查询词典 RF

Monolithic spiral transformers have been used in many microwave and RF ICs to perform impedance matching, signal coupling, phase splitting, etc.

单晶螺旋变压器已经应用於许多微波与RF电路上，其功能主要完成阻抗匹配、讯号耦合、相位劈列等等。

In this method, the excitation RF pulse is less than 90? no refocusing 180?

这种方法的射频脉冲小于90度，不需要重聚焦。

Recuring to the assistance from ADS , which is used for radio frequency simulating ,and general circuit simulating software - MULTISUM , several key technoledgeincluding RF signals disposing , local swept oscilating circuit , system control and frequency display etc. were discussed emphatically in the treatise . Not only the relevant theory but also the hardware circuit design were elaborated explicitly .

本文借助于射频模拟仿真软件ADS以及通用电路仿真软件MULTISIM，着重研究了弹道监测接收机的射频调理过程、本振扫频振荡技术、控制和显示技术等几个部分，在充分地探讨了相关理论的基础上，给出了相应的电路硬件设计。

Note that it's essentially at RF ground, shielding the remaining grids and the plate circuit from the oscillator portion.

应当注意的是它对射频是接地的，将振荡部分与其他栅极还有阳极屏蔽起来。

After amplying a 2.2kb fragment form the PPV-SC1 RF-DNA,we clone the fragment into pMD 18-T,named pTNSl.The whole sequence which is 1989 bp long was determined by sequencing, including the complete ORF of PPV-SC1 NS1 which encoding 662 amino acids.Alignment of pairs of sequence indicates that there are 98% and 99% similary with other porcine parvovirus strains Kresse and NADL-2, respectively. Multiple sequence alignment discloses that there are a few difference between ppv-scl nsl gene and other ppv nsl gene: A-G at 39nt,T-C at 153nt,A-G at 175nt, A-C at 1117nt, A-C at 1535nt .Alternative codon in ppv-scl nsl have distinctly different frequentfy by codonbias analysis at EMBOSS(http://genopole.toulouse.inra.fr/bioinfo/emboss). Thereis not distinct hydrophobicity and transmenbrane helices in ppv-scl nsl protein. Struction domain anslysis of PPV-SC1 NS1 protein indicate that there are a ATP/GTP-binding site motif A at 398-405,16 Protein kinase C phosphorylation site,21 Casein kinase II phosphorylation site,and 3 cAMP/cGMP-dependent protein kinase phosphorylation site.At the same time ,there is a same motif between ppv-scl nsl and Poxvirus D5 protein-like which may share in the same fuction which is necessary during virion duplication.

将PPV-SC1 NS1序列与其他PPV NS1基因进行多序列比对，结果显示，PPV-SC1 NS1与其他的PPV NS1的同源性较高，仅存在个别的差异，分别是第39位A→G，第153位T→C，第175位A→G，第1117位A→C，第1535位A→C；同源搜索比较表明，PPV-SC1与PPV NS1同源性可达98％、99％，与其他的细小病毒NS1基因也存在很大的保守性；密码子偏向性分析结果表明PPV-SC1 NS1基因在同一氨基酸的不同密码子的选择上存在一定的偏向性；PPV-SC1 NS1蛋白总体上说具有亲水性不存在明显的疏水性区段，用swiss TMPRED软件预测PPV-SC1 NS1的跨膜区，返回的结果并没有得到有显著意义的跨膜区的存在；根据基于motif数据库的结构域预测，PPV-SC1 NS1的第393-415位氨基酸残基存在潜在的ATP／GTP结合位点，该蛋白还存在16个蛋白激酶C磷酸化位点，21个酪蛋白激酶2磷酸化位点，3个cAMP-／cGMP依赖蛋白激酶磷酸化位点，PPV-SC1 NS1蛋白与POX_D5(痘病毒D5蛋白)具有一致的保守结构域，推测NS1可能与POX_D5有类似的功能。

Both the simulation and the experiment proved that kW-level rf power can drive the tube to generate GW-level output power

因此论文从实验和模拟两个方面，验证了kW级注入微波驱动的高功率微波放大器的可行性。
