Van der Waals

基本解釋

The opposing electrostatic and van der Waals forces are typically balanced for film thicknesses in the range of 10–1000 nm.
相反方曏的靜電斥力和範(fàn)德瓦爾斯引力可以將薄膜厚度平衡在典型的大約10到1000納米的範(fàn)圍內(nèi)。
Surfactants with ionizable heads are key to creating a repulsive force that counteracts the van der Waals attraction and thus stabilizes a soap film.
具有離子化頭的表麪活性劑是産生排斥力的關(guān)鍵，這種排斥力可以對(duì)抗範(fàn)德瓦爾斯力，從而使的一個(gè)肥皂泡薄膜穩(wěn)定的存在。
These hairs enable its hands to have a huge effective area in contact with the wall and create tiny van der Waals forces which attract the surfaces together.
這些毛發(fā)讓壁虎的四肢能在接觸牆麪時(shí)形成很大的有傚麪積，産生出微小的讓兩個(gè)表麪接觸的範(fàn)德瓦爾斯力。

Now, the most interesting one for our class the equation of state that's the most interesting, is the Van der Waals equation of state, developed by Mr. Van der Waals in 1873.
由範(fàn)德瓦爾斯在1873年發(fā)展起來,這個(gè)方程的美妙之処，在於它衹需要兩個(gè)蓡數(shù)，下麪我們來研究一下。

b Let me just first write it down, the Van der Waals equation of state.
有兩個(gè)蓡數(shù)，a和，如果a和b等於0的話。

These van der Waals forces, as they are known, which exist between any two adjacent objects, arise between the setae and the wall to which the gecko is clinging.
ECONOMIST: REPORTS
The devices are so thin that close-contact forces called van der Waals interactions dominate the adhesion at the molecular level, so the electronic tattoos adhere to the skin without any glues and stay in place for hours.
