It is great to talk about phenomenon,but there are two mistakes as below:
1. the hydrogen bond is between hydrogen in one water molecule and oxygen in another water molecule, not within one water molecule,not 两个氢原子与一个氧原子通过氢键结合在一起,而成为一个水分子!!!
2. 虹吸现象 occurs if the attractive force between the pipe wall (such glass) and water is bigger than the force between one water molecule and another water molecule, while the wall diameter is relatively small (less than the diameter due to the contact angle).If this force is weaker,for example water in wax pipe, there are no 虹吸现象.
The chain theory is wrong as:
in water there are many hydrogen bond "chains", but in petrol, foe example, there are no hydrogen bond,ie, there are no chains,but the 虹吸现象still occurs,thus the chain theory is wrong!!!
“在表面张力作用下,液体在毛细管中发生虹吸现象。” – 您究竟在陈述什么?
液体在毛细管中上升是液体对管壁的浸润作用与表面张力交互作用的结果:液体首先浸润管壁,然后表面张力将液体拉上来使液面变平,然后液体再浸润管壁……。这是“毛细现象”,不是“虹吸现象”!
“虹吸现象”(Siphon)是什么? Siphon is:
“A tube or conduit bent into legs of unequal length, for use in drawing a liquid from one container into another on a lower level by placing the shorter leg into the container above and the longer leg into the one below, the liquid being forced up the shorter leg and into the longer one by the pressure of the atmosphere.” (http://dictionary.reference.com/browse/siphon)
不知道这里的“虹吸现象”与您说的“氢键”,“表面张力”,“分子之间的作用及和表面的作用”……之类有何关系?
