【分析】液體內部存在壓強,其特點是:液體對容器底和容器壁都有壓強,液體內部向各個方向都有壓強,液體內部壓強隨深度的增加而增大,在同一深度,液體內部向各個方向的壓強相等,不同液體內部的壓強還與液體的密度有關;故橡皮膜的形狀由玻璃管所受的液體壓強大小決定,故據此分析即可判斷.
【解答】解:A、玻璃管下端更深,所受的液體壓強更大,所以應該是下面橡皮膜向上凹得更厲害些,故A錯誤;
B、玻璃管下端更深,所受的液體壓強更大,且下面橡皮膜向上凹得更厲害些,故B正確;
C、玻璃管水平放置在液體中,液體對兩側橡皮膜有向內的壓強,所以右側橡皮膜應該向左凹,故C錯誤;
D、玻璃管水平放置在液體中,兩側的橡皮膜都應向內凹,故D錯誤;
故選B.
【點評】本題考查了學生對液體壓強公式的掌握和運用,分析時同時考慮影響液體壓強的多個因素(如深度、密度).
