Question

本人英语水平不好，求高手帮忙翻译下下面一段话，急啊！谢啦！

要翻译内容 " 鉴于热释电探测器信号源幅度小、阻抗高的特点，需要利用前置放大器进行阻抗变换、信号放大以及预处理，以便满足后续电路对信号处理的要求。本文使用分立元件和集成运放搭配设计了一款高增益、低噪声的前置放大器。文中对热释电探测器前置放大器中的产生噪声因素进行了分析，给出了降低噪声的一些方法，并用multisim软件对电路进行了仿真测试，其结果表明本文设计的前置放大电路能有效放大热释电探测器的微弱信号。"
拜托 别在线翻译！那我也会！有专业的吗？

Answer 1

In view of pyroelectric detector signal amplitude is small, impedance high characteristic, need to use the preamplifier makes impedance transformation, amplification and pretreatment, in order to meet the follow-up circuit for signal processing requirements. This paper used division components and integrated amp collocation designing a new high gain the preamplifier, low noise. In this paper the pre-amplifier pyroelectric detector the noise factors are analyzed, some methods to reduce the noise, and for circuit multisim software simulation test, the result shows that this design preamplifier can effectively amplification pyroelectric detector's weak signal.

In view of the pyroelectric detector signal amplitude is small, the characteristics of high resistance, need to use pre-amplifier for impedance conversion, signal amplification and preprocessing in order to meet the follow-up circuit for signal processing requirements. This article uses discrete components and integrated operational amplifier design with a high gain, low noise preamplifier. In this paper, the pyroelectric detector preamplifier noise factors in the analysis, given some of the ways to reduce noise, and use multisim circuit simulation software, testing, and the results show that the design of the preamplifier circuit can effectively pyroelectric detector amplification of weak signal.
希望能帮你哈！这应该是对的！

Answer 3

Owing to the thermal releases to give or get an electric shock the finder semaphore source amplitude small, impedance high characteristics, need to make use of the impedance transform, semaphore of the preamplifier progress to zoom in and prepare a transaction, in order to satisfy follow-up telephone vs the request that the semaphore handles.This text use was separate component and integration luck to put to match to design a style of high gain, low noisy preamplifier.Release to give or get an electric shock creation Zao within finder preamplifier a voice vs the thermal in the text the factor carried on analysis and gave lower a little bit noisy methods, counteract the multisim software carried on to imitate vs the telephone true test, it expresses this text to design as a result of previous place the tiny weak signal that the big telephone can effectively zoom in thermal to release to give or get an electric shock finder

Answer 4

Since the characteristic pyroelectric detector signal amplitude is small, highly resistant, need to use pre-amplifier for impedance conversion, signal amplification and preprocessing in order to meet the follow-up circuit for signal processing requirements. This article uses discrete components and integrated operational amplifier design with a high gain, low noise preamplifier. In this paper, the pyroelectric detector preamplifier noise factors in the analysis, given some of the ways to reduce noise, and use multisim circuit simulation software, testing, and the results show that the design of the preamplifier circuit can effectively Pyroelectric detector amplification of weak signals.
