间隔子

If sexual intercourse must happen, then it should be for the sole purpose of begetting children and presumably at long intervals.

如果必须要的话，只能是为了得到子嗣的唯一目的而且大概得长时间的间隔。

Despite the channel is not smoothly,but each sub channel is smoothly and the signal be transferred by narrowband in sub channel,which can avoid disturber between sigal wave.

本文的研究表明，如果采用新的正交基来取代这些子载波，可以在不加保护间隔的情况下减少ICI和ISI，从而改进正交频分复用技术的性能。

Also,they can be used widely because of the high homology wit other species.

这两个片段都是从基因的外显子中获得，中间没有内含子间隔。

Phylogenetic relationships among the 18 original genera of the palm family were investigated using two DNA sequence data sets derived from matK, the maturase - coding gene located in an intron of the plastid gene trnK, and the internal transcribed spacer region of 18S-26S nuclear ribosomal DNA to examine relationships in 18 generas of chinese palm family.

通过叶绿体trnK基因的内含子matK序列及核糖体转录间隔区序列研究初步分析了中国原生棕榈科18属间的系统发生。

Cloning and sequencing of the genes coding a and 3 subunit of phycoerythrin of a red alga-Corallina officinalis are reported firstly(GenBankaccession number: AF510986). The sequence contain 1,140 nucleotide, including 10 nucleotide that locate in the upstream of the initiation codon ofP subunit, 534 coding for P subunit(coding 177 amino acid), 101 nucleotide for gene spacer and 495 nucleotide that draw near the 5 terminal of a subunit(coding 164 amino acid).

首次测定了珊瑚藻藻红蛋白α和β亚基基因的全序列(GenBank登录号：AF510986)，测定的基因序列长为1，140个碱基，包括β亚基起始密码子上游的10个碱基，6亚基编码区的534个碱基(编码177个氨基酸)，101个碱基的间隔区以及α亚基编码区近5'端的495个碱基(编码164个氨基酸)。

It shows that theintrons or spacer of these two organisms may have the same ancestor.

这一结果表明上述两种植物中的这些内含子或间隔区可能从同一祖先进化而来。

The sequences of segments of the trnL intron from 29 species and trnL-trnF IGS from 21 species of Magnoliaceae were analyzed. The results from the strict consensus trees were consistent with the former systems ① several species within the genera Michelia were homologious;② the subgenera Yulania was extremely homologious and much far from subgenera Magnolia;③ the species within Manglietia were highly conservative.

通过木兰科29个种的trnL基因内含子的525个碱基序列及21个种的trnL-trnF基因间隔区的370个碱基序列测定和分析，构建的严格一致性树建议：①含笑属为相对一致的单系类群；②玉兰亚属的几个种形成一个单系类群，与木兰亚属的几个种无共衍位点；③木莲属为个相对保守的类群，种间碱基差异很小。

At the same time, it shows that the intervening sequence between transcriptional terminator T φ and translational stop codon TAA has no significant influence on TGF β1 expression.

同时发现，转录终止子Tφ与翻译终止密码子TAA之间的间隔序列对TGFβ1的表达没有明显影响。

On the other hand, OFDM is very sensitive to carrier frequency offset and frequency spread for the increasing symbol period or the small subcarrier internal, which result in serious intercarrier interference , and the performance of OFDM system is greatly affected.

另一方面，OFDM符号周期相对增加即子载波间隔的减小会使得OFDM系统较单载波通信系统对载波频率偏移或Doppler扩展更加敏感，使子载波之间的干扰增加，影响系统的性能。

This corresponded to a phonon amplification effect. The mechanism of generating the phonon amplification was discussed.

详细讨论了产生这种声子增益效应的机理，给出了产生声子增益的时间间隔。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
