查询词典 amplification

Spatial holeburning caused by ununiform widening of erbiumdoped fiber barricades the fully gaincontrolled amplification of laser with single wavelength. A novel configuration of automatic gainclamped optical erbiumdoped fiber amplifier is presented, and a high-birefringence fiber Bragg grating is used to generate pumping lasers, peaks of which are written at 1549.3 nm and 1549.83 nm with a wavelength spacing of 0.53 nm.

掺铒光纤非均匀展宽引起的空间烧孔现象导致单波长激光并不能完全控制放大器增益，提出了一种新颖的自动增益控制掺铒光纤放大器的结构：即采用高双折射光纤布拉格光栅产生抽运光，其写制光栅的波峰对应的波长分别为1549.3 nm和1549.83 nm，波长间隔为0.53 nm。

The universal primers of ITS1 and ITS4 for fungi were used in amplification of genomic rDNA sequences. A target fragment was obtained by ITS-PCR. Then, the fragment is cloned into the vector of pMD18-T before sequencing. The result of sequencing showed that the fragment is 692 bp in length. The results of Blast in Genbank and the analysis of fungal rDNA systemic development show that the relation between this fragment to the fungi of Sporisorium is closest, while the relation between it to the fungi of Ustilago is much far. It suggests that the name of Ustilago scitaminea for sugarcane smut isn't consistent to the result of rDNA systemic development analysis. It still needs more experiments to support this hypothesis.

用真菌rDNA序列分析的通用引物ITS1和ITS4，通过ITS-PCR得到目的片段，克隆在pMD18-T载体上后进行测序，结果显示该片段的长度为692 bp，与Genebank中已报道的真菌序列进行Blast和系统发育树分析，表明所获得的序列与Sporisorium属真菌具有更高的亲缘关系，而与Ustilago属真菌的亲缘关系较远，这与一直沿用的甘蔗黑穗病菌的命名似乎并不吻合，有待进行更多的研究以证实。

There are many specific words with special legal meanings in legal English. Moreover, the legal documents which stipulate rights and obligations must be precise, objective and standard disallowing any amplification or emotional expression, so many particular features of syntax are formed.

在法律英语中不仅有众多的具有法律专门意义的特殊词汇，而且由于规定人们权利和义务的法律、法令或契约等法律文书所表达的内容必须准确、严密、客观和规范，不容许丝毫的引申、推理或抒发和表达感情，因而在法律英语中又形成了许多特有的句法特点。
