2、曲率、曲率半徑的概念及求法

曲線(xiàn)的曲率（curvature）：就是針對曲線(xiàn)上某個(gè)點(diǎn)的切線(xiàn)方向角對弧長(cháng)的轉動(dòng)率。通過(guò)微分來(lái)定義就是：K=lim|Δα/Δs|，Δs趨向于0的時(shí)候，k值就是曲率。曲率表明曲線(xiàn)偏離直線(xiàn)的程度，或曲線(xiàn)在某一點(diǎn)的彎曲程度的數值。曲率越大，表示曲線(xiàn)的彎曲程度越大。

曲率半徑：曲率的倒數就是曲率半徑。

曲率半徑求法：ρ=|[(1+y'^2)^(3/2)/y'']|，K=1/ρ?；?/p>

擴展資料：

曲線(xiàn)，是微分幾何學(xué)研究的主要對象之一。直觀(guān)上，曲線(xiàn)可看成空間質(zhì)點(diǎn)運動(dòng)的軌跡。微分幾何就是利用微積分來(lái)研究幾何的學(xué)科。為了能夠應用微積分的知識，我們不能考慮一切曲線(xiàn)，甚至不能考慮連續曲線(xiàn)，因為連續不一定可微。這就要我們考慮可微曲線(xiàn)。

曲線(xiàn)不是濾鏡，它是在忠于原圖的基礎上對圖像做一些調整，而不像濾鏡可以創(chuàng )造出無(wú)中生有的效果。曲線(xiàn)不是那么難以捉摸的，只要掌握了一些基本知識，你可以像掌握其他工具那樣很快掌握曲線(xiàn)工具，控制曲線(xiàn)可以給你帶來(lái)更多的戲劇性作品，更多精彩都將來(lái)自你手下。
