"           自39班  22號  莫岸華" 
"            電路名稱：延時門鈴開關電路" 
"            技術指標：" 
"                    電     源：220V/50HZ" 
"                     變壓器：pq3-24" 
"                     buzzer: 200HZ/12V/0.05A" 
"                     顯示：七段碼管" 
"                     延時：6秒" 
"              電路特點：簡單，易懂" 
"              電路原理：                " 
"" 
"                         當按下延時開關時，電路接通，電鈴和顯示管開始工作，" 
"                 導通時間由延時開關調節(jié)?？砷L可短。它的顯著特點是只要按下" 
"                 開關，電路就能連續(xù)工作。無需用手一直按著開關。"
