一、巧脱“锅巴”煮饭时 ,免不了锅底有锅巴 (又称焦巴 ) ,有时费劲不少也难以把它从锅底脱去 .若采用下列办法 ,则能巧妙地将锅巴脱去 .当饭熟离开火源时 ,马上将其置于地板上 ,冷却一段时间后 ,再打开锅盖 ,这样 ,锅巴会极易脱去 .利用的原理就是物理学中的“热胀冷缩”现象 First, clever “pan” cooking rice, inevitably have a pan at the bottom of the pan (also known as Jiao Ba), sometimes hard and difficult to take it off from the bottom of the pot. When cooked leave the source of fire, immediately put it on the floor, cool down for a period of time, and then open the lid, so that the pot will be very easy to take off the principle of use is the physics of “thermal expansion and contraction” phenomenon
