在线翻译的就不用回答了.
OOXX，第一个，你是在有道上翻译的。第二个，你的几乎跟谷歌翻译的一模一样。就是最后一句变了。
人心不古，世风日下啊！
摘要改了，现在是酱紫的：
本系统以单片机AT89S51最小系统为控制模块，采用高性能低噪音运算放大器NE5532和 CMOS 双二阶通用开关电容有源滤波器MAX262来完成可控放大器的设计，放大部分为了达到60dB增益可以采用两级放大，第一级先放大2倍，第二级利用模拟开关CD4051通过单片机编程来改变反馈电阻阻值，从而改变放大器电压增益，总的放大倍数为第一级与第二级放大倍数的乘积，这样就可实现电压增益从10dB到60dB可调步距为10dB，此种方法通用性强，经济实惠，效果显著，而且电路放大倍数精确、易控制、调节范围大。滤波器部分的高通、低通和带通可通过开关来切换，通过单片机对可编程滤波器芯片MAX262的中心频率f0和品质因数Q进行独立编程控制，实现对滤波器的截止频率在1kHz～20kHz范围内可调，调节的频率步进为1kHz。
英语高手们都来救救小弟吧！后天就要给指导老师看了，不然的话……会死的很残的！谢谢高手赏脸！
