratic residue codes are also extended in a nice way, most of which allow, the projective unimodular group, to act.

构造出量子二次剩余码的扩展码，与经典情形类似，对几乎所有的，量子二次剩余码的扩展码都以射影幺模群为自同构子群。

The generalized Reed-Solomon codes over the finite field F_q aremaximum-distance separable codes. This class of codes has optimal parameters.

利用有限域F_q中元来构造广义Reed-Solomon码，它是极大距离可分码，码的参数达到最优，但码的长度至多为q。

In addition, we also can provide customers tailored decoder read mode of operation, such as code does not read and re-issued a warning sound, limiting the length of read codes, special codes (for example, because of typographical errors have been truncated on both sides of the code)...

此外，我们也可为客户量身订作译码器的读取操作方式，例如重码不读及发出警告声，限制读码长度，特殊码(譬如因印刷错误被截掉左右两边的码)。。。

The invention discloses a method for dynamic channel allocation in TDD-CDMA mobile communication system. Based on the distance between mobile station and subzone base station BS, mobile stations MS are classified. Code tract in same group of code track (carrier frequency + time slot) is allocated to the mobile station with nearer distance. MS with different distances have different requirements of emission power. Whether crossed time slot code track group can be used or not, and use of group of code track with what kind of multiplexing factor need to be determined.

本发明公开了一种TDD－CDMA移动通信系统的动态信道分配方法，是将移动台MS按照与本小区基站BS的距离进行分类，同一个码道组中的码道分配给距离相近的移动台MS；同时不同距离的MS对发射功率的要求不同，对相邻小区的干扰也不同，系统根据MS对发射功率的要求，确定其是否可以使用交叉时隙码道组和使用哪种复用因子的码道组。

The study aims 1 to compare the performance of the rule-based tagger with that of the probability-based tagger; 2 to find out whether the performance of POS taggers is significantly affected by the quality of learnerlanguage; and 3 to discover typical errors of both types of POS taggers.

研究的目的在于：1比较基于规则的词性赋码器和基于概率的词性赋码器对中国英语学习者书面语的适用度；2考察学生作文质量对赋码准确率是否有显著影响；3分析两类词性赋码器在处理学习者语言时所暴露出来的弱点。

The Brill POS tagger and the CLAWS POS tagger were used to tag a group of high-proficiency learner texts and a group of low-proficiency learner texts, and tagging accuracy was then calculated.

研究中使用Brill词性赋码器和CLAWS7词性赋码器分别为一组高分作文和一组低分作文进行自动词性赋码，并统计赋码的准确率。
