求英文高手翻译 （中翻英）急!在线等
两个NPN晶体管T1和T2和T3是一个PNP晶体管配置为一个高度敏感的电压放大器.
这种配置仍然使用了录音机前置阶段意识和健全的微小磁性回升来自磁头的信号.它执行相同的功能在这里是用来放大从一个小的压电式蜂鸣器B1的电信号.
压电蜂鸣片通常转换成声音输出电压的电气振荡.但在这条赛道上它是在有线运作方式正好相反.在这里,它是用来感知外部声音的振动,并转换成电脉冲他们.
在得到适当阶段,通过晶体管放大,这些脉冲被筛选和电容C1平滑,并最终达到一个阶段闭锁电路的晶体管T4和T5组成.
在接到感觉到输入脉冲,接收所需的晶体管T4的偏置,并立即进行.
晶体管开关粘数也即刻到期,通过T4的接收到的基地电压.在同一时刻一个反馈电压送回基地的T4由粘数和锁存电路触发报警和良好的外部电路.在车用喇叭警报器的类型可以是用在这里.
启动报警声音可以停止只有关掉装置.

Two NPN transistor T1 and T2 and T3 are a PNP transistor disposition are a highly sensitive voltage amplifier.
This kind of disposition has still used the tape recorder pretage stage consciousness and the perfect small magnetic rise comes from the magnetic head signal.It carries out the same function is uses for in here to enlarge from a small piezoelectricity type buzzer B1 electrical signal.
The piezoelectricity buzzing piece usually transforms the sound output voltage the electrical vibration.But on this racecourse it is in the wired operation way just right opposite.In here,it is uses for the sensation exterior sound the vibration,and transforms the electricity pulse they.
Is obtaining the suitable stage,enlarges through the transistor,these pulses are screened and electric capacity C1 are smooth,finally and achieves a stage exclusive circuit transistor T4 and the T5 composition.
Is receiving felt the input pulse,receives the transistor T4 bias which needs,and carries on immediately.
The transistor switch sticks the number also instantly to expire,through T4 receive base voltage.Returns to the base in an identical time feedback voltage T4 by to stick the number and the lock saves electric circuit triggering to report to the police with the good exterior electric circuit.May be uses in the vehicle with the loudspeaker alarm type in here.
The start reports to the police the sound to be possible to stop only then switching off the installment.
