物理實驗The Dipping Bird翻譯中文
When the bird is manufactured, most of the air is removed from the inside. The gas that remains is largely the vapor from the red liquid, which vaporizes very easily. When the fuzzy coating on the bird's head is wet, water evaporates and cools the vapor inside the bird's head. This condenses the vapor back to red liquid and reduces the pressure in the bird's head. When the fuzzy coating on the bird's head is wet, water evaporates and cools the vapor inside the bird's head. This condenses the vapor back to liquid and reduces the pressure in the bird's head. The bird's head keeps moving.
Since the pressure of the vapor in the bird's body is now higher than the pressure in its head, liquid is forced from the bottom up the tube toward the head. As the liquid moves up the tube, the center of gravity of the bird is raised, and the bird begins to tip around its fulcrum. When the bird finally dips into the water, a clear passage is opened between the head and the body, allowing the pressures to equalize and the liquid to fall back down to the body. The bird returns to the upright position and the whole process repeats.
Each time the bird's beak dips into the water, the fuzzy material absorbs a little water to replace any that has evaporated. This prevents the bird's head from drying out. The bird will continue its cycle until the head dries out, and evaporation can no longer cool it.
In summary, the steps in the cycle are as follows:
* The bird's head dips and gets wet.
* Water evaporates from the fuzzy head.
* The vapor in the bird's head condenses into liquid.
* Pressure in the bird's head is reduced because the liquid takes up less space than the vapor.
* Liquid moves up the tube into the low- pressure area in the head; the cycle repeats.

當鳥是製作的， 大多數空氣從裡面被取消。 依然是的氣體主要是蒸氣從紅色液體， 哪些非常容易地汽化。 當模糊的塗層在鳥的頭是濕的， 澆灌蒸發并且冷卻蒸氣在鳥的頭裡面。 這在鳥的頭凝聚蒸氣回到紅色液體并且減少壓力。 當模糊的塗層在鳥的頭是濕的， 澆灌蒸發并且冷卻蒸氣在鳥的頭裡面。 這在鳥的頭凝聚蒸氣回到液體并且減少壓力。 鳥的頭保留移動。
因為蒸氣的壓力在鳥的身體壓力現在是更加高於在它的頭， 液體從新被強迫管往頭。 液體移動管， 重心鳥的被上升， 并且鳥開始在它的支點附近打翻。 當鳥最後浸洗入水，一個清楚的段落被打開在頭和身體之間， 允許壓力調平和退回的液體下來對身體。 鳥回到垂直位置和整體過程重覆。
每次鳥的額嘴浸洗入水，模糊的材料吸收少許水替換蒸發了的任何。 這防止鳥的頭變乾。 鳥將繼續它的週期，直到頭變乾， 并且蒸發可能不再冷卻它。

examplt: 當鳥剛被做出來時,裡面大部分的空氣就被除去了! 留在裡面的空氣,通常就是非常容易揮發的紅色液體的蒸氣,.....
