【摘要】：蛋殼沒有顯著的接觸變形,水洗干燥之后難以在堅硬光潔的平面上直立;但依賴兩三顆細小鹽粒或者水膜的輔助支承即可實現(xiàn)大端直立.蛋在液體中姿態(tài)與浮力有關(guān),可在水中以小端直立.與剛體、浮體相同,潛體在重力、浮力和支承力作用下處于穩(wěn)定平衡時勢能達到極小值.
[Abstract]:The eggshell has no obvious contact deformation, it is difficult to stand upright on the hard and clean plane after washing and drying, but it can be achieved by two or three small salt particles or the auxiliary support of water film. The attitude of eggs in liquids is related to buoyancy and can be held upright at small ends in water. As with rigid body and floating body, the potential of submersible body in stable equilibrium under the action of gravity, buoyancy and supporting force can reach a minimum.
