Question

谁能帮我翻译一下这段话，我有急用，谢谢！

直流稳压电源一般由电源变压器，整流滤波电路及稳压电路组成。变压器把市电交流电压变为所需要的低压交流电。整流器把交流电变为直流电。经滤波后，稳压器再把不稳定的直流电压变为稳定的直流电压输出。本设计主要采用CW317稳压芯片构成集成稳压电路，通过变压，整流，滤波，稳压过程将220V交流电，变为稳定的直流电，并实现电压可调。正负电源发生部分利用NE555集成电路构成单电源变为双电源的电路。
请不要用软件翻译，谢谢！

Answer 1

DC power supply from the general power transformer, rectifier circuit filter and regulator circuits. Transformer Urban AC voltage electricity into low-voltage need AC. Rectifiers put AC into DC. After filtering, Regulators then the DC voltage instability into a stable DC voltage output. The design used mainly CW317 Regulators Chip Integrated Circuit Regulators, PSA, rectifier, filtering, the process will Regulators 220V AC into DC stability, and achieve voltage adjustable. Positron Power NE555 partial use of the IC into a single power-supply circuit.
