潜水艇的沉浮原理

潜水艇的沉浮原理 潜水艇的沉浮演示实验 (演示潜水艇的沉浮原理) 实验仪器:潜水艇由球形气室(顶端有进排气孔，底端有进排水孔和 配重块)、胶管、吸排气筒组成，烧杯和水。 requirements of construction sites, will be shut down. No residue of all closed transport vehicles, shall be seized. Firmly close the cancellation illegal quarry stones within the main road on both sides of the Visual factory, factory will be shut down. Third, prevention and 1( 把潜水艇轻轻放入水中，这时，潜水艇浮在水面上。 2( 将吸排气活塞缓缓向外拉，潜水艇气室排气，水从底部进水孔 内吸进，这时，潜水艇随着重量的增加而缓缓下沉。(物体的重 量大于它排开的液体的重量，即重力大于浮力时，物体下沉)。 3( 再将活塞向里推，气室吸气，排水孔排水，潜水艇重量逐渐减 少而缓缓上浮。(物体的重量小于它排开的液体的重量，即重力requirements of construction sites, will be shut down.
