您家里用电的家什是越来越多了。说真格的,谁家里没有电灯电扇,冰箱彩电呀！要不然干嘛把现今世界叫作电子世界啊。对于形形色色家用电器的购置,必须力求造型美观、质量上乘、坚固耐用,这些都是人所共知的道理。但是怎样合理地去连接这些电器的供电电源电路,却往往被人忽视。随便举两个例子吧。 There are more and more households that use electricity in your home. Really speaking, who does not have a lamp at home, refrigerator color TV it! Otherwise why do you call the world today the electronic world? For the purchase of all kinds of household appliances, we must strive for beautiful appearance, superior quality, and sturdiness and durability. These are the principles we all know. However, how to reasonably connect the power supply circuits of these appliances is often overlooked. Just give two examples.
