空气泡 (2).png


空气泡    

        根据波义耳定律,当温度不变时,一定量的气体体积与压强成反比。由于液体具有高密度和高粘滞度,分子间的作用力很大,所以形成的气泡具有足够的体积,气泡上升时所受到的阻力较大,故上升的速度缓慢,随着气泡的上升,气泡所受的液体压强逐渐减小,因而气泡也逐渐增大。


AIR BUBBL     

        According to Boyle’s law, when the temperature is constant, the air volume of a fixed amount is reversely proportional to pressure intensity. Because high density and high viscosity of the liquid, the intermolecular acting force is very big, so the air bubble formed has an adequate volume and the resisting force when the air bubble rises up is relatively, therefore the rising speed is slow, but as the air bubble rises up, its pressure intensity acted by the liquid is gradually reduced, thus it gradually becomes big.
