The trinomial property of sequence In the respect of research on trinomial property of sequence, I have given a different proof to prove the main result in [2] , and have raised the exact enumeration formula of the number of binary sequences with period d that have a fixed positive integers pair as a trinomial pair, most important of all, I have given an efficient algorithm to find out all the trinomial pairs of a given sequence, and hence completely solved all the problems associated with trinomial property of sequences.

2序列的三项式特性在序列三项式特性的研究方面，本文对[2]的主要结论给出了不同的证明，而且给出了以固定的正整数对为三项式对的周期为d的二元序列的精确计数，给出了求解给定序列的所有三项式对的有效算法，从而完美地解决了与序列三项式特性相关的问题。

The change phase is estimated by window and interpolation algorithm, and then a phase compensation function can be built accordingly. By multiply this function and the data sequence from the IFFT of the truncated data sequence spectrum in the time domain, the spectral leakages can be compensated when the new data sequence is transformed into the frequency domain by the DFT.

利用加窗插值的方法估计出该变化的相位，并利用估计结果构造出一相应的反相位函数，在时域上将这个反相位函数与由傅立叶反变换产生的离散序列相乘，得到新序列再通过一次傅立叶变换就可达到频谱校正的效果。

Methods MtDNA was successfully extracted from Turki human remain. Through four overlapping primers, the nucleotide sequence of 360 bp length was gotten. Then it was contrasted with the cambridge reference sequence, and the sequence was analyzed with that of Khitan nobles basing the methods of phylogenetics.

对吐尔基山辽墓出土的人骨遗骸进行mtDNA研究，使用4对套叠引物对线粒体第一高可变区(360 bp)进行扩增和测序，利用契丹贵族人群的相关序列，对所得序列进行分子系统学分析。

An unbounded sequence of indexes is trivial to write, and a reusable instance of that sequence can be passed to zip, in parallel to the sequence being indexed.

写一个未绑定的索引的序列是没有价值的（对这个xrange是方便的）。并且那个序列的一个可重用的是列能够被传递到zip，并行的这个序列被索引。

In this paper a decision method of uniform convergence for function sequence is given, and a few of properties for the uniformly convergent function-sequence are obtained by this method, which is used in the construction of a new uniformly convergent function-sequence by others known.

给出了一个定理用于判定函数列的一致收敛，通过此判定定理，又得出了由一致收敛函数列构造新的一致收敛函数列的几个性质。

The BLAST programs were used for searching protein and DNA databases for sequence similarities. The BLAST result showed that it was a new sequence and similar to zebra fish DNA sequence and some fish reverse transcriptase. But it has small homology of CYP 19 gene sequences that have been in Genbank.In addition, sequences were amplified by RT-PCR with using degenerate primers that weredesigned against CYP4 sequences.

另外，还根据昆虫CYP4家族的特异性氨基酸序列及P450超家族的共同特征序列，采用另一对简并引物，同样进行有关研究，结果显示：疣荔枝螺不同组织的RNA中都含有一长468bp左右的序列，这同样是一段新序列，与部分物种的CYP4存在一定的相关性，可能在螺体内起一定重要的作用，但具体功能有待进一步研究。

The elements of each sequence in odd-periodic perfect almost binary sequence pair are "1" or "-1" with exception of a single zero element, and odd-periodic perfect almost binary sequence pair possess a perfect odd-autocorrelation function.

奇周期最佳几乎二进序列偶中2个序列中均有一个元素为"0"元素，其他元素取值均为"＋1"或"－1"，并且其奇周期自相关函数为单值脉冲函数。

Pilot zero sequence directional protection may fail to operate because the zero sequence current on one end does not reach the set value of the protective relay,although zero sequence directional elements on both ends operate correctly.

线路发生接地故障时，两侧零序阻抗相差过大将导致两侧零序电流差别过大，虽然两侧的零序方向元件均能正确动作，但是由于一侧零序电流达不到动作定值，从而造成纵联零序方向保护拒动。

Because of sharing characteristics with both Galliform groups, Tragopans are classified as partridges by some authors and pheasants by some others. In this study we set out to sequence the cytochrome b-gene of 19 species pheasants. and took the sequence for those 22 species from GenBank. We amplified 828 base pairs using the PCR technique. Primers designed by ourselves were based upon Galliform sequence data. Neighbor-joining method and Minimum evolution method were used to analyse cytochrome b sequences with Anhima cornuta and Kachuga dhongoka as outgroups.

通过PCR扩增鸡形目Galliformes黄腹角雉Tragopan caboti等10个属19个个体的线粒体DNA细胞色素b的部分基因，获取片段长度为828bP，以及从GenBank获取22种样本的相应序列，以角叫鸭Anhima cornuta和海龟Kachuga dhongoka为外群，分别用邻接法(Neighbor-joining， NJ)和最小进化法(Minimum-evolution， ME)，对鸡形目和将雉科的15个属分为5个属及雉族和鹑族构建分子系统树，NJ和ME系统树中，都是角雉与雉类相聚。

Analyzing by blastn program of NCBI, the fragment includes: 30bp 12srRNA partial sequence, 71bp tRNA-Val complete sequence and 913bp 16srRNA partial sequence, and the homolog is more than 95 % compared with other Camelidae animals.
