燃烧蜡烛水中悬浮现象的研究
|
摘要
对燃烧蜡烛在水中悬浮的机理进行了理论与实验探究.通过建立近似垂直井结构模型,从辐射能流的角度对蜡烛的整个燃烧过程进行了理论分析.并且从实验上探究了蜡烛长度、蜡烛半径、以及配重对于蜡烛悬浮过程的影响.最后还对其振动模式进行了分析.
The mechanism of burning candle in water is investigated theoretically and experimentally.By establishing an approximate vertical well structure model,the whole burning process of candles is analyzed theoretically from the angle of radiant energy flow.Then the effects of candle length,radius and counterweight on the suspension process of candles are investigated experimentally.Finally,the vibration mode of taper is analyzed.
