style="text-indent:25px">流體是氣體和液體的總稱。大氣和水是常見的兩種流體，大氣包圍著整個(gè)地球，地球表面的70%是水面。大氣運(yùn)動(dòng)、海水運(yùn)動(dòng)(包括波浪、潮汐、中尺度渦旋、環(huán)流等)乃至地球深處熔漿的流動(dòng)都是流體的研究內(nèi)容。當(dāng)作用力停止作用，固體可以恢復(fù)原來的形狀，流體只能夠停止變形，而不能返回原來的位置。固體有一定的形狀，流體由于其變形所需的剪切力非常小，所以很容易使自身的形狀適應(yīng)容器的形狀，在一定的條件下并可以維持下來。具有黏性的流體在發(fā)生變形時(shí)將產(chǎn)生阻力，而沒有黏性的流體則不會(huì)有任何阻力，度量流體黏性的物理量稱為流體的黏度。沒有黏性的流體又稱為超流體。廣東卷管器流體公接頭</p></p><br
