Who can tell me these two conceptions

[Silicon]

What is "the disjoining pressure" and What is "the Hamaker function".

 

[marlon]

Where did you read about these concepts ?
Can you give a reference to a text where they appeared ?

This paper might help to explain the Hamaker function (and Hamaker equation, Hamaker constants).

The process of EPD is described by Hamaker's equation, which relates the instantaneous yield rate with the electric field.

As for disjoining pressure - see "http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JAPIAU000098000012124906000001&idtype=cvips&gifs=yes "

Also see - Lifsh!tz theory (where ! = i, in order to avoid auto-censor )

van der Waals Interaction, Surface Free Energies, and Contact Angles: Dispersive Polymers and Liquids
http://www.ms.unimelb.edu.au/~dyc/pdfs/115.pdf

which mentions Lifsh!tz theory and Hamaker equation and constants.
