"            随着人类社会不断发展，进步，人们对生活的要求越来越高，年轻的妈妈对小宝宝甚爱有加。为让宝宝有一个温馨，舒适的摇篮，我们特设计了“小儿尿湿报警器”。它" 
"   可使小孩尿布尿湿后得到及时更换，消除了婴儿感染尿布湿疹的隐患。在小儿尿湿后 ，发出“嗡嗡  ——嗡嗡”的报警声。下面是设计线路，原理和技术指标：" 
"        技术指标：直流电源电压：6V，功率：500mW. " 
"         要求：体积小，成本低，使用方便。  " 
"             本电器是由电源，开关驱动电路，功率输出电路三部分组成。电源可用四节5号电池，不用时开关K2断开。" 
"              仿真方案：首先按1键，打开电源，然后按空格键（相当于有一微小信号，即小儿尿湿 ）。就会发出警报声。   "
