查询词典 emitter

With this mode of working the base-emitter circuit is the input side;and the emitter through base to collector circuit the output side.although these have a common path through base and emitter, the two circuit are effectively separated by the fast that as far as polarity of the base circuit is concerned,the base and upper half of the transistor are connected as a reverse biased diode.hence there is no current flow from the base circuit into the collector circuit.

这一工作模式下，基极-发射极电路是输入端，发射极通过基极，再到集电极电路的输出端。虽然它们都有一个共同的路径通过基极和发射极，这两个电路是通过和基极电路相关的尽可能的有效快速分离开的，基极和基极以上的一半以上的晶体管作为一个反偏二极管与之相连接。

For weak nonlinear distortion, the expressions of total harmonic distortion, the second order intermodulation distortion(IM2 ), the third order intermodulation distortion(IM 3) and intercept point(IP 3) are deduced. With the aid of software Multisim, we simulate transistor common emitter amplifier, transistor common emitter amplifier with resistor in emitter, differential amplifier and differential amplifier with resistor between emitters. The simulational results and theoretical analyses are almost the same.

针对弱非线性失真，推导了总谐波人、二阶互调失真( IM2 )、三阶互调失真( IM3)和截点( IP3)的表达式，借助于 Multisim软件，对晶体管共发放大器、发射极带反馈电阻的失发放大器、差分放大器和发射极间带反馈电阻的差分放大器进行了仿真，并与理论结果作了比较，结果令人满意。

Current flow between the emitter and base controls the current flow between the emitter and collector.the emitter of the transistor is the most heavily doped so it has the most excess electrons or holes.

由发射极到基极间的电流控制发射极到集电极间的电流，晶体管的发射极是重掺硅型的，所以它有过量的电子或空穴。练习翻译？遇到难题？快来翻吧

It is found that the utilization of BAlq3/Alq3 isotype heterostructure emitter further reduces the leakage current, leading the BAlq3/Alq3 isotype heterostructure-based devices to higher output current and higher common-emitter gain at the same operational voltage compared to the case of Alq3 as the emitter.

研究发现，同Alq3单发射极层结构的金属基极晶体管相比，BAlq3/Alq3异质结发射极层的使用进一步降低了器件的漏电流，使器件在相同的电压下表现了更高的输出电流和更高的共发射极增益，为进一步实现高性能金属基极晶体管提供了新的方法。

It is shown that in the small distance region of the bar-LD the intensity distribution of the bar-LD is constructed by separate beam spots emitted from each emitter. As the distance of the observation point from the bar-LD increases, the beam spots of the emitters begin to overlap, and even to form a flattop distribution in a large distance region.

结果表明，在距发光面较近处，各emitter辐射的光斑呈分离状；随着距离增加，各光斑开始交叠，甚至出现平顶；当距离足够远，bar型半导体激光器的远场光斑与单个emitter的辐射光斑几乎没有差异。

The ordering parameters of GaInP are deduced from the polarization dependence {E||[110] and E||[1 0]} of the PR signals from the emitter regions. The ordering related piezoelectric fields are found to influence the electric field, as evaluated from the observed Franz-Keldysh oscillations, in the GaInP region. According to the experimental data of the as-grown GaInP/GaAs/GaAs samples, we find that for the same emitter doping level the emitter field in the more ordered materials is smaller than in the less ordered sample.

经由分析A系列样品的FKOs信号，估算出射极/基极区域的内建电场，加上极化实验的结果，可以估计磷化铟镓的有序程度；因为压电场的关系，发现当GaInP能隙越小时，内建电场也会跟著降低；温度变化实验，验证其内建电场会随著温度增加而变大，只是变化量不甚明显；利用Varshni及Bose-Einstein方程式来估计一些与温度相关的参数值，并与相关文献比较，其结果颇为相符。
